This field/movement aims to reduce environmental exploitation (and thus negatively affecting plant and animal life, land degradation, water quality, etc) by large corporations and the government. The crux behind the movement (other than environmental ethics and concerns) is that disadvantaged populations (globally, too) are forced to bear the effects at significantly higher rates. These communities end up with more severe health outcomes from toxicant exposure, lack of clean water, etc.
Environmental justice activists work from and within these affected communities often to raise awareness of the issue, garner support, and work to create policies and action to reduce environmental injustices.
Environmental justice movements have stemmed from community organization. As a movement, environmental justice did not get attention (and actually did not occur) without affected groups of individuals rallying together to make it know the environmental injustices occurring. It is the vulnerable groups, when given the tools and support and movement from within, who can launch an issue into public domain and fight for their goal.
Individuals interested in community development and community organization who may be looking for jobs might find it ideal to look at the field of environmental justice. Frankly, there are so many environmental injustices out there in our country (and world), and people and communities are severely affected by them.
Environmental justice is a part of social justice.
"Cultural diversity thus becomes essential for biological diversity; and histories based on local economic development offer alternatives for the future that reflect values other than consumer lifestyles;a harmonious co-existance between social justice and environmental justice" (Ledwith 149)
Sustainable development now and in the future is going to NEED to employ issues of environmental (in)justice in its planning and execution, or society will continually be blocked from ethical just progress.
