Lower order edibles like what? how low are we talking? you can't live off of algae alone. I think i get the gist of the question though. lower order plants and animals replicate fast and are abundant. removing large chunks of them does not hurt the viability of the food web. if you start taking out higher level organisms like primary of secondary predators though it is very easy to loose the controls on the underlying system. if i eat a chicken (free range of course) i don't have a big impact on the environment because there are a lot of chickens. As for health, toxins are concentrated the higher you go up the food web. That's why it is not recommended that you eat tuna more than once a week
