A country's 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 the

  photosynthesis.

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

What are the important roles of the greenhouse gases?

I. It is necessary for communication.

II. It reflects back the sun’s rays to Earth to keep it cold.

III. It helps the Sun in providing the energy needed by Earth.

IV. It absorbs infrared radiation from the earth and re-radiate it back to the Earth.

What do greenhouse gases do?

• Reflect the sun's energy
