It is not so much the eco-system, it is the need for a full food-chain of animals to keep populations in-check. We like deer but without wolves or large cats, the deer become a pest but we don't like wolves and large cats because we are all taught as children that they are scary and dangerous - although more children die from car accidents and stabbings than wild animals so whatever!
So natural predators for small rodents keep their numbers in check but that will be a long time because "won't somebody think of the children"..."and the farmers"

The error you make is that there is only one, global ecosystem, and it sorts itself out. We won't be matching the power of the dinosaur comet anytime soon, and even that gave rise to mammals and eventually space travel so just chill... We dont need to do a thing
Restored? What are the appropriate levels of "diversity"?
Some facts humans cannot handle:
- lifeforms suffer unimaginable agony every single day.
- life is finite
- humans are not beyond the natural order, human made global warming is natural, it won't end the planet or even us.
- humans think because suffering makes them sad, suffering must be the bad. (Apart from when we don't like the other person or they've transgressed us in some way, were ethically clear to mete out violence)
