A crew on board a ship belonging to a nonprofit made an unusual discovery while cleaning trash out of the Great Pacific Garbage Patch, the largest collection of ocean plastic in the world.

At this point, we don't know what we're looking at.

The team recalled in an interview with the San Francisco Chronicle that when they stumbled upon what appeared to be "mysterious plastic floating objects," they referred to it as a joke.

The object barely fit into the ship's cargo hold. The team hasn't figured out what the hell it was because it weighed 3.5 tons.

The captain said it looked like a fiberglass or plastic tank from the fishing vessel.

200,000 Pounds

The huge web of fishing nets captured by the team poses a real threat to the marine environment.

Around 200,000 pounds of Garbage Patch plastic was hauled by the Ocean Voyages Institute. It's only a drop in the ocean if you will.

The patch covers an area larger than Texas.

It is growing quickly. There are between 1.15 and 2.41 million tons of plastic waste entering the ocean each year.

It's depressing to see how bad humanity has treated the oceans.

The founder and president of the Ocean Voyages Institute said that the ocean has been used as a garbage pail.

The Great Pacific Garbage Patch was swept up over the course of 45 days.

Marine scientists say pulling plastic out of the ocean is not worth it.
