GLOBAL WARMING

Global warming is an increase in average temperature of the earth’s surface. It occurs by an increase in certain level of gases like water vapor, carbon dioxide, methane, which are present on the earth’s atmosphere, which are termed as green house gases and this phenomenon is also called as green house effect. These gases play a vital role in keeping the earth’s atmosphere warm by capturing or blocking the infrared energy from escaping into the space. As the greenhouse effect increases, there is an increase in the global warming simultaneously.

 

The main causes of global warming are:

There are two main factors which are responsible for global warming. They are as follows:

• Natural causes (or) nature causes of  global warming

                                          and

• Non natural causes (or) manmade causes of global warming.
• Natural causes  of  global warming

 

This includes all natural factors like:

1. Volcanic eruptions: Large amount of volcanic eruptions increases the earth’s temperature, causes harm to plants and damages environment by releasing toxic gases.
2. Earth quakes: By this factor, lands get disturbed and it results in destroy of vegetation.
3. Carbon dioxide: As the temperature rises, there is an increase in the ratio of carbon dioxide gas in air, which results in the melting of  ice bar, especially in northern hemisphere like Himalayas .

These factors results in an increase in earth’s temperature, which effects global warming. These factors include:

• Burning of woods, plastics, wastes, cutting of trees and forests (deforestation) to improve the livelihood.
• Fuels released from vehicles and industries, releasing of ethanol gas, etc.

 

Preventive measurements / precautions taken for protecting earth from global warming

• Trees play an important role in reducing carbon dioxide gas in atmosphere by the process of photosynthesis, so stop deforestation and plant more number of trees.
• Introduce the system of recycling and reduce the use of plastics.
• Control  or balance the rise in  green house gases, as they keeps the earth’s temperature warm by absorbing infra red radiation and prevents it from escaping in to the space.
• Regular emission tests for vehicles and chimneys of industries, to reduce the amount of carbon and other gases released.
• The use of renewable resources or renewable materials like solar cookers and bio gas for cooking, use of bio fuel, bio plastics, bio mass products and other renewable sources, which are produced from natural resources, can be used to prevent pollution.

 

There are several small steps or precautions to protect earth from global warming and save the nature. Many animals and birds like sparrow have become extent, so come forward let’s join our hands in protecting our planet earth and other creatures from getting extent.
