For all the ballyhoo about genetically modified organisms (food, in particular) making the world a better place, there's also the fact that GMO technology is big money.

Bt toxin could harm aquatic ecosystems.

Let's assume imagine that there are good ways to handle all the worries about GM-crops in the world that I raised in my last post -- that there won't be collateral damage among the non-targeted species, that the targeted species won't become resistant, that the GM crops will be sufficiently isolated from non-GMO crops that their genes won't end up in the larger agricultural gene pool counted upon by seed savers and other non-corporate-licensee farmers. Let's further assume that the GM crops are nutritionally sound with no unforeseen consequences (e.g., allergic reactions) to those consuming them. Will the consumers want...

The technology for creating genetically modified organisms (GMOs) is appealingly clever, and it opens up a host of possibilities for engineering crops and livestock to order. But how things work in theory (and in the lab) does not necessarily tell us all we need or want to know about how things will work in the world. Consider transgenic Bt corn, corn genetically modified to express the Bacillus thuringiensis toxin, which is poisonous to many insects. The appeal of Bt corn is that it makes its own pesticide, poisoning the voracious insects that might try to eat it without the need...

The potential of genetically engineered organisms—particularly in the areas of medicine, biotechnology and agriculture—is seemingly limitless. Is your soil too acidic for your eucalyptus trees? No problem. Just introduce genes from carrots, which thrive in slightly acidic soil, to your trees—and voila, healthy eucalyptus! Cells can't produce growth hormone? Genetically engineered bacteria can do that for you. Need to know where a specific protein is directed to within a cell? Just tack on the gene for green fluorescent protein—taken from jellyfish—to the DNA of the cell in question, and you'll find the answer illuminated. Genetically engineered organisms may seem like...
