Last 10 Days Environment Revision Strategy for Prelims 2020

Life is always inspired by Nature no matter what form it takes. The food we intake, the air we breathe, the land where we live are the gifts of nature to mankind.

Co-existence is the only principle of nature being taught to everyone. Plants, Animals, Humans everyone has to coexist and live in harmony with each other.

Extinction of anyone leads to threats for others. Today, Coronavirus has shown the world ‘Why co-existence with nature is a must’

When we all were at home, Nature was enjoying. We have seen Mass nesting of Olive Ridley Turtles at Rushikulya rookery in the ganjam district of Odisha, Gangetic Dolphins in Vikramshila Gangetic Dolphin Sanctuary in Bihar, Nilgai in Sector 18 of Noida, and many more beautiful events.

If we are determined to co-exist happily with nature, nothing is impossible. As we have achieved our target to doubling the numbers of Tigers in India four years before the target year of 2022.

Now coming to topics, let me tell with assurance that this year biodiversity and threat to wild life will be asked in Prelims. The questions can be framed in many ways like what can be possible reasons for increase of Zoonoses. WWF has come out with a report on this issue which was widely reported. So prepare biodiversity in depth. You can refer NCERT BIO book. Concept of one health can be asked.

Climate change is another big threat facing humanity. Food shortage, Extreme weather conditions, melting glaciers, warmer temperatures are all consequences of climate change.

We have also seen How the Great Barrier Reef has suffered mass coral bleaching due to warmer temperatures. A pacific nation becomes first in the world to ban chemical sunscreen to protect its coral reefs.

The (IPCC) Intergovernmental Panel on Climate Change made public ‘Special Report on the Ocean and Cryosphere in a Changing Climate’ which stated the changes occurring in glaciers, oceans, and ice-deposits on land and sea.

This report focussed on Oceans by stating their unprecedented situations due to Ocean Acidification, Increased Temperatures, Marine heatwaves, and extreme El Nino and La Nino events.

Carbon Capture is being discussed by several scientists to mitigate global warming and to avoid the harmful effects of climate change.

Amidst COVID 19 pandemic, Vizag styrene gas leak, Cyclone Amphan, We have seen another disaster in form of a Locust attack. Swarms of Desert locusts have entered from

Pakistan to western India & impacted several states. One of the main reasons for this locust attack is decreasing birds’ population and climate change.

Among international bodies, GEF has been in news. Prepare it properly.

  1. IPCC

Before Coronavirus India was producing 600 tonnes of Biomedical waste per year but After Corona, We have seen a tremendous hike in the generation of Biomedical waste. It is creating newer threats for the environment too. Therefore, It becomes the most important topic to find a place in UPSC prelims 2020.

India also faces a severe threat of Land desertification. 30% of its land area has been degraded through soil erosion, deforestation, extreme weather conditions, or over-cultivation that can impact India’s GDP by 2.5%. UNCCD can be a asked.
