>We are very effective at breeding, especially with the help of science and technology.

In what sense? Our production rate is substantially lower than most other animals; mothers-to-be are made weaker than other animals during the process; the threat of death in childbirth for both child/mother is hardly the lowest of other animals

We have a relatively high population now, but its hard to imagine that its due to an efficient breeding process; rather our survival rate post-birth, lifespan and our phenomenal ability to edit the environment to increase resource production to support higher populations are likely better explanations

Put a pair of rabbits in a room and a pair of humans, with all needs met. We're not even competitive
