primary reason for global warming is human activity that release carbon dioxide in the atmosphere. The reasons areDeforestation
Burning plastic papers or plastic products
Even the Air Conditioners also emits carbon-di-oxide which contributes more to global warminWe do not have a way to get back the rain forest, the land that has been taken to build new homes, and a way to dispose of all the natural waste that is produced. Many places dump this out in the ocean which is destroying the water and cause problems with the coral reefs around the world. If this does not stop there won't be much left for anyone.Global warming is one of the most serious issues facing the human race and the honest truth is that humans have a negative impact on the environment. Some of the ways we kill the environment include:
Clearing and burning of forestland.Burning of forests is harmful to the environment.When vegetation is cleared or removed,carbon is released back into the atmosphere as CO2 and this contributes to global warming
Ranching is also a culprit.Ranching produces a huge amount of animal waste which produces lots of methane...a harmful greenhouse gas
Fertilizers and pesticides also pollute waterways and air.They are manufactured at huge plants which dumps harmful chemicals into the environment including CO2 and methane.
Aerosols are also terrible for the environment.They are loaded with chlorofluorocarbons which heat the ozone layer and allows harmful UV rays activities that are responsible to generate green house gases including carbon disk oxide, methane, etc may cause global warming. The activities may be natural or anthropogenic. Other than fossil fuels, the activities may be automobile exhaust, volcanic eruption, deforestation etc. Through automobiles exhaust direct CO2 is not generated but CO is generated. With the reaction with atmospheric oxygen, the carbon di oxide is formedthroughg.
