Pollution of cars
I chose two pictures ,one is the car ,and the other is destruction .The connection of them is more and more cars cause big damages to the environment .Environmental problem is one of the most concern around the world .It is an important course that cars produce smog to aggravate the environmental pollution .
With the development of economy ,more and more family have cars of their own .With the help of a car ,we will able to get to any place we want .Nevertheless ,the pollution that cars bring us should not be ignored .Automobile exhaust contains carbon monoxide、sulfurous acid anhydride 、aldehyde、smoke dust and so on .A car will consume fifteen kilograms fresh air when it burns one kilogram gasoline .Cars have created a lot of serious problems in our world .All the time ,they are pumping huge amounts of waste gases into the atmosphere ,causing disease and even death They will form acid rain if many gases merge together .It will destroy the buildings 、the roads even people .
What should we do to decrease the automobile exhaust ?One possible solution is to invent and develop clean cars and clean fuels .In the world ,buses in some cities are driven by electricity ,while others begin to use natural gas .Another solution is to develop modern public transportation systems and restrict the use of private cars .We can encourage people to use bicycles .And we can implement traffic running .City population area ,with high traffic density ,vehicle exhaust emissions at a given time and more concentrated ,which causes the area at one time .The degree of air pollution will increase dramatically ,harm to human health .This can take the car stream running
From my point of view ,to protect environment ,the government must take even more concrete measures .First ,it should let people fully realize the importance of environmental protection through education .Second ,those who destroy the environment intentionally should be severely punished .We should let them know that destroying environment means destroying mankind themselves .
