Our personal carbon footprint is the amount of carbon dioxide that we put into the air when we use electricity, drive a car, and heat or cool the house. Individual effort is especially significant. We can make simple changes in daily behavior to reduce our own carbon footprint. First, walk or bike instead of driving a car. Emissions from cars and trucks contribute to the greenhouse effect. Second, doing recycle and use recycled paper, glass and plastic everywhere. Because they use less energy to manufacture than products made from completely new materials.Third, turn off the heat, air conditioning and lights when you leave the house or go to bed. Finally, plant the trees. Trees naturally offset the greenhouse gases. They take in carbon dioxide and turn it into oxygen. To sum up, encouraging more people to do likewise, we can reduce carbon emissions impact on our lives, on environment and on future generations.
