Hi,

Hope you are doing great.

Environmental justice is a movement to ensure that no people will get suffer from the inadequate fresh food supply, an unsafe environment. It is related to the fair treatment and involvement of all the people regardless of race, color, income with respect to the implementation, development of environmental policies and laws.

The concept of environmental justice originates in the 1980s.

One of the examples of environmental justice is inadequate access to healthy food to certain communities that have low income or belong to minorities. Another one is air and water pollution, many of the commodities like minorities or low income live near the industrial plants, water disposal sites then the air and water qualities will definitely gonna suffer if they are not properly maintained.
