Is There a Solution to the "Continent of Plastic" that Pollutes the Pacific?


The UN Environment Program estimates that there are 46,000 pieces of plastic litter in every square mile of ocean, and a swirling vortex of trash twice the size of Texas has spawned in the North Pacific.

Plastic bags, once icons of customer convenience, cost more than 1.6 billion barrels of oil per year and leave the environment to foot the bill. Each year the world produces 500 billion bags, and they take up to 1,000 years to decompose. They take up space in landfills, litter our streets and parks, pollute the oceans and kill the wildlife that eat them.

Eco-friendly legislation that targets the production and distribution of plastic bags has been introduced in Israel, San Francisco, Ireland and China. Addiionally, a recent scientific discovery (see below) offers a potential long-term solution to the global plastic crisis.

Since stories have started surfacing more recently, many have wondered, if the rumors are true. Are there really 'continents', or massive floating garbage patches residing in the Pacific? Apparently, the rumors are true, and these unsightly patches are reportedly killing marine life and releasing poisons that enter the human food chain, as well. However, before you start imagining a plastic version of Maui, keep in mind that these plastic patches certainly aren't solid surfaced islands that you could build a house on! Ocean currents have collected massive amounts of garbage into a sort of plastic "soup" where countless bits of discarded plastic float intertwined just beneath the surface. Indeed, the human race has really made its mark. The enormous Texas-sized plastic patch is estimated to weigh over 3 million tons.

Sadly, marine researcher Charles Moore at the Algalita Marina Research Foundation in Long Beach says there’s no practical fix for the problem. He has been studying the massive patch for the past 10 years, and said the debris is to the point where it would be nearly impossible to extract.

"Any attempt to remove that much plastic from the oceans - it boggles the mind," Moore said from Hawaii, where his crew is docked. "There's just too much, and the ocean is just too big."

"When oil prices soared in 2005, that changed a lot of people's perspective, because bioplastic became quite cost-competitive," she says. "All of a sudden it wasn't just about doing the right thing."
