Those "toxic" oil cleanup chemicals actually help coastal forests survive way better than if we just left the oil alone.

The Takeaway
A 40-year study of a Caribbean oil spill found that while dispersants initially stressed coral, they prevented the total collapse of mangrove forests. Because the trees were saved, the coastline remained stable; without them, the entire ecosystem would have eroded away, causing far more permanent damage than the chemicals themselves.
From the abstract
The TRopical Oil Pollution Investigations in Coastal Systems (TROPICS) study, initiated in 1984 on the Caribbean coast of Panama, sought to evaluate the comparative impacts of untreated crude oil versus chemically treated (dispersed) crude oil on nearshore tropical marine communities. The results broadly established that the impacts to mangrove communities from non-dispersed crude oil included significant adult tree loss, with long-term implications for substrate stability. Dispersed oil resulte
