MSNBC host Chris Hayes interviewed journalist Antonia Juhasz Saturday morning about the damaging results two years after the BP oil spill into the Gulf of Mexico.

Juhasz, who wrote the book Black Tide based on the many problems after the spill, highlighted key elements that have been overlooked by media outlets not covering the story closely since its early high volume of attention.

"The most important is that this is an ongoing tragedy," Juhasz said. "The consequences began on April 20, 2010, and continue aggressively today, and we can expect them to continue aggressively into the future."

"We've seen enormous harm to the fish species and sea life that try to live in the gulf. We've seen entire species where there is concern that they won't come back. Enormous declines in the availability and production of shrimp, of clams, of oysters, of all the seafood, which of course impacts fishers."

Juhasz added that the spills are similar and could surpass the damage from the 1989 Exxon-Valdes oil spill in Alaska.
