Environmental issues refer to problems that harm our planet and affect the health of living things. These issues include pollution, which contaminates air, water, and soil, and climate change, caused by the buildup of greenhouse gases like carbon dioxide. Deforestation, or the cutting down of trees, also contributes to these problems by reducing the number of plants that can absorb carbon dioxide. Another significant environmental issue is the loss of biodiversity, which occurs when species become extinct or their habitats are destroyed. This loss can disrupt ecosystems and lead to imbalances that affect food chains. Addressing these issues requires collective efforts from individuals, communities, and governments to create a sustainable future.
