As our population grows, we use more resources like water, fossil fuels, and land. This leads to deforestation, pollution, and climate change. Climate change, in particular, is caused by an increase in greenhouse gases like carbon dioxide that come from burning fossil fuels and other human activities. This can cause sea levels to rise, extreme weather events, and harm to animals and plants. We can lessen our impact by using renewable energy sources like solar and wind power, reducing waste, and conserving resources.
