Later

"We need to protect this species of fish. Too bad for the farmers - but they would not die. If they loss their job, just apply for unemployment compensation." Fans of environment protection argue.

And that's all I'm against.

Yes, that's how we treat dogs and cats and other animals. We provide food and a place to rest. That's all. But, is that how we should treat human beings ?

Imagine, if your government says to you, "We would not allow you to do this job. In fact, we need to make you unemployed for the coming few years. Don't worry, all your needs would be well looked after. We shall give you enough money to buy food, have a home, and so forth...", what would you think ?

What's the purpose of life ? Oh, I shall not discuss this very question. (I begin to develop a habit of avoiding discussion on important questions. That's no good, I know.) But, fans of environment protection - with the ultimate aim to make a better living of Homo sapiens, I suppose - should really study basic psychology and learn the Maslow's hierarchy of human needs.

"I shall deprive your need and return something else to you later ..."

We've been fooled too many times in our history by this statement. Don't do it again.
