Climate change is caused by human activities such as burning fossil fuels, deforestation, and agricultural practices that release greenhouse gases into the atmosphere. These gases trap heat and lead to global warming, causing rising temperatures, sea levels, ocean acidification, and extreme weather events. Effects include loss of biodiversity, food and water shortages, and increased spread of diseases.

To mitigate climate change, we must reduce our carbon emissions by transitioning to renewable energy sources such as solar, wind and hydro power. Additionally, increasing forest cover through reforestation and sustainable forest management can help capture and store carbon dioxide from the atmosphere. Reducing waste, conserving water and using energy-efficient technologies are also important steps individuals can take. Finally, governments must implement policies that support these efforts on a global scale.
