Lol well played playa. Thats what i mean, there's far fetching impacts that we're unable to see every time we alter the ecosystem.bad point. the ecosystem is just that, a system. when you change one thing you change others you have no idea of.
for example, over fishing of salmon slows the growth of many of our old growth forests.
less salmon, less fish for the bears to catch during spawning, that's less fish carried into the forest to be eaten, with the bears leaving less because now they can't just eat their favorite parts and leave the rest to fertilize the trees. they also don't go off into the woods as far, so that reduces the area fertilized as well.
and that's a fairly direct one.
you have no idea of the impact of these kinds of things because you can't see everything that's being impacted. so what if half the fish in that lake don't belong there? maybe the heron that can't catch dinner now because the new fish don't taste good, or have spines and can't be swallowed. perhaps it's that endangered newt species that doesn't breed in that lake anymore because the invaders are better hunters, or don't fall for the tricks that the newt has evolved to escape a certain kind of fish that wasn't able to compete with the introduced fish.
so now what simply appears as a new fish on the line every now and then we have an extinct bird, an extinct newt, and who knows what else.
