recycling

Aquaculture is growing in popularity around the world, but the high density of waste created by fish farms poses an environmental threat. David Love, a project director at the Johns Hopkins Center for a Livable Future, is trying to solve this problem through aquaponics -- the recycling of fish waste to feed vegetables growing on rafts.

The United States is the most wasteful country in the world, accounting for only 5 percent of world's population yet creating 25 percent of its trash. Americans make 50 percent more garbage per person than other Western economies with similar standards of living, with each American on track to produce 102 tons of garbage in a lifetime. So how did we get here? And how do we solve our current trash crisis, and stop our addiction to disposable consumption?
