Boris johnson on over population in
2007:
[extract]
Depending on how fast you read, the population of the planet is growing with every word that skitters beneath your eyeball. There are more than 211,000 people being added every day, and a population the size of Germany every year.
As someone who has now been travelling around the world for decades, I see this change, and I feel it. You can smell it in the traffic jams of the Middle East. You can see it as you fly over Africa at night, and you see mile after mile of fires burning red in the dark, as the scrub is removed to make way for human beings.
You can see it in the satellite pictures of nocturnal Europe, with the whole place lit up like a fairground. You can see it in the crazy dentition of the Shanghai skyline, where new skyscrapers are going up round the clock.
You can see it as you fly over Mexico City, a vast checkerboard of smog-bound, low-rise dwellings stretching from one horizon to the other; and when you look down on what we are doing to the planet, you have a horrifying vision of habitations multiplying and replicating like bacilli in a Petri dish.
The world’s population is now 6.7 billion, roughly double what it was when I was born. 
If I live to be in my mid-eighties, then it will have trebled in my lifetime.
The UN last year revised its forecasts upwards, predicting that there will be 9.2 billion people by 2050, and I simply cannot understand why no one discusses this impending calamity, and why no world statesmen have the guts to treat the issue with the seriousness it deserves.
How the hell can we witter on about tackling global warming, and reducing consumption, when we are continuing to add so relentlessly to the number of consumers?
The answer is politics, and political cowardice.
It is time we had a grown-up discussion about the optimum quantity of human beings in this country and on this planet.
All the evidence shows that we can help reduce population growth, and world poverty, by promoting literacy and female emancipation and access to birth control. Isn’t it time politicians stopped being so timid, and started talking about the real number one issue?

Some deadly viruses introduced would also affect the world population, not just by deaths but the social distancing and lockdowns, maybe this is the beginning of more than a one-off virus?
You can bet your bottom dollar if somebody like boris is thinking these things and breaking cover in 2007 the debate is far more advanced by now among the upper echelons and govts...'what to do about this massive growing population?'
I can't argue with his main point in that article and description of the situation, but a slight double standard as he's fathered at least six children himself
