Global warming is considered an earth killer. And one of the reasons that results in the global warming is greenhouse gases which result from emissions. Those car companies not only sell cars to people but also damage our earth. The 700 million cars currently on the worlds roads produce 2.8 billion tons CO2 annually. This represents 20% of the worlds CO2 emissions.
