Population planning and family planning and food (12/03/22 09:13:30)
At one level of population Earth will be on a point of no return - from loss of biodiversity, sea level rise, food scarcity from lack of fertiliser and loss of arable land to deserts, roads and buildings, and reactionary undereducation which cripples the mind and sabotages constructive developments.
So - how much recycled or sustainably acquired fertilizer minerals can we produce? So far it is only manure, which was insufficient even 150 years ago.
So better get started - either with phosphate and potassium recovery - or with worldwide contraception efforts. Ideally both.
