1) government regulation
2) advertisements for environmental protection
3) environmental education in schools
I think the government regulation is most effective.
First, the government can force people to protect the environment. To be specific, through laws, the government can impose fines for people who damage the environment in a way like dumping trashes into lake. This forceful measure can actually have a big impact on people's actions.
Second, the government regulations can include a wide range of contents. There are many behaviors that can harm the environment. By documenting the detailed things about the environment in the law, the government can handle with various situations that can be detrimental to the environment effectively.
For these reasons, i think the government regulation is the best idea.
2. Some people believe it is better to get a university education after graduating high school. Others believe getting a job after high school is better. Which do you think is better and why?
I think going to the university is better than getting a job after high school graduation.
First, I can have a chance to learn about the world systemically. For example, I was a business major. Thanks to my major, i was able to figure out the international trade that was addressed by the professor. It helps me to understand the world better.
Second, I can meet many people who have various backgrounds. For example, when I was in the university, I was surrounded by many foreigners. Before meeting them, I used to have some stereotypes about foreign culture. But after hanging out with them, I could get to know the real aspects of foreign culture.
For these reasons, I think going to the university is a better choice.
