Very true, Rita. I was reading on a butterfly site about how only 1 to 2% of eggs make it to adulthood. And they said as much as we want them all to survive, the consequences would be catastrophic. They used an example that started with 3 females and 3 males, and did the math to show that within 6 generations we would have literally trillions of that species of butterfly flying around if each egg reached adulthood! Imagine what that would do to the host plants! Nature is a pretty delicate balance but we have to trust that it knows what it's doing.
