Sorry I'm changing my topic.
My new topic is about science and ethics. Although we say having curiosity is a good thing, this is not always true. There are some scientific discoveries that should not be used in our lives. For example, Einstein's curiosity created the atomic bomb which shouldn't have been existed. Scientists must think and imagine about the ethical problems of their discoveries, and the one's that might have bad effects to humanity should be banned like human cloning. So my thesis statement is "The use of some scientific discoveries that might have bad effects to humanity should be banned"
How about this:
返信削除"Scientific discoveries that might have bad effects on humanity should be vetted more effectively to determine whether they should be banned."
