The earth is the only planet where life exists including human beings with almost billions of population all over the world. The generation is growing such faster and more powerful that the technology has become increasingly popular and more important to the world. But there is a problem "The global warming", an important issue in the present world. It is said that "one day the earth will be destroyed by the global warming". The increasing population with the demand of the resources is continuously becoming a hazard for the world along with the more and more technology that we need in the present world. These is leading to the increasing pollution of air, land and water, these affects the environment making the earth hotter that is the global warming.

ANSWER

Here is a short speech on global warming hope it helps you.

Global Warming occurs as a result of increased concentration of greenhouse gases in the atmosphere. The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. These gases do now allow all the radiations from the Earth to escape back info space. This is known as theGreenhouse Effect. This trapped radiation or heat helps to keep the Earth at a constant temperature. Greenhouse effect is thus very important to main the temperature of the Earth at a habitable level.

Over the past few 100 years, human have been burning trees and fissile fuels, thereby releasing millions of tones of carbon dioxide into the atmosphere. The increased level of carbon dioxide in the atmosphere has caused the temperature of the Earth to rise. This, in turn, causes more water to evaporate into the atmosphere. Water vapor is also very good at absorbing heat. This cause the Earths atmosphere to become even warmer. Scientist has called this effect Global Warming. They have warned that Global Warming could shift rainfall patterns, raise the sea level and alter the ecological balance.
