Test should be required to own dogs and cats and people shouldn’t be able to own more than three pets max. The same way you need to pass a drivers test in order to operate vehicles and more advanced drivers test for more advanced and complicated vehicle, that needs to apply to pet ownership as well.
Most people can’t handle owning pets, they are incapable or don’t have the resources to do so. This isn’t even including the neglectful and abusive pet owners who don’t maintain the hygiene of the pet or property the pet is in.

Growth is good, more people is more opportunity. There is an equation where growth is good and it gets to a point where the negative effects of growth start to outweigh the positives. Most countries are nowhere near reaching that point and the negatives are mostly just cost to build more infrastructure which is quickly resolved by having a larger tax base.
I’ll use New Zealand as an example. At 5million I think its good we grow. At 150million its probably time to talk about incentivising less growth. At 1 billion we need to be making policy to reduce growth urgently.
