Dr Rajagopalan Vasudevan proves how even an individual effort can clean the face of our country, as he invents new ways to reuse plastic for roads and buildings.

One day, a professor of Chemistry was watching TV. He saw a doctor blaming plastic for water pollution. This set him wondering—how can plastic cause pollution when it is chemically a hydrocarbon and insoluble in water! The doctor was of course mistaken but his concern was genuine: plastic is an environmental nuisance. Polybags have infested our marketplaces, are swallowed by cattle, clog drains, choke ponds… 

Climate change has made the Indian Ocean more unpredictable than ever. On one hand, there are more cyclones emerging out of this ocean, and on the other hand, they are intensifying very rapidly, gaining more power in a very short time. This is called rapid intensification.

The Cheetah is the fastest terrestrial animal on earth, capable of galloping at speeds of up to 100 km/h. The Cheetah, which was extinct in the 1950s in India, is about to make a comeback later this year. About 10 cheetahs, 5 of them females, will be brought to Madhya Pradesh’s Kuno-Palpur Wildlife Sanctuary in November 2021.

The spread of Multi-system Inflammatory Syndrome in Children (MIS-C) has raised concerns among pediatricians. Children manifest this syndrome which usually involves multiple organs about four to six weeks after a COVID-19 infection.

Health experts say that MIS-C happens due to an antigen produced by the body to fight the COVID-19 infection. The lower number of COVID-19 tests conducted on children is the reason for the late detection of post-Covid complications among them.

What is the truth behind India's honey? How pure is the honey made by your favourite brand? Are you eating nature's wonder food or are the companies selling you cheap and unhealthy sugar? To find these answers let us look at the latest report by the Delhi based Centre for Science and Environment or CSE.

CSE has earlier exposed pesticides in colas and packaged drinking water, antibiotics in honey, GMO's in packaged food, and excess salts and trans fat in junk foods...

Schools can play a key role in meeting India's 2022 renewable energy target. Here are a few learnings from the solar initiative of Centre for Science and Environment.

Once upon a time humans depended on the labour of animals and other humans to meet their daily energy requirements. From transport to agriculture, humans made use of natural resources like wind, water and gravity for their energy needs. 

The cultivation of rice has occupied the pride of place in Kerala’s agriculture. Unending lush green paddy fields are a sight for sore eyes. But Paddy cultivation is declining in Kerala at an alarming rate. In the past 30 years, the state lost more than 70 per cent of its paddy fields. Rice producing districts like Wayanad once had 160 varieties of paddy. 55 of these varieties are now extinct. But there are people in the state who are trying to preserve this paddy biodiversity.  

Carrying water by trains could be an emergency measure. Chennai has a strong tradition of water harvesting. But the problem is that most of these structures are either defunct or poorly maintained. Chennai which had 19 major lakes covering an area of 1130 hectares. But these waterbodies have been heavily encroached upon reducing their spread to just about 645 hectares. Its time that we understand the importance of water harvesting.

Sunlight, readily available for 250 to 300 days in most parts of India, can help schools operate better.

India has set a target of 227 GW of installed capacity from renewable energy by 2022. Of this, nearly 144 GW would be sourced from solar energy, while 67 GW would come from wind energy. Although wind, solar, biogas and water are all renewable energy sources for power, solar energy is considered to be the most affordable alternative to polluting fossil-fuel based power-plants. Easy installation and electricity generation also make solar energy the best bet among renewables...

Just step into your house and look around. All our appliances from our refrigerator to air-conditioner to smartphones, everything would become useless in a world without electricity. This is why electricity is considered one the most valuable commodities in the world.
