Work in groups. Carry out a survey to find out how people in your area are reducing the negative impact of their daily activities on the environment and trying to limit global warming.
Report your survey results to the class.
The report should include the following points:
• what their daily activities used to involve, e.g. driving to work
• how these activities affect global warming, e.g. releasing carbon dioxide emissions
• what people do to reduce their environmental impact, e.g. cycling to work
• what results people get, e.g. reducing carbon footprint
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.
