What activity contributes to the increase of greenhouse gases in the atmosphere?

Burning fossil fuels significantly contributes to the increase of greenhouse gases in the atmosphere. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release carbon dioxide and other greenhouse gases as byproducts of combustion. These gases accumulate in the atmosphere, enhancing the greenhouse effect, which leads to global warming and climate change. Unlike the other options, which are environmentally beneficial, burning fossil fuels is a major source of emissions that trap heat in the atmosphere. In contrast, activities like planting trees help absorb carbon dioxide, while recycling materials and using solar panels reduce reliance on fossil fuels and promote cleaner energy sources.
