So today there is now officially over 8 billion people alive on our little blue planet

That's like making on income of 40 thosand a year but spending 60k every year. How long do you think that would last before your bankrupt? 

That's what we are doing with the Earth.

No it’s not, you’re using an average to make your point, and ignoring the fact that everyone isn’t using an equal amount of resources - some people consume more resources, other people consume less. You’d hardly argue that people who are wealthy consume equal resources as those people who live in poverty?

That’s why your analogy doesn’t hold - people on incomes much less than €40k consume far less resources than people on €40k, and the people on €40k have access to a far greater amount of resources than the people who are on much less than €40k.

How sustainable is it? It’s the very basis of the economic prosperity - people don’t generally care whether or not it’s sustainable so long as they continue to benefit from it, it’s not as though they have to live in countries where the population has increased significantly in the last couple of decades and Governments have taken no steps to harness the potential economic benefits of their greatest resources, that being their young population, by investing in areas like education and healthcare -

That’s where the whole argument of the idea that the “single greatest impact anyone can make in terms of global environmental sustainability is having one less child”, tends to fall apart, because while all children are at least created equal, they aren’t all born into equal circumstances, and they don’t all consume equal resources or contribute to economic instability or sustainability, in the same manner.

Nope. The world is able to sustain many, many times more humans.

The problem is not the number of us, it's the lack of us.

The disaster starts the moment the global population starts declining.

Every year less and less women of reproductive age, less young people, less innovation, less production and it's precipitous and year after year it will be exponentially faster and faster decline.

It's the end of human civilization and it can happen in the space of a single human lifespan.

I'm hardly the only person saying this. More and more scientists and policy makers are saying that we on the edge of a demographic collapse.

It's happening in China already.

Yet more anti immigrant ranting. It doesn't change how many are on the planet. Topics drift so quickly these days.....

And if human civilisation does end? Wouldn't be the end of the world, so to speak.

As poorer countries become richer their population declines and their drain on resources expands exponentially.

People on here wanting a huge world population want more people so their house prices can increase, so that there is someone to pay their pension, so that there are more people to do the **** jobs they think they are above doing.

They actually couldn't give a damn about the conditions people have to live in, or clean air, water, soil, free time, low stress , low noise environments.

They couldn't care about other life on earth.

Countries with tiny populations have created huge advancements. Everything we now have. AI can supplement this. Or maybe even take over. 🤣

And if guys are worried about women not wanting to be baby farms ... who knows maybe a scientific breakthrough will allow guys to have babies. 🤣

Edit

Just getting **** off my chest.

Don't hate me 🤪😂😜

"The world is actually under-populated with humans", is quite the take.

I think we need more humans to invent more ways of exploiting each other and the planet.

We've been building pyramid schemes since ... well since the pyramids 😂😂😂

This is exponential growth. If every 2 humans have 3 kids then the population goes up 1.5X in 15-25 years.

What you fail to mention, op, is that the worlds population is to peak in the 2080’s at 10 billion and then plateau.

We now have the lowest growth rate since the 1950’s.

If resources and wealth were more equally shared across the population what would that do to the birth rates?

It seems as though as countries get richer they stop producing children in such high numbers.

Is the increase in wealth a correlation or causation for the lowering birth rates.

IMO lowering birth rates in economically advanced countries is multi faced, but I do not believe more equitably distributing the planets wealth and resources would on its own negatively affect birth rates further.
