The correct answer to this open question is the following.
Due to the high level of damage to the environment, both regions, Europe and Asia are taking drastic measures to reduce the impact of pollution in nature.
In Europe, the European Union legislation is focused on clean air and reducing the impact of global warming and climate change. There are first-world countries such as Swiss, Sweden, Denmark, and Norway that are relying more and more on electric cars. More people are using bicycles to ride short distances and are leaving the car at home.
Transportation systems in these countries are very modern and are great substitutions for cars.
European legislation is acting strongly against industries that pollute the air and the water,
The case of Asia is different. Although Asian governments are concerned with the damage to the environment to had not been able to act as swiftly as European nations. We have to say first that cultures are different are priorities too. In some Asian countries such as China, industries generate big income, no matter they pollute the environment
Asian nations have legislation to protect the environment but the difference with European legislation is that in Europe they enforce the law. In Asia, law enforcement is not as harsh as it could be regarding the protection of the environment.
Waste disposal is a major problem and is not s well managed as in Europe.
Although in 2014, China "declared war on pollution," legislation has not been enough to see important results. China is one of the countries that produce more pollutants in the world.
