What is environmental justice?
Environmental justice means two things. First, fair share: no group should suffer much more pollution than others because they are poor or have less power. Second, fair voice: everyone affected should be heard before a factory, dump or mine is built near them.
Pollution is any harmful change to air, water or soil. A polluting industry gives off a lot of it, such as a chemical plant, a tannery or a coal power plant.
Why do polluting industries move?
The cause-and-effect chain you saw in the 3D is:
- A place makes strict rules (laws to limit pollution).
- Cleaning up becomes costly for the factory.
- The firm looks for a place with weak rules, low wages and cheap land.
- It moves (or sends its dirtiest work there).
- The goods are sold back to richer buyers.
Some researchers call this idea the pollution haven idea. Evidence shows it is not the only reason firms move, but it does happen for some dirty industries.
Who is harmed?
The harm usually falls on people who have less money, less information and less power: poor neighbourhoods, minority groups, tribal communities and workers. They can breathe unsafe air, drink polluted water, lose farm land and fall ill. They often cannot afford to move away or go to court.
This idea is also called the NIMBY problem: 'Not In My Back Yard'. Strong communities can say no, so the dirty site ends up near weaker ones.
Cases to know
- Bhopal gas leak, India (1984): a pesticide plant leaked poisonous gas. Thousands died and many more were harmed for life. People lived very close to the plant and had little warning.
- E-waste: old electronics shipped to scrapyards where workers burn and dissolve parts in unsafe ways.
- Ship-breaking: old ships are cut up on beaches in a few countries, with little safety and spills into the sea.
- Waste dumping: toxic waste sent to places that cannot treat it.
Think about it: who made the profit in each case, and who lives with the harm?
What are fair solutions?
- Same strict rules for everyone, and global agreements (such as the Basel Convention on hazardous waste).
- Polluter pays: the firm pays for cleaning and for damage.
- Cleaner technology and recycling in the home country.
- Honest information and a voice for local people before building, and the right to go to court.
- Buyers can help: choose products from firms that follow high standards everywhere.
Try it: look at a product at home and find where it was made. Ask what rules might apply there.
Key formulas and definitions
- Key terms: environmental justice, pollution, strict vs weak rules, polluter pays, NIMBY, e-waste
- Cause chain: strict rules â higher cost â move â harm to local people â goods return
- Fair share + fair voice = environmental justice
Worked examples
1. A dye factory in a city must now treat its waste water, which costs a lot. It opens a new plant in a poor district where checks are rare. Explain what has happened in terms of environmental justice.
The factory moved to avoid the cost of strict rules. The district gets the pollution but may have little power to object, so the burden is unfair. This is environmental injustice.
2. Why can people who live near a polluting factory often not just move away?
They may not have money for a new home, may work in the factory itself, or may have no other land. So they stay and bear the harm.
3. Name two things a company can do to be fair when it builds a factory near a village.
Share honest information and ask the village before building, and use clean technology with the same standards as at home. Paying for any damage also helps.
4. What does 'polluter pays' mean?
The company that causes the pollution pays for the cleaning and for the harm, so the cost does not fall on local people.
5. Why is it unfair if rich countries send old phones to poor countries for recycling?
The recycling can be done unsafely, harming workers and children, while the benefit of using the phones was enjoyed elsewhere. If it is done safely with fair pay, it can be fine.
6. A town with strong residents blocks a new waste dump. A poorer town gets it instead. What is this called, and why is it a problem?
It is a NIMBY outcome. The waste does not disappear; it moves to people with less power, so the harm is shared unfairly.
Common mistakes
- Thinking environmental justice only means 'protect nature'. It is about fairness to people too.
- Believing every factory that moves does so only because of pollution rules. Wages, land and markets matter too.
- Thinking the problem is solved when the air in the first place gets clean. The harm may just have moved.
- Forgetting that local people need a voice, not only protection from others.
