Is crude oil dangerous if added to the ocean?

Answer 1

I will rephrase your question a bit:

Do all crude oil spills impact the environment?

Oil occurs in naturally in the Gulf of Mexico and in the ocean, coming from oil seeps on the sea floor. The concentrations are low enough so the impact is minor.

Numerous oil spills occur every year with only minor impact to the environment. Some oil is spilled when tankers complete their loading or unloading. The environmental impact in these cases usually minor.

When large quantities of oil are spilled into an ocean, the environment is harmed and a dangerous condition exist for boats in the area.
