Global warming is caused by greenhouse gases such as carbon dioxide, CFCs, water vapor, and methane released from activities like deforestation, agriculture, and fossil fuel use. This leads to extreme weather, rising sea levels as ice caps melt, and effects on ecosystems like coral bleaching, extinction, and algal blooms that destroy fisheries. Individual actions like using less energy, traveling efficiently, afforestation volunteering, and conserving resources can help address the problem.
