Greenhouse Gas Emissions

I searched on the Google and knew that The Kyoto Protocol, is an international treaty among industrialized nations that sets mandatory limits on greenhouse gas emissions. Greenhouse gas emissions, such as carbon dioxide (CO2), which can trap additional heat from the sun in the earth’s atmosphere, causing the ‘greenhouse effect’ and climate change. CO2 is the main greenhouse gas produced by motor vehicles. 

In my opinion, climate change is real, accelerating and caused by human activities. Example, Our personal vehicles are a major cause of global warming. People can help by driving less. If have to get out ,you can try to choose walk, bike, carpool or use public transportation instead of driving or taking taxi.

Global Warming

In my opinion that humans are the cause of global warming.Records shows that  humans release around 37 billion tonnes of CO2 into the atmosphere every year . That is a huge amount. Most of which comes from the cars, the aviation industry, the shipping industry and in factories and power plants.

Recycling


In my opinion,recycling is very important to conserve natural resources. Example, to save water, firstly we need to reduce the consumption of water. like reduce using  laundry detergent, fixing leaky faucets, taking shorter showers etc.Secondly, used water from kitchen sink can be used to water gardens. Used showers, clothes washers etc can be used to flush toilets . In this way we would be saving gallons of fresh water from being wasted.

The graph shows that people perceive about global warming in American by IPCC Synthesis Report，Yale. Humans peak about 90% by percent of climate scientists who believe global warning is being caused by humans.There was about 70% by percent of Americans who believe global warming is very real.

The graph shows total annual greenhouse emissions by sector.There was about 21.3% by power stations.Waste disposal and treatment was about 4.3%.
