Causes of Global Warming

Global warming is caused by many things. There are two main causes which are man-made and natural causes. One of the causes is greenhouse gases which increase the atmosphere’s temperature. The greenhouse gases come from the burning of fossil fuels . Carbon Dioxide and Nitrous Oxide and methane are greenhouse gases. There are many man-made causes. The first cause is that pollution,burning fossil fuels causes pollution. fossil fuels is made from coal and oil. When we burn they give off a greenhouse gas called CO2. Another cause is population. The population is increasing yearly so is the demand for food, drinks and transportation is increasing. It means more methane because there will be more burning of fossil fuel.Another source of methane is manure. By increasing the population we need more vehicles such as trucks and cars.
