At global scale we can't solve the environmental crisis in general (climate is only one aspect) and solve poverty at the same time with 10 billion people.

Solving the environmental crisis means reducing our consumption of resources. Solving global poverty means a significant increase in consumption of resources.

So the only way forward is to let the global population decrease ASAP so that we can both live well and preserve the planet.

Resource intensity is decreasing. We can solve both at the same time, but we can’t solve both with maximum possible speed at the same time, true.

Resource intensity may or may not be decreasing but that's not solving the issue if you look at global numbers of poor people versus economic and consumption growth needed to bring everyone to, say, European level of living standard.

We are already wreacking havoc on the planet and marginal decrease in resource intensity is not going to make a difference because our total impact needs to be slashed.

I never understand the insistence of some of ignoring population in the equation, which is the key parameter.

> marginal decrease in resource intensity

We're seeing more than simply marginal decreases - if we can successfully transition our power. The gap in per capita CO2 emissions between developing, middle-income, developed is not nearly as great as what you are suggesting [0] and will decrease even further in the time that it takes to raise people in poverty now to developed-world standards.

> I never understand the insistence of some of ignoring population in the equation, which is the key parameter.

A few reasons: 1. Population is projected to peak in the coming decades. 2. "Slashing" population counts requires a global deployment of force that is both not practically feasible right now and incredibly unpopular. There is no practical path to "slashing" population. This is the primary reason, imo. 3. People in the West always imagine that it would be other people/nations slashing their population count when the biggest marginal impact (especially given climate lags) would be slashing their own population. These solutions are eugenicist in nature.

Also - taking a step back for a moment, I am confused as to how this in any way justifies beef. Beef contributes to the gap between rich and poor in CO2. If we reduce reliance on beef, it means we can support a larger population sustainably?

CO2 emissions for power generation, or in general, are only a small part of our impact. The environmental crisis is not only caused by this, but by our total consumption of resources and production of many pollutants.

And so we are screwed.

Now the West is already slashing its own population, birth rates have crashed. The issue is that it's refusing to let it go because it's not the easy option, and at global scale this is a taboo subject.

And so we are doubly screwed.
