DDT in very particular situations has also been a net positive. It's really the widespread indiscriminate use of it in nature areas and dumping it by the ton into municipal sewers that caused the terrible ecological outcomes. Similarly, organising ourselves into sprawling suburbs (rather than higher density cities with sparse rural communities and nature areas in between) was ecologically, the less optimal deployment of roads.
