Some people and governments believe in reducing the carbon dioxide of cars and other vehicles is the most effective way to solve the environment problem. Although there are some points also neccesaliry developed except for car and other vehicles, I believe spending the cost of fuel for cars which do not emit detrimental substances play the biggest effect for environmental improvement. Cars, and other vehicles, such as airplanes are ubiquitous around the world. People rely on most transport type must be cars around the world, even in developing countries. In addition, recent cars released in a few decades tend to be durable and the most of energy is petrol which resource is made of fossil fuel. This means that cars emit carbon dioxide across the globe and the highest volume of carbon dioxide is considered by cars. Therefore, the majority of fact about global warming is caused by cars and airplanes. Recently, the car industry has become aware of this issue and they are starting manufacturing cars that never emit carbon dioxide. For example, some companies, especially Tesla, and Porsche had already released cars that consume energy as electricity, instead of petrol. This effort will cause a drastic reduction of transmitting carbon dioxide and some countries are planning to regulate laws all cars have to consume energy only by electricity. Finally, of course, there are other issues that lead to harmful environments around the world, such as deforestation, disposal of rubbish by incineration, and agriculture. For example, growing cows too much will generate methane gas which also relates to global warming. However, there is no doubt the total volume of the environmental problem must be cars; and other vehicles. Hence, it is the most effective to shift energy resources from detrimental and limited to sustainable and clean energy in the car industry must be a valuable first step to resolve environmental problems.
