The effect would be the same as everything else we've destroyed. 90% of the population wouldn't realize that they existed in the first place, 5% would acknowledge the loss to us all, & do nothing. 4% wish that there was a way they could help,& pass the buck. Leaving 1% that decide to help, but dealing with the bs & red tape reduces the #, until only a handful are left to do anything at all--we saved the buffalo/ bison & Eagle that represents our country, but every year the handful of folks helping dwindles, & will eventually stop. Our kids can read about gorillas.
