factories, vehicles, and agriculture can contaminate natural habitats, harming plants and

animals. Water pollution, for example, can lead to eutrophication, where excess nutrients

cause harmful algal blooms that deplete oxygen in water, leading to fish kills.

Deforestation and Habitat Loss

Cutting down forests for timber, agriculture, or urban development destroys habitats for

countless species. This loss reduces biodiversity and can alter the climate locally and

globally. Forests act as carbon sinks, so deforestation also contributes to increased carbon

dioxide levels, intensifying climate change.

Climate Change

One of the most pressing topics within living environment 2013 topic 7 is climate change.

Human activities release greenhouse gases that trap heat in the atmosphere, causing

global temperatures to rise. This warming disrupts weather patterns, threatens species

survival, and affects ecosystems worldwide.
