Do cows pollute the same as car ???


                      
                        In human daily life is responsible for an estimate 14percent of the world’s greenhouse gases. The emissions come from methane, which contribution to global warming, and it’s more powerful then carbon dioxide. On the other hand, the world’s 1.5 billion cows and billion of other animals emit dozen of polluting gases, it’s includes lots of methane. 2/3 is come from ammonia of cows. Cows emit a massive amount of methane from their belching with the lesser amount through flatulence. Some scientist had say that cows produce 100lt to 200lt a day (or about 26 gallons to about 53 gallons), while other says 500lt per day. Moreover, cows, goats, sheep and several other animals that belong to cause pollute to the atmosphere are called ruminants. Ruminants have 4 stomachs and restore their food in their stomachs instead of intestines, as human do. Ruminants eat food, and belch it as cud and eat again. This effect on atmosphere that stay nearby and it will send to the hold atmosphere that causes pollute of environment. For instance, Britain, cows contribute 3% of overall greenhouse gas emissions and 25 to 30% are come from gases in livestock.

Acid Rain....???


                       
Forest that cause by acid rain  Acid rain is referring to a deposition of wet (rain, snow, fog, etc) and dries (acidifying particles and gases). Acid rain cause by chemical forerunners of a rain formation result from both natural sources. Acid rain includes sulfur dioxide (SO2) and Nitrogen oxides (NOx) from human sources, such as electricity generation, factories and other vehicles. Coalpower plants are the most pollute to create an acid rain. The gases of these power plants are carried hundreds of mild in the atmosphere before the created acid rain. Moreover, the smoke of human vehicles such as car, motor, ship or train, etc. This smoke is polluting the atmosphere everyday of human life. The smoke of this vehicle will combine together and then it will become an acids rain that effect on human health. On the other hand natures are also cause an acid rain, especially volcano. The smoke of volcano will produce acid gases to the atmosphere, and it will cause an acid rain. To conclude natural disaster and human created are the most things that pollute the atmosphere of the earth and it’s become the acid rain.

Mekong River.....

In English it’s called “Mekong River”, derive from “Mae Nam Khong.” Mekong River is the world 10th longest river. Mekong River located in Asia. Mekong River is the 7th longest river in Asia. This river run through in 6 countries and also includes Cambodia. The countries that Mekong River runs through are China, Burma, Laos, Thailand, Cambodia and Vietnam. The estimate length of the River is   4,909km (3,050mi). People in each county need this water for their economy or their business. Moreover, in Cambodia Tonle Sap lake was a part of Mekong River system. In dry season, the water in Mekong River drains by Tonle Sap Lake and in rainy season the high water of Mekong River has flow to the Tonle Sap lake and increase the size of the lake. This both lake and river is very important for people in Cambodia.

Antarctica Face Global Warming..!!



                Antarctica now is in danger of global warming. According to scientist, “a common public perception is that global warming will accelerate the melting of polar ice sheets, causing sea level to rise.” Moreover, people around the world have known about North Pole and South Pole. South Pole is the coldest place in the world. Antarctica is one of the continents in South Pole. Nowadays, Antarctica is in global warming that causes many issues around the world. The layer of the earth is getting thinner than before because of human activities. When the layer of the earth is thin, the solar of the sun can easily go through and make the ice melt. The most common thing that cause the global wariming  is that the volume of grounded in Antarctica is growing slowly, so it can effect on sea level. According to the book (Concept of today) they said that “when the ice in Antarctica is melted, the sea will raise more 200ft, and every country around the world will face with problems.”
