Green schools are taking initiatives to clean the polluted air around us
As we gear up for winter, we cannot ignore that this is the time when we experience the worst of air quality across cities and towns. The air we breathe is filled with toxic pollutants like nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO), particulate matter (PM 2.5, PM 10), lead (Pb), ozone (O3), among others, arising from multiple sources such as vehicles, industries and power plants.
Delhi has been infamous for its air pollution, for years, especially after the World Health Organisation reported it to be the most polluted city in the world in 2014.
Moreover, Delhi residents are not alone in grappling with air pollution. Many other cities such as Allahabad, Varanasi, Patna and Kanpur are also equally at risk.
There are some schools that have taken up energysaving initiatives to become energy-efficient.
Electric bulbs, cars, fans, air conditioners, televisions, cooking ovens, chulhas, machines... the word ‘energy’ conjures up images of almost everything that makes up our everyday lives. Some forms of energy are renewable, including energy harnessed from the sun, wind and water. Energy produced from garbage, such as dead trees, branches, leftover crops and gobar, or dung, along with other forms of livestock manure—resources collectively called ‘biomass’—can also be used and then replenished.
There is also a second category, non-renewable energy. All forms of fossil fuel—oil, coal and natural gas—are examples. These fuels were made over 300 million years ago and we are slowly and surely depleting the reserves.
Junk lovers, welcome a new addition to the group—the bees. Pollen is the only natural source of protein for bees, but every day it is becoming starchier—thanks to the increasing carbon dioxide in the atmosphere, which is sapping the nutritional quality of pollen. Bees need adequate proteins to feed their larvae and maintain their immune systems; some bees store pollen to tide through winters.
