Socially responsible investing is a good thing in small does, but if all investors become socially responsible, staple industries will suffer from a lack of funds leaving the world economy in ruins.

这段话其实有两个论点，but之前是一个，but之后是一个，大家怎么看这两个论点呢？应该从哪些方面来说明自己是同意或者不同意这两个论点？谢谢。
还有，请问哪里可以找到一些关于“社会责任投资”的学术文章，谢谢了。
