Climate change can be a seriously disaster to the earth, and It can cause damage to the environment. But people are still wondering who or what cause the climate change. The argument between human activities is or not a substantial cause of global climate change has ever been stopped. But nearly all climate change studies show humans as the main cause. Three key arguments will be support the suggestion that human activity is a substantial cause of global climate change.

It's the Deforestation
Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama is losing each and every year.
Plants and trees help remove heat-trapping carbon dioxide gas from the air by storing it in their leaves, wood and roots and soils. When plants and trees are destroyed, these stored carbon dioxide gases will released into the atmosphere, where it contributes to climate change. Deforestation and land use change contributes approximately 20 to 25 percent of the carbon emissions that cause the climate change.
According to the report published by the Oxford-based Global Programme, which shows that the rampant slashing and burning of tropical forests is second only to the energy sectors as a source of greenhouses gases.
It's the Greenhouse Gases
The greenhouse Gases is the most important factor cause of global climate change. The chemical compounds found in the earth’s atmosphere act as greenhouse gases. Some of them occur in natural, such as water, vapor, carbon dioxide, methane, and nitrous oxide, while others are exclusively human-made. The human actions cause mainly effect to the greenhouse gases. Human produced CO2 emissions by burning of fossil fuels in the past 20 years which will warm the earth. Rising temperature can produce change in weather, sea levels, and land use patterns, commonly referred to as climate change. Our greenhouses gas emissions come mostly from energy use. Theses are driven largely by economic growth, fuel used for electricity generation, and weather patterns affecting heating and cooling needs. Showing by the source from Energy Information Administration Emissions of Greenhouse Gases in the United States, the energy related carbon dioxide emissions, resulting from petroleum and natural gas, represent 82 percent of total U.S human-made greenhouse gas emissions.
The climate of north and south poles became more extreme, human can not adapt the summer to winter temperature, which are caused by greenhouses gases.
It's our treatment of Natural
Warnings about climate change been ignored for more than 20 years. Our treatment of natural is another main cause of global. People believe to be able to control nature instead of trying to arrange ourselves with the natural. This haughtiness is the true main cause of climate change. This haughtiness misleads us from treating the natural environments.
It is like having a wild party where we destroys beds, the kitchen as well as the living room of a hotel without ever thinking about our future staying in the hotel nor about other guests arriving later. People are just thinking about how to enjoy the happiness at the present without considering the serious consequences cause to the environment.
To Conclusion
People took 20 years to broadly accept that human activity is causing climate change with the emission of greenhouse gases. People believe that Climate change is part of natural. But human activity is accelerating and changing the climate change, this will cause unknown damage to our environments.
It is us our decision whether we want to be the cause of global climate change. However the three main substantial cause of global climate change are outlined in this blog.
