Brazil has opened an investigation of the oil giant Chevron after a major oil spill off the coast of Rio de Janeiro. A well at a Chevron drilling site has released unknown amounts of oil into the sea. A top Brazilian police official called the spill an “environmental catastrophe.”

Fabio Scliar: “This is a great environmental disaster; no doubt this is an environmental catastrophe. This area is a migratory route where many marine species go by. The dimensions of the spill are much bigger than the company would like to admit.”
