The major cost of the greenhouse effect is the increase in carbon dioxide in the atmosphere. This is primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes. Carbon dioxide traps heat in the Earth's atmosphere, leading to global warming and climate change. This in turn has widespread effects on ecosystems, weather patterns, sea levels, and human health.
