Yes I agree, the best way to save the planet is to reduce the population.
In this country a very unpopular way would be to tax people for having say more than 2 children (1 would be better) and to stop child allowances, which encourages people to have more children as they are cushioned from the real cost of bringing up offspring.
I cannot see any government biting the bullet and stopping child allowances but it would release a lot of cash which could reduce taxes and the savings could be redirected to other public needs.
To be fair in modern western countries populations are stabilising and birth-rates dropping. Of course, the population numbers take time to reflect this as people live longer. And China deserve more credit than they are given for biting that bullet.
Obviously with religion in decline it is less of a factor in countries that offer freedom of choice.
But I'd want a 2 billion max. I think that would be sustainable and leave room for even large mammals, and thus their environments, to survive.
But maybe destroying the planet is inevitable. It certainly is another of many theories which explain the Fermi paradox
ps. The rum followed by Cider Christmas puddings, accompanied with custard and cream, were well received by the Spanish. Of course I had to explain that next year I would be charging an extra tariff
