Ladies and gentlemen,
Good morning. Today I want to talk about the issue of electric cars, but first, I’m going to begin this presentation with a deep question —‘Have you ever heard about the environmental damage caused by the exhaust gas from fuel cars?’—Well, I’m sure there are a lot of people, like me before, who don’t pay attention to this issue. But recently I heard a heartbreaking news reported by The Guardian which may helps you changes your mind . It is said that the rapidly melting glaciers in the arctic could wipe out more than a third of polar bears over the next 45 years as greenhouse gas emissions from fuel cars intensify. These terrible figures show the great harm done by automobile exhaust emissions and I believe it strongly shocks all people who have a heart.We all know that carbon dioxide emissions from gasoline cars are responsible for the polar bear’s bone-thin demise .So,how can we save the poor polar bears ? Of course the answer is electric cars .In my opinion, pure electric vehicles use electric energy, there is no exhaust gas emissions in driving, and no pollution to the environment.Therefore,My friend,this is why we must vigorously develop and promote electric vehicles.It is not only conducive to protect the polar bears I told you about,but it also contribute to the our air quality and physical health .Thus,I am firmly convinced that we should set a target of 50%electric cars by 2030 because it benefits everyone involved.
The first thing that is coming through my mind is the electic cars help protect animals.
Let me move to my second point.The elecric cars will influence air quality and the prevalence of people. The electric vehicles adoptions reduces net carbon emissions and has the added benefit of reducing air pollutants, thereby improving public health.Just like Daniel Horton, the senior author of the study and an assistant professor of Earth and planetary sciences at Northwestern University, said” the more cars that transitioned to electric power, the better for summertime ozone levels,the more combustion cars you take off the road, the better the ozone quality.”In fact,air quality is associated with the resolution of a variety of health problems, such as asthma, emphysema and chronic bronchitis.For example,
the National Academy of Sciences found that air deaths from pollution could be reduced by 70% when electric cars dominate the market, and can use renewable sources of electricity, such as solar, geothermal or hydrological power.Therefore,to improve air quality and control diseases,I believe that a target of 50%electric vehicles would be a necessity .
