Clinton invested a lot of money into biological invasive species. 1st point can lead to bad ecosystem health. We spray pesticides to reduce the effects of pests on agri(cid:272)ulture. If (cid:449)e did(cid:374)"t spra(cid:455) the pesti(cid:272)ides, (cid:449)e (cid:449)ould lose 30% of yield, which is billions of $ of food.
