British environmentalist David de Rothschild's eco-friendly catamaran, the Plastiki, made from 12,500 reclaimed plastic bottles, prepares to embark on a transpacific voyage from San Francisco to Australia. Rothschild, a decedent of the famous English banking family, will make the journey to bring attention to sites of ecological importance that are susceptible to issues caused by climate change.

Their journey will take them through the Great Pacific Garbage Patch, a massive area of marine litter estimated to be larger than Texas, located between California and Hawaii.

De Rothschild is photographed with the Plastiki during its construction on the San Francisco waterfront. De Rothschild guided the construction of the massive sailing vessel constructed of recycled plastic and waste and held together with cashew nut glue. In an interview with the New York Times, de Rothschild said: "We don’t have the ability to get out of the way [of storms], so what we need is to have enough confidence in the vessel to say, 'Right, a storm is coming through, we’ll put up a little storm jib and hunker down and let it go over.'"

Rothschild has declined to say how much the vessel has cost him, but has lined up corporate sponsorships for the voyage, including custom-designed Nike high-tops and solar and wind powered electronics from HP. The crew will liveblog the journey, and have been making Twitter updates since their departure on March 19. Robert Galbraith/Reuters

One objective of the voyage will be to investigate the Great Pacific Garbage Patch. Captain Charles Moore, the man credited for first discovering the waste over 10 years ago, shows plastic samples collected in the North Pacific Gyre. The Algalita Marine Research Foundation has been studying and educating the public about the effects of oceanic micro-plastic pollution on the ocean's ecosystem and marine life for over ten years.

The voyage of the Plastiki will also investigate coral bleaching, an indicator of trouble with the symbiotic relationships in coral reefs. This undated file photo released by the Great Barrier Reef Marine Park Authority shows a bleached section of Australia's Great Barrier Reef, which scientists have warned could be killed by global warming within decades. A report on September 2, 2009 warned that Australia's Great Barrier Reef is in serious jeopardy as global warming and chemical runoff threaten to kill marine species and cause serious outbreaks of disease.
