Some people are very concerned about the number of birds that are killed by cats, buildings and wind turbines.
But have they considered that birds have a high birth rate to offset their high mortality rates?
For every bird killed, that's one less bird that needs to starve to death.
Birds become endangered for other reasons.


Uh uh, and using that reasoning the sky ought to be blackened by flocks of passenger pigeons to this day, since you know, they have a high birth rate to off set high mortality rates.

Introduce an invasive specie (cats), or subject an ecosystem to anthropomorphic modifications (buildings, wind turbines...deforestation) and you're liable to displace or exterminate specie native to that ecosystem, even those whose best defence tactic is rapid reproduction.

Im sure you know this, but getting back to birds: they're not all like English sparrows and starlings in their reproductive capacity. By the way, both are invasive species that have displaced native ones to their detriment. Once again, inadvertent consequences due to anthropomorphic meddling.
