Smurf I don't know what you mean by this.And so I have a mix of male and female mice with no breeding over the past few months since the resource constraints became apparent. Prior to that, population was booming.
Now, if a few mice can work this stuff out then you'd think humans would "get it" too? Apparently not...
It is well known that in the US, Europe, Australia and Japan (and probably more places), the birth rates have been dropped to below replacement for quite some time.
Indeed, last I heard, Japan and some european countries had birth rates around half the replacement level. (Replacement level is considered to be about 2.1 births per woman).
In humans, it is indeed hedonism which fulfills the function of reducing births in advanced societies. Raising kids takes effort, it requires committing to one partner, it requires diverting money from your frivolous luxuries towards raising the kids, you can't spend every weekend getting smashed and chasing a lay etc. Lots just don't bother.
However, herein lies the rub - politicians, instead of accepting demographics, decide they disagree with the demographics. They have ideological slants towards immigration, since it 'creates diversity (changes the nation into something else)', 'supplies much needed labor in X', 'offers a better life for those who live in bad places' etc.
And then there are the capitalists who desire the immigration, since it depresses the wage rate decreases input costs, and raises profits. Hence, they are always keen to lobby for increased immigration.
And thus we end up with the current farcical situation, in which 'our' population instead rises at twice the world average - even though the fundamentals would otherwise cause it to decline.
The issue is that the price for doing this is actually enormous. Hence the 'only' downside is also enormous.I'd like put forward a different angle.
If global warming is not man made, and we go to all the trouble of making everything 'green', then at worst we will have created clean air for our cities, lots of new jobs and technologies. We have also reduced our dependence on arab states for greatly diminishing oil supplies. The only downside is cost.
So even if it's just natural cycles occurring, it's still of great benefit to make everything low carbon emission.
If on the other hand the warming is man made, then we've covered our risk side of the equation.
Could I just point out that humans existing is good? 'Pollution' is a necessary byproduct of our existence. And I fail to see how nuclear is a flawed solution. (Unfortunately I posted a response about nuclear the other day and it doesn't seem to have gone through )ALL power pollutes. ALL of it. All we get to chose is what we wreck, where, and in what manner. But if the lights are on then there's an effect on the natural environment somewhere. Even solar comes at a cost to the environment larger than most realize.
All that said, agreed that we ultimately do need to stop burning fossil fuels. What I'm worried about is that we adopt flawed "solutions" (eg nuclear fission) due to a perception that the change is urgent when waiting longer would give rise to far better alternatives. The perception that it is urgent really leaves us with no choice other than to dam the lot and nuke the rest - not what I'd call "green" by any means.
