Question

Examine any four environmental concerns that have influenced the global politics.

Hint:

To score well, link the environmental concern to a specific political treaty or summit (e.g., Ozone layer→ Montreal Protocol; Biodiversity → 1992 Earth Summit).

Answer 1

Step 1: Understanding the Question:
The question asks to identify major global environmental issues that transcend national borders and require international political cooperation and treaties to resolve.
Step 3: Detailed Explanation:
1. Global Warming and Climate Change: The continuous rise in global temperatures due to greenhouse gas emissions has become a central issue in international diplomacy.
It leads to extreme weather events and sea-level rise, threatening the very existence of low-lying island nations, which has spurred global agreements like the Kyoto Protocol and the Paris Agreement.
2. Depletion of the Ozone Layer: The thinning of the ozone layer in the Earth's stratosphere due to CFCs (chlorofluorocarbons) posed a massive threat to global health.
This concern successfully influenced global politics, resulting in the Montreal Protocol, a landmark international treaty to phase out ozone-depleting substances.
3. Loss of Biodiversity: Rapid deforestation and habitat destruction are leading to a massive decline in plant and animal species.
Since biodiversity is considered the 'common heritage of mankind,' its loss affects global food security and medicine, prompting political action like the Convention on Biological Diversity (CBD) signed at the 1992 Earth Summit.
4. Global Water Scarcity: The depletion of freshwater resources and disputes over shared international river basins are growing concerns.
Access to clean water is increasingly viewed as a geopolitical security issue, as scarcity can lead to 'water wars' and mass migrations, forcing nations to negotiate water-sharing treaties.
Step 4: Final Answer:
The four key environmental concerns shaping global politics are climate change/global warming, the depletion of the ozone layer, the rapid loss of biodiversity, and international water scarcity.
