Environmental effects refer to the changes in the natural world caused by human activities or natural events. These effects can include air and water pollution, deforestation, and climate change. For example, the burning of fossil fuels releases greenhouse gases, which contribute to global warming and alter weather patterns. Additionally, environmental effects can impact biodiversity and ecosystems. Habitat destruction, often due to urban development or agriculture, threatens various species, leading to extinction. Conservation efforts aim to mitigate these effects by protecting natural habitats and promoting sustainable practices, ensuring a healthier planet for future generations.
