That kind of argument seems to presuppose that humanity is distinct from nature. It's not unique in that, of course; lots of things people say presuppose that humanity is separate from nature, so in that sense, it's a perfectly ordinary argument to make. On the other hand, I personally think of humanity as a part of nature like any other, which makes those sorts of arguments seem odd to me.
Some people might argue that any type of "intervention" alters Nature's equilibrium. But I guess I would have done the same, if I were in your shoes.
