Which of the following activities is a significant contributor to the increase in carbon dioxide levels in the atmosphere?*1 pointa) Planting treesb) Driving electric carsc) Burning fossil fuelsd) Using solar energy

The activity that significantly contributes to the increase in carbon dioxide levels in the atmosphere is c) Burning fossil fuels.

Here's why:

1. Burning fossil fuels: When we burn fossil fuels like coal, oil, and gas, they release carbon dioxide into the atmosphere. This is a major source of greenhouse gases and contributes significantly to global warming.

2. Planting trees: This activity actually helps to reduce carbon dioxide levels. Trees absorb carbon dioxide from the atmosphere during photosynthesis, a process that converts carbon dioxide and sunlight into oxygen and glucose.

3. Driving electric cars: Electric cars produce less carbon dioxide emissions compared to conventional cars. However, the production of electricity used to charge these cars can still contribute to carbon dioxide emissions, depending on the source of the electricity.

4. Using solar energy: Solar energy is a renewable source of energy that does not produce carbon dioxide emissions. Therefore, it does not contribute to the increase in carbon dioxide levels in the atmosphere.
