Good morning. πππ
21 October 2024
What happens when a species has no natural predators? I've read a little, not a lot, about such events such as the introduction of rabbits in Australia, the rabbits became a big problem, though I don't know if they still are. They gobble up all of the resources, don't they? Is Homo Sapien so different? No natural predators, except for ourselves. Populations grow virtually unchecked. We're at what, eight billion? That is a growth of about two billion the last twenty years. The more of us there are, the more resources we require. How many of us can the earth sustain?
Hmmm ... it must be doom and gloom morning.

Cats kill billions of native animals annually, and are responsible for the extinction of at least 22 native species in Australia.

Wow, I didn't know about that. Cats are a problem in the USA as well but apparently not as big of a problem.

Most of the cats doing that are feral cats. They are highly adaptable and are common even in remote, arid areas. This is not to say that domestic cats arenβt a problem, & Iβm all for sterilisation & keeping them indoors. But domestic cats are only a small part of the problem.
@Susan60 @stib @FerdiMagellan
Yes, sterilization would help with domestic cats. I don't suppose feral cats help keep rabbit populations in check.

They probably do, but they also wipe out populations of small marsupials like bilbies. Most Australians arenβt familiar with these animals. Theyβre often nocturnal & very shy. We know about & love our kangaroos, koalas etc (even as we allow habitat destruction to result in koalas becoming endangered), but we give little thought to the smaller nocturnal marsupials.
