Answer:
The burning of fossil fuels
Step-by-step explanation:
The use of fossil fuels, which intensified during the industrial revolution, is associated with several serious environmental problems, especially climate change and the increase in the greenhouse effect.
Carbon dioxide, the gas that is most released during the burning of fossil fuels (as in car engines and other vehicles),is primarily responsible for global warming.
Gases such as sulfur dioxide, are highly responsible for acid rain. This phenomenon can also lead to the destruction of monuments made of masonry or marble and plants that are essential for biochemical oxygen cycles, such as photosynthesis.
