The document discusses the causes and effects of climate change and global warming. The primary causes are the burning of fossil fuels and deforestation, which increase levels of carbon dioxide and other greenhouse gases in the atmosphere. This traps heat and warms the planet, leading to consequences like more extreme weather, rising sea levels, and melting ice caps. While some skeptics do not believe humans are responsible, the document expresses the view that humans contribute somewhat but that climate change is also part of a natural cycle. Fighting global warming involves reducing waste and emissions through actions like using less energy and driving less.
