My personal view? - no argument. I’m a closet scientist.
However I’m here as a devils advocate, and because I harbour some disquiet about the ease of genetic manipulation. We don’t yet know all the consequences.
One thing mankind is good at is acting today (in good faith) and desperately pushing back tomorrow. A simple example - the rabbit. Originally introduced to Australia and NZ as a food source these cutes animals have become a scourge. I’m sure there are similar examples in the US.
