Quizplus · Accepted Answer

Photosynthesis removes carbon dioxide from the atmosphere, which can help to reduce the greenhouse effect and therefore help to mitigate global warming. While burning fossil fuels can also remove oxygen from the atmosphere, this is not a viable solution to reducing global warming as it has many negative environmental and health impacts. Additionally, global warming is not part of the normal cycle for the planet and is primarily caused by human activities.
