Hmm.
Well, humans have been genetically modifying plants since pre-history. It started with the very first time a human saved a few seeds from a crop that performed well.
Today, almost every plant you interact with as food or in your landscape at home is a product of such human intervention.
It is a double-edged sword and always has been. A given plant is selected for a certain trait or traits that are beneficial to us, unfortunately, other traits are removed from that plant's genome in the process. This has left the plant vulnerable to destruction by way of disease and susceptability to environmental conditions that the original wild stock could resist.
This sort of activity, along with global transfer of plant species, has both helped humanity and harmed it . We are the creators of this reality as well as its stewards, and we have made great strides as well as terrible errors.
Here are a few facts:
- The American Elm is now essentially extinct because humans brought a disease across the Atlantic along with European Elms.
- The same fate has befallen the American Chestnut.
- Honey bees are not a native species here, yet our food supply depends on them.
- The earthworms you see everywhere are also non-native. And though we consider them to be beneficial, they have fundamentally changed the continent's ecosystem.
Now, we are messing with nature via the laboratory through the use of chemical and genetic engineering - and thus raising the stakes even higher along with our responsibilities.
We will continue to make advances and mistakes, large and small. What appers to be one may morph into the other at any time.
Perhaps nowhere else in human endeavor does the peril of unintended consequences apply more completely.
If it looks like I haven't taken a side here, there is good reason for that. On this subject there is simply no room for entrenched positions - the goalposts move constantly.
