"like introducing invasive plants with known anti-parasitic properties to foraging ranges"
Completely off-topic now, but what about suffering of parasites themselves in presence of those plants? Why do people care about cute animals and not about and often at the expense of less cute ones? (that's a rhetorical question, because they are cute duh)
We can't make things better for some living organisms without destroying others. Since there is no objective way to weight outcome of an intervention, we can't "maximize global animal welfare". Most of the time it will benefit one fluffy thing at the expense of another, usually less fluffy.
Undoing results of our own actions is a defensible thing though. As is maximizing some kind of utility to us, for example working to increase or maintain biodiversity to avoid being next extinct species on the list. But biodiversity just means shitty life for more kinds of animals as far as maximizing animal welfare goes.
