Western Europe

Explanation:

The global environmental problems have been a raising concern over the past century. Lot of damage has been done to the environment around the world, so the alarm has been raised, and some regions started to act in a manner to protect the environment and improve its well-being.

Western Europe is a region that has initiated the large scale damage of the environment, as this is the region that started off the Industrial Revolution. On the other hand, this is also the region that has become the most aware of the dangers, so it is the first region that started to turn things around and make up for what it has done.

Multiple methods have been used in Western Europe as to how to solve the environmental problems, and a lot has been invested in those methods. Some of the most important are the strict laws that prevent the destruction of the environment, development of environment friendly and renewable energy sources, as well as cleaning up polluted areas and gradually converting them into forests or grasslands.
