Trimix has made THE most pertinent point of the whole thread. Population!
If every person in the world had the same CO2 producing capability of Westerners such as the Americans, we would be in deep trouble.
We need to control numbers, but the population isn’t growing much in the developed world – we can’t afford kids easily.
The planet probably has more people than it can support already, but due to economic hardship in developing countries, these people don’t get enough food, let alone CO2 burning luxuries.
Children are viewed as pension providers in the developing world. Producing as many children as possible offers a better chance of secure retirement as there is such a high rate of attrition – poor healthcare, nutrition isses etc.
We do live in a sheltered corner of the world!
