I ACCIDENTALLY ANSWERED FOOD APARTHEID ON THE ENVIRONMENTAL JUSTICE POST. Environmental justice is as followed:
"Environmental justice is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies" -US EPA
Many times people are disproportionally impacted by historical and systematic racism and classism. This can make it harder for people to earn money, have access to education, and healthy food.  Lower-income areas are more likely to be targeted for less safe jobs such as coal plants. The point of environmental justice is to help diminish these gaps between people and help place laws to help protect those who need an equal opportunity.
