I don't think they will just follow our lead.
We definitely should continue research and strive to waste less. It's just some of the ideas aren't for everyone and environmentalists need to come to terms with this. Meat is a good example.
Population will solve itself. However so will carbon. It's the effects of the cycle I'm concerned about. Humans are fully responsible for human population. This isn't the case for ghg or carbon.
One thing I heavily support is nuclear technology. However it was the environmentalists who said no. Fossils kill many more people a year than nuclear. Deaths from fukushima are 0 (we are uncertain 9f canver but it is also much lower than cancer from fossils), but its all we hear about. Then we get people offering unrealistic solutions like solar and wind. If research into nuclear wasn't thwarted who knows where we would be at?
So, I agree that leaving Nuclear behind was a bit rushed and resulted in a higher usage of fossils, if that had been planned better the result would be much more sustainable too.
But I disagree that they will follow our lead, the entire world follows the lead what the European and northern american cultures dictate them. Starting with music, clothes, lifestyle, etc.
