In the process of photosynthesis, trees tend to take up carbon dioxide and water and convert it into oxygen and glucose. In this way, trees help in reducing the amount of carbon dioxide from the air which is otherwise a source of global warming. The process of photosynthesis also yields oxygen which is beneficial for life on earth.
The trees also store carbon inside them hence, reducing global warming. The more the trees, the more will be the chances of carbon being reduced from the atmosphere and being stored in the trees.
Plant processes like transpiration help to lower the temperature around them. Hence, more the trees, lesser will be the rise in temperature.
