Before we find ways to circumvent the threats of Global warming to human health, we need to understand that Carbon Dioxide is the major contributor to green house effect and Global Warming. And this Carbon Dioxide is the gas that human beings give out when we breathe. Carbon Dioxide when associated with power plants and fossil fuels will be considered harmful. What causes the increase in level of Carbon Dioxide on the atmosphere is when people burn fuels such as when they drive cars and travel by plane. Carbon Dioxide emission on the atmosphere is also caused by the burning of coal, oil and other natural gases. It is also possible to emit Carbon Dioxide when we produce iron, steel and cement and during waste combustion.

To prevent global warming, you can help by decreasing how often you drive. Less driving means less carbon dioxide emission from your car. By traveling less will also help lessen the emission of carbon dioxide in the air.

Get a car service on a regular basis. This will increase your fuel efficiency which eventually decreases your green house gas emissions. New car models are eco-friendly. They promote the use of biodiesel and others are hydrogen powered.

Cut back on your heat and air conditioning. You may add insulation walls to lessen air conditioning. Turn down the heat when you sleep or going out the house. Saving electricity will also reduce global warming.

Most importantly, planting a tree helps a lot. A single tree can absorb 1 ton of carbon dioxide for its entire life. Trees are important because they absorb carbon dioxide in the air and in turn give off oxygen.
