The world has had success with eliminating CFCs from refrigerants, banning leaded gasoline, eradicating iodine deficiency, dramatically increasing crop yields, eradicating polio, scaling up electrification, plumbing, internet access, etc etc. The idea that we can set a goal like this is completely conceivable. A lot of the low hanging fruit involves banning the use of antibiotics on healthy farm animals, and at least with the largest producers who raise and slaughter the majority of animals I think this could be achieved.
