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, habitat destruction, and climate change. For example, the burning of fossil fuels releases greenhouse gases, contributing to global warming and altering weather patterns. Additionally, environmental effects can impact biodiversity, leading to the extinction of species and loss of ecosystems. Deforestation, often driven by agriculture or urban development, reduces the habitats available for wildlife. Protecting the environment is essential for maintaining the balance of ecosystems and ensuring a sustainable future for all living organisms.
