Ultimately nature will solve the problem itself, if we do nothing about climate change, nature will sort it and many of us won't survive, if we do not stop guzzling antibiotics nature will evolve stronger diseases and many of us will not survive it in tact, if we insist in not vaccinating a whole generation will die of avoidable illness, if we don't stop following religion's stupid rules we will kill each other.
Ultimately the cumulative effect will be a massive rebalancing of resources and vastly reduced population numbers.
Action needed to be taken a century ago, then we did not understand the necessity, fifty years ago we did but were unwilling to believe it ans twenty years ago it was all ready too late but was considered a threat to capitalism.
It is still not too late to mitigate the inevitable, but the sacrifices will be hard and unpleasant and a lot of people will die, but millions can be saved if we act, but we won't if it means giving up the three cars, the right to be obese and the HD TV because those are what makes life worth living

You can not make another person believe anything. Each person has to ponder the available evidence and form their own conclusions, and it is perfectly legitimate to have no opinion—you can be undecided or disinterested.

We seem so much hard wired to survive and reproduce that I doubt you’ll ever get enough people to forego having children to make enough difference. There are natural mechanisms for keeping populations in check: disease, war, predators, starvation, etc. that will do the job at some point. I would think that evolution works best under harsh conditions. A population of fat old people living in mansions is not going anywhere, in evolutionary terms.

A group of people might achieve a stable or declining population level only to be invaded by younger, more energetic and prolific immigrants.

If a person wants something to worry about, there’s no end of available topics. I prefer to concentrate on what is before me and to live in tranquility and joy. I’ll leave the worrying to y’all.

To quote Neil Young “Needle And The Damage Done”

To make a difference we seriously, individually, in our own corner of the world, must make a positive difference to raise our own neighbourhoods.

Rhetorical platitudes and ‘head up arse self-congratulation’ doesn’t cut it anymore. Bono et al. can fly around the world bleating ‘I Still Haven’t Found What I’m Looking For’ but in real life WE make the difference.

Particularly look out for the children. They didn’t ask to be here so it is our responsibility to say No More to the politics and policy making that retains all the risk factors they are exposed to like abuse, drug addiction and disregard for mental illness.

Forget Washington DC, London, Paris, Munich, New York (to quote M) and “make your Neighbourhood great again”.

I’ll now pass on the soapbox!

Past generations had as many children as they wanted... So why now, should the current generation be asked to give up their right to have a family.... Why should the current generation pay for the mistakes of the past...?
