The DoDo is extinct and I'm fine.
The Tazmanian Tiger is extinct and I'm fine.
The Ivory Billed Wood Pecker may or may not be extinct, either way I'm fine.
Aldo Leopold said it best: "The first rule to intelligent tinkering is to keep all the parts".
Do we need the Dodo? Apparently not. Are you smart enough to know exactly which species we need and which ones we don't?
The yew tree (pacific northwest conifer) was pretty much a "garbage" tree. Then someone discovered it produced an ingredient effective in fighting childhood leukemia. Suddenly, biologists were scurrying to find it. After a time, the chemists were able to duplicate it. HOWEVER, without that original blueprint, the search might never have found it. Is every species going to have such a story? Probably not (though a surprising number DO.. there is good reason why pharmaceutical companies have been sending biologists and anthropologists to remote regions in search of new plants). The point is do you know
which ones we can safely eradicate?
Also, remember this. The ocean is huge. You may dismiss "a bit of fish for supper", but many people, whole cultures and societies depend upon our ocean. Collapse of fisheries would devastate world economies, make no mistake. Collapse of even certain segmants has had phenomenal impacts on societies already. And, stocks are in far worse shape than most people want to realize. Fish keep coming to market because fishing techniques get better and better, but the ocean doesn't produce more. Farming fish in the ocean works in some instances, but has its own problems.
Finally, when we talk about the ocean, we should really be talking about the world's water. Every pollutant on land, every mineral, etc. all wind up in the water eventually. For reasons that take some explaining, aquatic animals are usually far more sensitive to these things than us. If it hurts the fish, it might not hurt us YET, but it will, in time. Fish, our streams are "canaries" for the world.
