climate change

"Climate change is the most severe problem that we are facing today, more serious even than the threat of terrorism."

David King

effects of global warming

• Increase of temperature on the earth:
• Changes in temperature increase the frequency and intensity of some severe weather events, like floods, droughts and tornadoes.
• Lower agricultural yields and species extinctions are caused by Global Warming.
• Rise of sea levels:

Sea levels are rising due to thermal expansion of the ocean, along with melting of land ice.
The total power of cyclones has increased noticeably because their average intensity and duration have increased.

causes of global warming

Natural Causes

Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

what should we do

As a nation, we are attributed as the leading cause of global warming, with the most greenhouse emissions anywhere in the world. In addition, as the most influential country in the world, we can choose to sit by and watch it happen, or we can decide to become a more environmentally aware population, setting an example for the entire world to see. The debate of the causes of global warming should not matter, because the fact is that we are contributing to global warming through our activities, adding on to any natural climatic phase that the earth is experiencing. By not releasing so much greenhouse gasses into the atmosphere, we can end the global warming scare, and end the most debated environmental topic of the world today.

importance of trees

Trees are the great provider and protecter.Their services are many.
 they help preserve our species.in more way than we can imagine.
 A poet says
              woodman spare the tree,
                touch not a single bough,
                in youth,it sheltered me,
                And I'll protect it now

pollution

we find the atmosphere and water increasingly polluted in the cities. our modern civilization is responsible for the pollution in the atmosphere.we destroyed the beauty of nature because of this pollution and this pollution  made many changes in our enviorment that would be dangrous for us
