I'm a veggie and am wondering if someone can remind me what are the negative ENVIRONMENTAL impacts of eating seafood and poultry (more so the seafood)? My girlfriend asked me this evening why I don't at least eat these two (for enviro reasons) and I couldn't even remember. I recall trudging (is that what it's called?), where they take the big nets and harm other water species when they're trying to harvest shrimp but that's about it. I still remember the deal with beef, and I know all the ethical arguments for all of it, but can someone please remind me what the ENVIRONMENTAL arguments are for not eating seafood or poultry?
