In a process called photosynthesis, the leaves of trees breathe in or absorb CO2 and break it down into carbon and oxygen. The oxygen is breathed out or expelled. That's why we say that trees help to purify or freshen the air.

What is the purpose of planting?

the main purpose of planting trees is to save the environment..... as we all know the ozone layer is become thinner.....which causes global warming.... one of the main gases are carbon di oxide....which traps the heat of the sun and warms the earth's temperature...... trees need carbon di oxide so they reduce its presence but if there are no trees then the earth's temperature will rise and cause a lot of damage... therefore planting trees is the only option since we humans have caused sooo much damage.....

If a tree releases carbon di oxide in night time then what is the use of Tree?

During the daytime, trees undergo photosynthesis, where they take in carbon dioxide and release oxygen. This process helps to purify the air and provide us with oxygen to breathe. While at night, trees respire like all living organisms, releasing some carbon dioxide. Overall, trees are still beneficial for their oxygen production and role in carbon sequestration.
