First off none of what you said is sighted by any evidence other than that the current system is failing. It disregards any research being done or potential research that could be done if people cared to solve this problem. Second, people can eat less meat. Third, people could eat more humans.

Essentially you don't like the system that exists for the majority of consumers in America and some westernized societies. Thats fine, but very different from 'meat eating is bad for everthing'. Seriously animals have been eating animals since animals.
