National government has been looking for ways to help solve the issue on global warming. Is planting trees one of the best ways to help solve the problem? Why or why not?

• Yes, because trees give us shed and protects us from the heat of the sun.

• No, because trees only contribute to the carbon dioxide level in the atmosphere.

• No, because trees only gives off oxygen as its by products in photosynthesis.

• Yes, because trees help in absorbing the carbon dioxide, one of the gases that traps the heat in the atmosphere.
