Guys, imagine this.
The early models were used to project population, fossil consumption etc. etc. into the future based on technology understood at the time. But remember, initially due to acid rain and killer smogs in Europe, coal started to get shut down. Cars became more efficient, catalytic converters were invented to reduce emissions. Gas instead of brown coal, nuclear (many work very well), better and better systems to reduce electrical transmission loss.. it is endless and through all industry.
The predictions of doom caused a change in behavior, improvements in technology (many mandated, not just in Cali, American cars were basic until they acquired European and Japanese tech, some good work done though) and so the worst predictions have not occurred.
I know a parent who once went to town on another dad for "being a bully" to her kid about safety doing a dangerous enough sailing activity. It was sad but not a shock to head the boy was hit by a car in his bike when unsupervised (he lived). Identifying & nagging about clear and obvious danger is the job of the adults in society and it damn well works.
Be grateful you can breathe and yes, it will still happen (Venus Earth) without a lot more work.
