The world starts to quickly realize gasoline and/or gas is a harmful fuel, which produces most of the emissions which polute the environment, and star using electric cars. Which apparently are emission free. But once ppl get used to driving said cars, and star wearing them out, along with their batteries, they start realising that electric cars aren't as eco-friendly as they where lead to believe. Producing most of the battery components in various countries generates environmental impact by having to transport them to a central place to actually produce the batteries, whose life is of about 5 years, depending on use. And once the batteries wear out, they have to be changed, producing an even greater impact by being disposed into landfills. Ppl then start believing, finally, that Hydrogen cell cars are a better option.
I wish I were home, and eating. Right now.
