How Do Humans Contribute to the Greenhouse Effect?

[linda]

The human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature. Let’s see how humans contribute to the greenhouse effect.

• Burning natural gas, coal and oil -including gasoline for automobile engines-raises the level of carbon dioxide in the atmosphere.
• Some farming practices and land-use changes increase the levels of methane and nitrous oxide.
• Many factories produce long-lasting industrial gases that do not occur naturally, yet contribute significantly to the enhanced greenhouse effect and "global warming" that is currently under way.
• Deforestation also contributes to global warming. Trees use carbon dioxide and give off oxygen in its place, which helps to create the optimal balance of gases in the atmosphere. As more forests are logged for timber or cut down to make way for farming, however, there are fewer trees to perform this critical function.
• Population growth is another factor in global warming, because as more people use fossil fuels for heat, transportation and manufacturing the level of greenhouse gases continues to increase. As more farming occurs to feed millions of new people, more greenhouse gases enter the atmosphere.
• Ultimately, more greenhouse gases means more infrared radiation trapped and held which gradually increases the temperature of the Earth's surface and the air in the lower atmosphere.

I'm not sure everybody knows there is a database of articles and blogs on EC too

Instead of worrying about how you add to the Green House effect check out the Carbon Offset link on the EnviroCitizen homepage. That way you can see what you're adding and how to reduce it!
