Lakshmi Menon, an Ernakulam-based social entrepreneur and designer, has fashioned eco-friendly mattresses for COVID-19 patients from PPE scrap material.

When Lakshmi Menon saw a poor family sleeping on the bare ground, she decided to do something to help the needy. In March 2020, she conceived the idea of shayya mattresses made out of tailoring scrap.

PPE to the rescue

As the COVID-19 pandemic hit the country, hospitals and First-Line Treatment Centres (FLTCS) in Kerala struggled to provide enough beds for patients. Mattresses became the need of the hour, each one costing between 500-700. When Lakshmi called up tailoring units for scrap to make shayyas, she discovered that they had switched to making personal protective equipment (PPE) suits for healthcare workers. A lot of scrap material is generated while making these suits. As it contains small amounts of plastic, it can be disposed of or recycled by a professional agency only something that many tailors cannot afford. So, they would get rid of the scrap by burning it, causing air pollution. Lakshmi then decided to create shayyas from PPE scrap.

These mattresses are easy to make, requiring no stitching. The scraps are braided together and arranged in a zigzag manner before their ends are tied together with scrap cloth. The resulting shayya is 1.8 m (6 ft) long and 0.7 m (2.5 ft) wide. Unlike a regular mattress, which is difficult to disinfect, it can be washed with soap and reused.

Jobs for local women

 Lakshmi employs around 20 local women who had become jobless during the lockdown. Each woman makes one shayya a day, for which she is paid 300. A shayya is sold at the same price to cover the labour charge. Around 700 shayyas have been donated so far.

Lakshmi's innovative project addressed three major issues - waste management, job creation and the lack of bedding for patients. It has t been recognised by the United Nations in their list of best practices. To enable NGOs, students, etc. to replicate her model, Lakshmi provides them with online training.

Julia Lorraine Hill (known as Julia Butterfly Hill, born February 18, 1974) is an American environmental activist and tax redirection advocate. She is best known for having lived in a 180-foot (55 m)-tall, roughly 1500-year-old California redwood tree for 738 days between December 10, 1997 and December 18, 1999.

When Julia Lorraine Hill was seven years old, a butterfly landed on her finger during a hike with her family in Arkansas, USA. Amazingly, it stayed there for the rest of the hike, earning her the nickname 'Butterfly'.

At age 22, Julia was in a near-fatal car accident. The crash changed her life. She decided to become an eco-warrior.

Hill climbs Luna

Julia joined the movement to preserve the redwood forest in Humboldt County, California. Hundreds of the massive, ancient redwood trees were marked for cutting down by the Pacific Lumber Company. Several activists prevented the loggers from chopping the trees by climbing them and staying put for a few hours, sometimes a few days. Julia chose a 55-m-tall redwood that was almost 1500 years old and climbed it on December 10, 1997. She called it Luna because she had ascended it on a moonlit night.

Though she hadn't planned on it, the days turned into weeks. Soon, the 24-year-old had spent 42 days atop Luna, longer than anyone else! Volunteers from Earth First! and other organisations helped her build a covered shelter on top of the tree.

Succeeds finally

During her 738-day vigil, the logging company subjected Julia to loud horns and blinding lights. They flew helicopters so close that she was buffeted by strong winds from the rotors. She also lived through one of the worst winters in California history. However, Julia stuck firm. She only came down on December 18, 1999, when the company agreed to preserve Luna and create a three-acre buffer zone around itJulia wrote a memoir called The Legacy of Luna and continued to work actively against deforestation. She set up Circle of Life, a foundation that offers tools for sustainable living.

It's unnecessary light which creates health hazards for humans and animals, and affects the ecosystem. Ms. Sumaira Abdulali, an activist who has been fighting against noise pollution, is now urging the government to regard light pollution as a serious environmental hazard and frame a regulatory policy to make night-time lighting safer. Learn more about light pollution and what we can do about it here.

What is unnecessary light?

 Flashing lights and additional colours in hoardings, halogen lights, car headlights, street lights using blue LED lights of high intensity are a few examples (the International Dark Sky Association recommends using LEDS of 3000 Kelvin or below).

Wrong lighting is also hazardous. For example, street lamps that don't light up an area uniformly create patches of brightness followed by darkness. If they are not shielded and set on high masts. the light gets projected onto the eyes of residents or they get directed into the sky, causing a sky glow and blotting out the moon and the stars.

Light is necessary, so how can we prevent it from becoming a hazard?

 Use light only when needed and in the required amount. Use better lights, not brighter lights. Instead of using very bright lights that light up only particular areas, have lights that light up the room evenly. Switch over from blue light to yellow light. Blue light creates glare impairs vision and brightens the sky more than any other colour. Have shades for lights. Deploy motion sensors instead of leaving lights on all night. Also avoid watching TV or working at the computer at night without lights.

What should the government do?

 The government should plan a proper lighting policy with rules regarding what is the right amount of light, what is appropriate light and state the limit for light pollution. It should see that car headlights are checked for colour. intensity and beam angles so that they don't create temporary blindness in drivers of oncoming cars. pedestrians and people living close to the streets.

It should hold advertisers responsible for light clutter (grouping of lights that cause confusion and distract from obstacles, potentially causing accidents). It should also ensure that street lights are shielded, placed at the right distance from each other and at the right height and angle, so that they project light down onto the street..

What can children do to reduce light pollution?

Children should be taught about light pollution. They could use a single yellow light. that would brighten up the entire room when they want to study or read but at other times, they could make use of low voltage lights. They should also turn off lights when not in use.

Pollution is considered to be one of the world's biggest environmental threats. Here are ten shocking facts about pollution.

1. Plastic pollution adversely affects marine life. Over 1 million seabirds and 1,00,000 sea mammals are killed by plastic litter in the oceans every year.
2. In January 2019, the Ministry of Environment. Forest and Climate Change (MOEFCC) launched the National Clean Air Programme (NCAP) to monitor and curb air pollution around the country. It aims to reduce air pollution in 122 cities by 20-30 per cent by 2024.
3. According to the World Air Quality Report, 2020' released by the Swiss organisation, IQAir, New Delhi is the most polluted capital city in the world. Altogether 35 Indian cities are among the world's top 50 most polluted cities.
4. River Ganga flows through many urban centres such as Kanpur, Patna and Kolkata, which dump their industrial effluents and wastewater in the river. The entire length of the river is polluted by the presence of faecal coliform bacteria (germs found in the faeces of warm-blooded animals and humans), making its waters unfit for bathing and drinking.
5. About 70% of water sources in India are severely contaminated. Every year about 37.7 million Indians are affected by waterborne diseases.
6. Noise pollution is one of the most under-rated forms of pollution. According to the World Health Organization (WHO), noise above 65 decibels (dB) is termed as noise pollution. Sounds becomes harmful when its exceeds 75 decibels (dB) and painful when it is above 120 dB.
7. Only 20% of about 3.5 million tonnes of solid waste that our world generates every day is recycled, thus overwhleming the landfills with unmangable quantities. Waste is often disposed of at hazardous open dump sites in developing nations including India causing land pollution. Indiscriminate use of chemical fertilizers and pesticides has led to degradation of soil. making it infertile.
8. According to the WHO, air pollution kills about seven million people worldwide every year. Almost all of the global population (99%) breathe air that contains high levels of pollutants.
9. 80% of the world's wastewater is released back into the environment-most of it untreated, in the developing countries. Farm runoffs containing minerals such as nitrogen and phosphurus causes nutrient pollution leading to algae bloom. This destroys marine life and even results in permanent 'dead zones.
10. The Asian Brown Cloud (ABC) is a dense fog of pollutants that blankets South Asia from November to April. It hovers over western China, northwest Pakistan, Afghanistan and the Indo-Gangetic plain in northern India. The cloud is almost three kilometres thick. It contains a deadly cocktail of aerosols, ash, soot and other particles, 80 per cent of which is caused by human activity.

Your carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by your actions. This includes everything from production, use and end-of-life of a product or service that you consume.

While the global average carbon footprint is close to 4 tons, it is as high as 16 tons per person in a country like the U.S. In order to achieve the net-zero targets that we have set ourselves for 2050, this average figure has to be brought down to under 2 tons per person by then.

This daunting task can be made achievable by breaking it down suitably. By understanding your carbon footprint and reducing it with changes in your lifestyle, it is possible to make a big difference.

HOW CAN YOU CALCULATE YOUR CARBON FOOTPRINT?

There are many online calculators that help you find out your carbon footprint. Most of our daily activities like using electricity, driving a vehicle, or disposing waste. Cause greenhouse emissions. All these emissions together make up our household's carbon footprint. Transportation, housing and food are the three broad categories that form the bulk of an individual's carbon footprint. You will need to know the following details to key into a calculator and find out your carbon footprint:

1) Energy usage in your house.

2) Fuel consumption for cooking.

3) Average distances travelled by flights, car, two-wheelers, bus and train.

4) Composition of diet and average money spent on shopping and various other consumables on a weekly/monthly/yearly basis. Once you have a ballpark estimate of these values, you can then enter them into a calculator like this one: v.gd/cfcalc

Your carbon footprint across categories and the total will then be displayed, comparing it with India's average (if you had used our link) and that of the world's.

Knowing your carbon footprint is the first step towards reducing it. And when you reduce your carbon footprint, you will not only save the planet, but also increase your own savings.

HOW CAN YOU REDUCE YOUR CARBON FOOTPRINT?

Knowing your carbon footprint is the first step towards taking action. Once you are more aware of the effects of your actions, then it is possible to start with small changes in your lifestyle that might eventually make a big difference.

Here are some pointers that you and your family can act upon

1) Think about how much and how often you travel. Cut down where you can, especially air travel, and try to make the unavoidable trips more climate-friendly.

2) Be conscious of what you are eating. By eating low down the food chain as frequently as you can, you will not only be able to reduce your carbon footprint, but also stay healthier in the process. Eating everything on the plate is also very important as wasting less food helps you cut down on your carbon footprint while also saving you some money.

3) Make small changes in your home. Be it turning off lights and appliances when not in use, choosing renewables, recycling products, or making your home more energy efficient, there are plenty of things that you can do to save energy and money.

4) By buying less, shopping sustainably and adding your voice to the climate change discussion, you will be able to achieve more towards saving our planet.

A person of exemplary calibre and fierce patriotism, former President Dr. A. P. J. Abdul Kalam embodied the best of what an Indian can aspire to be. Let us look at one of his most memorable addresses titled, 'My vision for India'.

On May 25, 2011, Dr APJ Abdul Kalam gave one of his greatest speeches at the IIT Hyderabad campus, titled 'My vision for India.’ His simple and self-explanatory inaugural address for the IIT TechFest outlined his aspirations for his motherland and highlighted the need to increase meaningful public participation in nation-building activities.

A man of action

One of India's most celebrated scientists Dr. Kalam was an aeronautical engineer by training. His 1998 project The Technology Vision 2020' was an action plan that sought to achieve economic growth through technological development, with special emphasis on facilitating agriculture and increasing the accessibility and quality of healthcare and education. During his tenure as the 11th President of the country(from 2002 to 2007), India's 'missile man, as he was popularly called in the media, promoted the advancement of the national nuclear weapons program, and under his leadership. India developed strategic missiles like 'Agni and Prithvi' and tactical missiles like 'Aakash' and Thrissur’.

Even after the end of his official term Dr Kalam's passion for education and societal transformation came to the forefront in his addresses across various cross-sections of society from school children to policymakers.

His visions for India

"In 3,000 years of our history, people from all over the world have come and invaded us, captured our lands and conquered our minds... Yet, we have not conquered anyone. Because, we respect the freedom of others, and this is why my first vision is that of freedom. I believe that India got its first vision of this in 1857, when we started the war of Independence. It is this freedom that we must protect and nurture and build on." (an excerpt from My vision for India)

Dr Kalam sought the freedom that nurtured creativity and independent thinking. Freedom that instilled the courage to stand one's ground against all odds. He wanted India to be confident in its identity, and progress towards becoming a developed nation, self-reliant and self-assured.

"We have been a developing nation for fifty years... my second vision for India is development. (an excerpt from My vision for India) In his public addresses, he often asked his audiences to repeat the dictum "Dreams transform into thoughts and thoughts result into action". He really believed that the day we as citizens recognised our duties towards the development of our nation (dismissing all the personal biases) and joined forces to work towards identifying and meeting the needs of 'all' India will truly become developed.

"I have a third vision. India must stand up to the world. Because I believe... Only strength respects strength. We must be strong not only as a military power but also as an economic power. Both must go hand-in-hand." (an excerpt from My vision for India) He ends his speech by echoing J.F.Kennedy's words to his fellow Americans to relate to Indians... Ask what we can do for India and do what has to be done to make India what America and other western countries are today." (an excerpt from My vision for India)

QUICK FACTS ON KALAM

• Born in a humble household of Rameswaram, Tamil Nadu, Dr. Kalam distributed newspapers as a 10-year-old to supplement his family's income.
• Dr. Kalam was the project director of the SLVIII, the first satellite launch vehicle that was both designed and produced in India.
• Dr. Kalam was fondly called People's President because of his simplicity and love for his countrymen.
• Dr. Kalam was the first Asian to be honoured with Hoover Medal. America's top engineering prize for outstanding contribution to public service on April 29, 2009
• In 2012, Dr Kalam launched a campaign called What Can I Give Movement, to develop a "giving" attitude among the youth and to encourage them to contribute towards nation building by taking small but positive steps.

From boosting creativity to instilling mindfulness, boredom can do much for your brains, studies suggest.

When was the last time you felt bored? Truly bored-where you had nothing to do, or didn't feel like doing anything? When you had to watch lonely clouds in an empty sky through your window or just wander aimlessly around the garden at home, picking at leaves or observing ants walking in a line up a wall?

Chances are that such instances of abject boredom would be few and far between. People today have fewer reasons to feel boredom as the avenues for entertainment and mental Occupation are plenty. While children of the eighties and nineties often spent some or the whole of their summer vacations dealing with various forms of boredom, children today often do not have time to get bored. They have activities packed through their vacations, they have the internet, OTT and video games to keep their brains constantly stimulated and entertained.

But do you want to eliminate boredom completely? Ask researchers.

How boredom can be good for you

Turns out that an idle mind is not the devil's workshop, after all. According to studies conducted by neuroscientists, boredom can be good for you.

Psychologists James Danckert and John D Eastwood in their 2020 book Out of my Skull: The Psychology of Boredom, say that boredom can push us to realize our potential and lead full meaningful lives.

 Without boredom there would be no daydreaming or no room for reflection, both essential for a healthy mind. Daydreaming is where creativity stems from Feeling bored is unavoidable, but it is not a judgment on one's character or ability, say researchers.

On the contrary, the very feeling could steer the mind towards ideas and creativity. Unstructured time (with no specific events on the schedule) can help children and adults come up with creative solutions to problems, improve social interactions and learn to develop a sense of self-contentment.

In one of his early writings, British philosopher Bertrand Russel advises parents to allow children the freedom to experience "fruitful monotony. This "doing nothing" would make them more inventive and imaginative, he says.

So, what exactly is boredom?

Boredom is defined as an emotional and psychological state when the individual has nothing particular to do and he or she feels that the period is dull or tedious. It is often described as an unpleasant experience. Imagine standing in a long queue at a supermarket or waiting for a bus or at an airport. Essentially, these periods of nothingness are usually described as boring.

In a classroom, for instance. Haven't you felt bored in certain classes? Well, you are not alone. Studies say it is perfectly normal to feel boredom in a learning environment when the subject being taught is too difficult or too easy.

Technology to the rescue

As soon as electronic devices took over, we have learnt to avoid boredom. We swipe away at our smartphones, going through our social media feeds, playing a game or just listening to music

Technology has had a huge impact on our capacity to feel boredom. It fills up empty time pockets of our lives so well that boredom sometimes has even come to mean the absence of technology. That said, overuse of gadgets has led to a sense of fatigue. How much can you play the same game? How much of other people's lives do you look at?

How to deal with boredom

Do not try to fight it. Accept it and let your mind wander aimlessly. Create a new routine. Each time you get bored, find a new activity to do.

Avoid quick fixes. Try not to reach out for your games or the TV when you are bored. Passive engagement will do great things for you.

Rest, refresh

Consider boredom as a period of rest for the brain. Leave a little time in a day to get bored. You might discover new hobbies and interests, leam to be mindful, or even leam something new about yourself. Maintain a book of boredom and note down the thoughts that come to mind. At the end of a week or month, if you flip through the pages, you would get fresh insight into your own mind.

Boredom is not unique to humans. Animals get bored too. If you look at pets, even if they are healthy and cared for, they could still feel bored if left alone. Being confined in the same space can lead to a lack of stimulation and boredom. Pet owners can help their pets by giving them extra time, attention, more inventive toys or food puzzles.

One reason determining if animals get bored or not is difficult is the tendency of human observers to assign human emotions and expressions to their non-human test subjects. Some animals may display a glassy-eyed stare or apparent disinterest in their outside environment, but this does not necessarily translate to the human concept of boredom. Some animals spend hours at a time simply waiting for a promising food source to arrive. While these animals may appear to be listless or disinterested, it might be more accurate to describe their state of mind as dormant or semi-conscious.

Other animals, especially those with higher functioning brains, can indeed become bored following an extended lack of mental stimulation. When higher functioning animals get bored, they may invent stimulating games or visit unexplored sections of their habitats. This behavior is remarkably similar to the pointless but mind-stimulating projects humans often engage in when faced with hours of inactivity.

Some may argue that an animal's attention span can be extremely short in general, which means what humans might consider signs of boredom may simply be a temporary lack of mental stimulation. While some animals may display signs of boredom, they may not actually have the capacity to form such a complex emotion. It is possible that many animals live more in a more delineated "excited/not excited" state of mind, which would still allow for a sense of boredom, but not the same sense of frustration humans associated with true boredom. When many animals get bored, they simply live in a disconnected emotional state until something new arrives to break the monotony. Animals living in zoos, for example, may sit quietly for hours until visitors arrive.

Pollination is an essential part of plant reproduction. Pollen from a flower's anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.Flowering plants have a number of tricks in their armoury to attract pollinators, whether they are birds, insects, reptiles or mammals. Let’s look at some of the pollinators.

Hummingbirds and Sunbirds

Flowers that hummingbirds and sunbirds favour are day-blooming, tube-shaped. bright orange or red in colour and have little fragrance. Their nectar is 26 per cent sugar, double the amount in a soft drink. The shape forces the bird to delve deep, brushing its head against the stamens which drop their load of pollen.

Sunbirds like to perch while feeding so their favourite plants provide them a stalk to sit on. The rats tail plant of South Africa has a vertical one that provides a convenient foothold for the malachite sunbird while it samples the nectar. Scientists have found that plants with perches have double the number of sunbirds visiting them.

Lizards

On tiny oceanic islands, lizards pollinate the flowers! The blue-tailed gecko is partial to the nectar of the Trochetia flower on the island of Mauritius. It prefers the flowers that grow underneath the pandanus shrub since it shields the lizard from birds of prey. Trochetia plants have over time, evolved to grow in the shelter of the pandanus!

Moths and Butterflies

Hawk moths visit flowers that bloom at night or at dawn or dusk, times at which they are active. The flowers are generally large, showy, and sweetly fragrant. are white in colour and have lots of nectar.

Flowers visited by day-flying moths are smaller, have less nectar and grow in heads rather than individually.

Butterfly-pollinated flowers are similar to the hawk moth-pollinated ones and have petals that provide a landing area. Their nectar is hidden inside narrow tubes which are a perfect fit for a butterfly's proboscis.

Bees and Wasps

Beers are of course, the supreme pollinators, but wasps are not far behind. Some fussy plants demand special attention. Tomato flowers have anthers that will only release pollen if they are vibrated briskly by the whirring wings of the bumblebee! This is called buzz pollination Honeybees are not so good at buzzing!

Fig trees display the ultimate in finicky behaviour. Each species of fig depenits on its own kind of wasp for pollination. A figs flower grow inside the fruit. The female wasp makes a small hole and squeezes inside. Once in, she feeds on the nectar and lays her eggs. When the eggs hatch the new generation of wasps fly to another fig tree. pollinating it in the process.

Bats

Flowers pollinated by bats are flamboyant and white or light-coloured since their visitors are nocturnal like the moths. They are generally bell-shaped and strong smelling. Their pollen grains are bigger and they produce nectar throughout the night Bats pollinate more than 300 species of fruit bearing plants including mangoes, bananas and guavas. Some species of bats sport proboscis-like tongues and have the ability to hover. They also use echolocation to find certain types of flowers.

Lemurs

The world's largest known pollinator is the ruffed lemur of Madagascar. It has dexterous fingers that can peel open the hard coating on the flower of the travellers palm. Once open. the lemur pushes its long snout into it to lap up the nectar. The lemurs depend on these flowers when fruit is scarce. Scientists think the palm's flowers evolved to be pllinatd only by this species of lemur.

Flies

The smelliest flowers around have a corpse-like smell of decay that is immensely attractive to flies. Two of the largest flowers in the world, the rafflesia and the titan arum are pollinated by flies. The paw-paw, a fruit native to the US... depends on flies for pollination Farmers hang rotten meat from the tree to draw in even more of them.

A U.S. start up is behind Terran 1, and could be a pioneering effort in the still-nascent commercial space industry.

Relativity Space is a Los Angeles aerospace start-up that builds rockets using advanced 3D printing technology.

Its debut rocket, the Terran 1, has completed pre-launch testing, ahead of a planned launch window beginning June 30. Originally intended to be ready by 2020, the project is running about 18 months behind schedule. The first rocket launch will carry no cargo and is purely a test flight. If successful, a second flight will carry a NASA payload-it is capable of lifting up to one tonne into low Earth orbit.

The Terran 1 is an intended stepping stone on the way to realising the Terran R, a reusable rocket currently under development, capable of carrying 20 times the cargo of the Terran 1, when it launches in 2024. In order to 3D-print large components, Relativity Space has created "Stargate" a system that it claims is the world's largest 3D printer of metals. It uses existing welding technology to melt metal wire, layer by layer, into precise and complex structures that have minimal joints and parts. The company says it will eventually be able to build an entire rocket (95% of which is 3D-printed) in two months. Traditional methods of construction take 24 months and use 100 times as many parts.
