I've been storing the recylcing for a few days and its illuminating to see how much we can NOT throw out. Unfortunately here in Dallas, the wal-mart does not recycle plastic bottles -- only plastic bags. I'm hoping one of the upcoming venues recycles their plastics.
so I found out more about the 'great pacific trash heap' -- look at it like this, there's a "flattening" in the middle of a huge ocean due to earth's gravitational pull -- you can imagine this by the water simply being pulled into the earth.
It turns out that this is what creates circular currents in our oceans and like a giant 'whirpool' there is an effect of the trash collecting in the middle. Throw a plastic bottle off a pier and it may take years, but eventually it will circle its way into the center of these currents -- thats why there's an area twice the size of texas where you run past trash every minute... I'm sure with time it will keep concetrating.
