Environmental Concerns in Global Politics:

Throughout the world, cultivable area is barely expanding any more, and a substantial portion of existing agricultural land is losing fertility. Grasslands have been overgrazed and fisheries overharvested. Water bodies have suffered extensive depletion and pollution, severely restricting food production.

According to the Human Development Report 2016 of the United Nations Development Programme, 663 million people in developing countries have no access to safe water and 2.4 billion have no access to sanitation, resulting in the death of more than three million children every year.

Natural forests — which help stabilise the climate, moderate water supplies, and harbour a majority of the planet’s biodiversity on land— are being cut down and people are being displaced. The loss of biodiversity continues due to the destruction of habitat in areas which are rich in species.

A steady decline in the total amount of ozone in the Earth’s stratosphere (commonly referred to as the ozone hole) poses a real danger to ecosystems and human health.

Coastal pollution too is increasing globally. Although the open sea is relatively clean, the coastal waters are becoming increasingly polluted largely due to land-based activities. If unchecked, intensive human settlement of coastal zones across the globe will lead to further deterioration in the quality of marine environment.
