Consequences of the Environmental Degradation Do Not Respect National or State Boundaries. Explain.

Yes, it is true to say that the consequences of the environmental degradation do not respect national or state boundaries.

For example: If any country or state causes air pollution then it will affect not only to that state or country but to all throughout the world.

If there is water pollution caused by any state/ country then it will affect all states/ countries through which the river is flowing.
