In some ways, I agree with the author, the current system is not sustainable. I'm against fish farms, especially the one that is in the picture, having visited it, and due to side effects such as pollution to the waters and to the environment. Although a fish diet may be recommended, and there are some people that may be allergic to it, the explosion in the population means any solution shall not be sufficient. Planet Earth, put simply, can no longer take it, humans are the number one polluters.
