What is the subject of the documentary an inconvenient truth?

a: rachel carson’s research on the effects of ddt
b: al gore’s exploration of environmental law in the united states
c: rachel carson’s campaign to educate people about ddt
d: al gore’s campaign to educate people about global warming

Rachel Carson’s impact helped to quicken and conclude the ban of DDT that produced dangerous chemicals that killed a lot of living things, plants, bugs, animals and also affected people's health. As an impact it spread a disease among fish that caused it to die out and float on top of a lake, as well as the population of bald eagles drastically decreased as the DDT was in use, the ban of DDT promoted a sudden increase  in the population. DDT included chemicals that could cause dozens of diseases in humans as well such as cancer and kids started getting sick because of it. However what Americans can do to promote a safer and friendlier environment is to make a better recycling system and reduce the spill of dangerous chemicals out into the ocean and into lakes/rivers and other water sources. We can also narrow down to using way less dangerous chemicals and not ones like DDT for both the sake of the world around us and ourselves.
