This was a interesting work. When I was looking for social advocacy issue, our instructor taught us that we could make this kind of issue into concrete work. Then, I found an article that was talking about electric car’s crisis because we are using lithium-iron as main batteries in electric car which is extremely toxic and pollutant material. Besieds, the mass production of lithium-iron batteries are still finite and in limited supply around the world. That is to say, people still use conventional vehicle as their main transpotation.

So, I choose a concrete outline of car and put this article into it.
