The great causes of environmental pollution are cars' exhaust smoke in the atmosphere, sewer discharges to the sea, industrial smoke, forest fires and soil pollution.
The greatest consequence is global warming.
To prevent it, I would choose some measures like building sewer treatment stations, forest surveillance systems and keeping them clean to prevent fires, avoid dumping chemical products on the soil.
Protect the environment because we won't live without it.
