The Great Pacific Garbage Patch, also known as the trash vortex, (collection of marine debris in the North Pacific Ocean) marine debris is litter that finds its way into into seas, oceans, and other larger bodies of water. The Patch has ballooned to twice the size of the Continental U.S. Plastic waste has become one of the most significant sources for marine pollution. The garbage patch spans waters from the West Coast of North America, to Japan. The patch is composed of the Western Garbage Patch, which is located near Japan, and the Eastern Garbage Patch, which is located between the U.S. states of Hawaii and California. The patch expands 500 miles off the California Coast, past Hawaii and almost as far as Japan.

90 percent of debris floating in the ocean is plastic, which is an immense problem for animals who get their food from the ocean. Every square mile contains 46,000 pieces of garbage. Fishing nets and other debris like footballs and bottles collude together creating large underwater masses.

No matter where the large masses of trash end up, it always ends up getting in the way of wildlife. They tend to start eating the trash which isn’t always just bits and pieces, a lot of it is whole bottles and other large debris. The large masses of debris in different areas are coupled up. About one-fifth of the trash is thrown off ships or oil platforms, the rest comes from land.

Lots of the Garbage Vortex gets fermented into smaller pieces as it moves about. Algalita, the Marine Research and Education Organization trawled a sample of the patch so see what it consisted of and this is what they found after a mile of trawling

The amount of debris stockpiles because most of it isn't biodegradable. Plastic doesn't biodegrade, it just breaks down into smaller pieces. 70 percent of the debris in the ocean sinks down to the bottom.


Every year hundreds of millions of broken up pieces of plastic are dumped into or lost at sea where they eventually make there way into the food chain where they act as sponges for a mixture of anthropogenic chemicals (carbon dioxide in the atmosphere that is created directly by human activities)

Charles J Moore, an oceanographer, and racing boat captain discovered the patch in 1997 Charles and his crew members were sailing back from Hawaii after placing 3rd in the "Transpac Sailing Race." They ended up taking a shortcut to Los Angeles by going through the "North Pacific Gyre" and discovered how bad the trash vortex was, which is twice the size of Texas.

Age of fish and amphibiansThe Denovian period of the Paleozoic Era, "Age of fish" lasted from 417 million years ago to 354 million years ago. Amphibians have been around for 350 million years . The first frog sighting was about 190 millions ago during the late Jurassic Period.

During the Denovian period plants had progressively grown. Earth's first forest was created by Lycophytes, horsetails and ferns that grew very large. At the end of the Denovian period Progymnosperms were the first successful trees with a 3 foot trunk, sprouting about 98 feet in the air. Also at the end of the period the proliferation of plants increased the oxygen content of the atmosphere which was very important for the development of terrestrial animals.
The climate during the Devonian period was very warm because it was close to the equator which made plants li
