The biggest issue facing the world today is climate change. Climate change is caused by human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. These gases trap heat and cause temperatures to rise, leading to extreme weather events, rising sea levels, and melting of polar ice caps. This will have serious consequences for the environment, economies, and societies around the world.
