Why would international communities work together to try to solve environmental issues?

it is a way to control a country with huge pollution problems.
it is much more expensive to work alone rather than together.
pollution in one country can effect other parts of the world.
pollution problems can be eliminated by working together.

Pollution in one country can effect other parts of the world.

"Pollution in one country can effect other parts of the world."

Explanation:

the natural environment. It can be the effect of a contamination, such as an oil spill in the ocean or the emission of toxic gases in the atmosphere. The human being is responsible for environmental problems. When the disorder occurs by nature, there is talk of a natural disaster (like the eruption of a volcano).

The failure in the Chernobyl nuclear plant that occurred in 1986 is a clear example of how human activity can cause serious environmental problems. The explosion in this nuclear power station released large quantities of europium oxide, boron carbide, uranium dioxide and other toxic substances that caused hundreds of thousands of people affected.

Actions such as the example occur all the time in different areas and with different levels of pollution, usually environmental pollution affects several countries or all, that is why work programs in environmental issues require the help of the largest amount of possible countries.
