What causes global warming and how can I help reduce its effects?
assistant
Global warming is caused by the accumulation of greenhouse gases in the atmosphere, which traps heat and causes temperatures to rise. We can help reduce the effects of global warming by reducing our energy use, such as replacing old appliances with more energy efficient ones, using alternative energy sources, using public transportation more, and reducing our carbon footprints. Reducing deforestation, protecting wetlands and planting more trees can also reduce the effects of global warming.
