Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil

Green House gases

• absorb the sun's radiation and trap heat

• are good for our health

• absorb gravity and keep us attached to Earth

• expulse radiation to the sun and prevent us from getting to warm

What would be Earth's temperature without green house gases?

• Earth's temperatures would be cold, oceans would freeze

• The same, green house gases do not affect Earth's temperature

• Earth's temperature would be 90 Fahrenheit
