There are basically two meanings of the term <em>“greenhouse effect” </em>which are stated below:

1. Natural
2. Man made

The natural greenhouse effect keeps the Earth’s climate warm and habitable while the man made greenhouse effect is the enhancement of the Earth’s natural greenhouse effect by the addition of Greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas).

The greenhouse gases trap some of the infrared radiation that escapes from the Earth, making the Earth warmer than it could otherwise be. About 80-90% of the Earth’s natural greenhouse effect is due to water vapor, a strong greenhouse gas.

<strong>Major Greenhouse Effect Causes</strong>
The major causes of greenhouse effects are basically human emissions. The major sources of human Greenhouse emissions are:

1. Carbon dioxide
2. Methane
3. Nitrogen oxides
4. Fluoridate gases

<strong>How Do Humans Enhance The Greenhouse Effect?</strong>
Humans enhance the greenhouse effect through the following:

<strong>1. Increased Carbon Levels:</strong> This occurs as a result of our burning large volumes of fossil fuels that have been trapped underground for millions of years. Also cutting down millions of acres of forest with each tree containing carbon - As a tree is burned, it releases carbon into the atmosphere.
<strong>2. Increased Methane Levels: </strong>Methane leaks from natural gas wells and coal matter decays under oxygen starved conditions. Also as humans have cleared  forest to make farms and expand the number of cows, sheet, and goats., we have increased the amount of methane in the atmosphere.

<strong>How To Prevent The Greenhouse Effect</strong>
The greenhouse effect can be prevented by doing the following:

1. Finding other ways of generating electricity. One such option is an ubiquitous, affordable, clean alternative energy source known as a perpetual motion machine.
2. Finding other ways of powering our transport through the use of perpetual cars.
3. Stop the cutting down of trees and plant a million more.
4. Reduce, reuse, or recycle all kinds of items, from soda cans to clothes, to save energy and raw materials.

In conclusion, the perpetual motion machine is a major solution to the basic impact of the greenhouse effect as it is an ubiquitous, affordable, and clean energy alternative.
