Technology, although nice, is not the answer. Just because we can play God and produce designer foods, "fake" meat in factories, and unusually fast-growing fish, should we? This is a question that each of us needs to answer before it is too late.
Since the plants don't need dirt, aquaponics allows gardeners to produce more food in less space. And in addition to the vegetables they can grow, most aquaponics gardeners cultivate edible fish as well.
Is there a way of producing fish that comes as a byproduct of restoring ecosystems, of regenerative practices that require not 10 to 20 pounds of small wild fish (ground into fish pellets) to produce one pound of the fleshy fish we humans so love to consume?
85 percent of oyster reefs have been lost globally. In many bays, once-plentiful oyster reefs are now functionally extinct. But shellfish lovers shouldn't panic -- most of the oysters they eat today are farmed.
The shrimping industry itself is an environmental scourge much older than the oil spill. Farming is responsible for habitat destruction, while trawling for wild shrimp is harmful to the oceanic environment. So which is the lesser of the two evils?
Ever hear of a "dead zone"? I don't mean the book by Stephen King. I'm referring a typically large swath of ocean that is so depleted of oxygen that most aquatic life caught in one either suffocate or escape the region.
