World leaders keep meeting on climate change issue but there is no genuine commitment to the cause
The Covid-19 lockdown last year had one positive fallout - the sky regained its brilliant blue as the perennial haze of pollution lifted and one could see the Himalayan range from far-off places like Delhi and Chandigarh. Metros like Delhi and Mumbai became pollution-free, wild animals started foraging for food in cities and towns, and rivers became cleaner. This is, however, a grim reminder that humanity must change its materialist, extravagant lifestyle and establish equilibrium with nature. That is the special message of the pandemic.
When the air pollution levels came down, there was a perceptible decline in respiratory diseases.One study said the improved air quality index on account of reduced human activities in Chennai was similar to that of European countries. The forests got a reprieve with reduced instances of forest fires, illegal felling of trees, and poaching. This writer noticed how migratory birds which normally returned home during February-March stayed back till May end. In zoos sans tourists the animals regained their natural composures and behaviours. In the Satpura Tiger Reserve of Madhya Pradesh, tigers,which had got used to regular movement of tourists,started liking their isolation and fretted upon seeing forest guards on patrols. According to Central Pollution Control Board, the Ganga, Yamuna, and Gomati rivers' water became cleaner. Dolphins were sighted in the Ganga near Meerut.
These examples tell people to adopt climate-friendly behaviours in their day-to-day lives. Look at Jadhav Payeng from Jorhat, Assam who got the 'Forest Man of India Award' in 2010 for turning 550 hectares of barren land into a lush green forest.
National Governments the world over started climate change negotiations after the Kyoto Protocol came into being in 2005. However, there is no genuine commitment to climate change even though world leaders meet every now and then because of never-ending politics. In India too, despite good initiatives like the solar alliance, the bureaucracy is unable to stem the rot in the field of environmental conservation.
Let us consider some citizen's initiatives which can make a big difference to the environment. Let us go for water harvesting and recharging in every home. Climate change was responsible for about 74 per cent of flash floods and droughts in the last 20 years. In cities 90 per cent of rainwater goes waste because of excessive construction activities. In contrast, 90 per cent of the rainwater gets absorbed in forests, recharging the aquifers, streams, and rivers. Every household having a 200 sq. mt. area can recharge around two lakh litresof rainwater every year.
Second, each tree gives oxygen for 10 people to survive. Everybody should plant a tree every year. A big tree absorbs 21 kg of carbon dioxide (CO2) and in 100 years reduces one tonne of CO2.
Third, food wastage is the biggest environmental problem as it wastes water and food grains. In 2019, nine billion tonnes of food was wasted in the world, releasing 70.41 lakh tonne methane gas. If we stop this wastage, eight percent reduction in greenhouse emissions can be ensured. Four, we must stop the use of paper cups to save at least 65 lakh trees and billions of gallons of water. Five, we need to use electricity carefully because 40 percent of carbon emissions are due to electricity production. If we can switch off the wi-fi and laptops we can reduce the emissions by 16 percent. Six, cars contribute to huge carbon emissions and if we limit the car speed to 70 kmph, it will reduce emission by 8 percent. The principle is at the speed 100 kmph the emissions increase by 28 percent.
