g7,
Gene mixing isn't new.
It's been taking place on Earth for as long as there's been sexual reproduction.

In addition, plants seem to do this spontaneously.
It's true that genes from (for example) fish, and plants probably haven't mixed much.
But such genetic engineering has produced for us temperature hearty tomatoes, rice with a nutrition profile good enough to prevent diseases in the 3rd world, etc.

Historically, I suspect humans have done more by re-engineering the alphabet, meaning putting letters and words in sequences never before having been seen; than they have re-engineering genes.

But I acknowledge the danger. Like the man that leaps out the 100th floor window, being heard to say as he plummets past the open window on floor number eight: "No problem so far!"
