Effects ...

Some gases in the atmosphere; called greenhouse gases, trap heat before it escapes to space. This is a natural effect to keep the Earth, and us, warm. Greenhouse gases naturally occur in the atmosphere but some of these gases are human made and are one of the strongest effects to the environment. These human effects are from factory wastes which are thrown out in rivers, seas, or in some cases kept in a disposal area on the surface of the earth. These wastes can cause infrared radiations which warms the earth’s surface and thus the atmosphere. Many scientists are concerned that this will trap more heat and raise the Earth’s temperature. Consequently sea levels and temperatures will rise. Other predicted changes in weather patterns are likely to cause more severe droughts and floods and higher rainfall intensity.
