Hướng dẫn giải

Human is the direct factor that causes global warming and makes this phenomenon more and more serious. The reason is because the increase in CO2 content is mainly due to human activities, such as fuel burning, the reduction in agricultural land use, especially after the industrial revolution.

Helping limited global warming, we should:

1. Drive less

Walk, bike, carpool or take mass transit more often. You'll save one pound of carbon dioxide for every mile you don't drive!

2. Avoid products with a lot of packaging

You can save 1,200 pounds of carbon dioxide if you reduce your garbage by 10 percent.

3. Plant more trees

A single tree will absorb one ton of carbon dioxide over its lifetime.

4. Turn off electronic devices

Simply turning off your television, DVD player, stereo, and computer, when you're not using them, will save you thousands of pounds of carbon dioxide a year.
