Zitat des Tages von Nina Fedoroff:
If there are more and more environmental refugees, they are going to end up on your doorstep too.
One of the really remarkably beneficial aspects of genetic engineering is that much of the previous methodology for controlling pests and so forth is through chemicals that affect a very broad spectrum of insects, for example, or fungicides that control fungi.
In the last century, as we learned more about genes, we were able to devise ways of accelerating evolution.
Civilization depends on our expanding ability to produce food efficiently, which has markedly accelerated thanks to science and technology.
We need to continue to decrease the growth rate of the global population; the planet can't support many more people.
Jumping genes are fundamental because they're agents of change. Everybody knows that organisms evolve. What makes them evolve is that their genes are dynamic and in motion. A familiar example is the stripe-y corn - called Indian corn - that you buy in the fall.
Weeds do become resistant to herbicides, and it needs to be managed with multiple herbicides.
Even as the population doubled from three to six billion, we managed to race ahead with all kinds of technological and scientific events in agriculture - from using more fertilizers to mechanization to advanced plant breeding.
We wouldn't think of going to our doctor and saying 'Treat me the way doctors treated people in the 19th Century,' and yet that's what we're demanding in food production.
There are probably already too many people on the planet.
We are sliding back into a dark era, and there seems little we can do about it. I am profoundly depressed at just how difficult it has become merely to get a realistic conversation started on issues such as climate change or genetically modified organisms.
In agriculture, people have taken wild plants that can't be eaten by people - and turned them into wonderful food sources. And that's because genomes can change, and people working with plants have picked mutations. Mutations are nothing more than genetic changes.
We've gotten so good at growing food that we've gone, in a few generations, from nearly half of Americans living on farms to 2 percent. We no longer think about how the wonderful things in the grocery store got there, and we'd like to go back to what we think is a more natural way.
The more we can grow on already cultivated land, the better.
In many places in the developed world, we eat or waste probably twice as many food calories as we really need. We're wasteful of food. We ship all over the world. We're now realizing that generating the energy to ship the food around the world is also ruining our climate.
