Final answer:
The five main causes of environmental inequity include unequal wealth and power distribution, systemic racism, lack of political representation, historical location of industrial sites in less affluent areas, and the global economic system's impact.
Step-by-step explanation:
The five main causes of environmental inequity can be attributed to a range of social and economic factors. Firstly, the disparities often originate from the unequal distribution of wealth and power in society, where those with more resources can influence or avoid living in areas affected by environmental hazards. Secondly, systemic racism has contributed to marginalized communities facing greater exposure to polluted environments. Thirdly, there is often a lack of political representation or voice for lower-income and minority groups, leading to less attention to the environmental issues they face. Fourthly, the historical location of industrial sites in less affluent areas has meant that these communities have a disproportionate share of environmental burdens. Lastly, the global economic system, which prioritizes growth and profit, has led to environmental degradation that disproportionately affects poor and marginalized groups around the world.
