Spreading of TOXIC materials throughout the EARTH affecting POLAR BEARS

Polar bears are facing a lot of problems due to human activity. As we have increased the emission rate of greenhouse gases into the atmosphere to a greater extent, the polar bears are the most affected by it. We not only pollute the air but also the water. These toxic and hazardous materials travel the source to the destination with either air or water as the medium. Here the source is the place where the toxic materials are being produced or emitted like industries, automobiles, etc., and the destination is the place or things that are being affected by it like various habitats, vegetations etc.

Polar Bear baby died and parent is crying!!!

Mainly the polar bears in the arctic regions are face hard time due to these toxic materials. They are being affected by different kind of infections. They are losing their weights, resistance to cold, some even lose their lives. If this emission continues and increases, then in few decades one won’t find any polar bear left on this earth. So one by one we will lose everyone starting from the polar bears till ourselves, if we don’t take any proper action regarding our emission.

By controlling our emission we can still save the other polar bears left. It is never late to act. Everyone has to do their duty properly. Everyone has to contribute inorder to achieve this success. As drops of water put together makes an ocean, likewise everyone’s duty can save our earth and natural resources.

GREATEST EFFECTS OF GLOBAL WARMING CAN BE FELT BY SMALL VARIATION IN THE GLOBAL TEMPERATURE

Humans have exploited the earth to such an extent, that from now onwards even if the average global temperature increases slightly, its effects are going to be worst.

Effect of global warming is  almost similar to the rubber band that has lost almost its elastic property & even a small pull from now will break it.

There is an average increement of around 2 degree centigrade of average global temperature. As the human exploitation is going on a rapid rate, the average temperature might increase to even 4 degree centigrade very soon.

This in turn will increase the amount of carboin dioxide in the atmosphere. Increase in concentration of carbon dioxide will lead to global warming & the chain of environmental problems continues.

The humans are not aware that they are also being affected indirectly by there activities. 

For example:

1. Due to excess of pollution the average human life span han gone down considerable. He is dieing very quickly when compared to the previous generations.

2. Due to their activities lands get submerged under the oceans which again affect them.

So nothing is late, just come together & help to save our earth & natural resources.

CONTRIBUTION OF OIL SPILLAGE TO ENVIRONMENTAL PROBLEMS

• Oil spillage has various adverse affects on the living organisms on this globe. 
• The affects may be classified into two main categories
• Short term
• Long term
• Source for this oil:
• Damaged oil tankers
• Damged pipelines
• Many other human activities
• Effects:


• Marine eco-system is hamppered
• Damages beaches, marshlands
• It enters the food chain and remains for long period in this globe affecting various living organisms
•  
• What happens when oil spills?
• The main thing is that it will act as an covering sheet over the ocean or any water body, which wont allow the sun rays deep into the water body.
• This in turn will cause death of various marine flora & fauna which are at the deepr part of the water body.
• These dead matter will increase in the water body which absorbs ample amount of oxygen & liberates carbon dioxide in the water.
• Therefore due to lack of proper oxygen supply the whole marine ecosystem will be disturbed greatly.
• Along with this, the birds, animals & humans who consume such affected products will thus be affected. This will continue in the food chain, there by causing huge loss.
• This way we will lose various ecosystem, rare species, beaches etc.
