Because this is one of the root environmental problems we face. My grandmother was born into a world with 75% fewer people and this seemingly unstoppable growth undermines all of the good we do. If we halve consumption and double the world’s population, we have achieved nothing, but forced sterilisation is obviously completely unacceptable, as is the total freedom to have 9 children if you feel like it. You should care because at the moment the future does not look like now with more electric cars; you should more picture 40m people in rags foraging in a gravel car park the size South Australia for 27 potatotes.
I am adopted which is a life sentence of separation from my family and medical history and I find this situation very difficult as I age and face the fact I will never know the truth. Others should care about this because IVF technicians are making babies without recorded histories and we can expect they will fill the mental health system in the same way adoptees have due to unknown heritage and separation from mothers at birth.
I am asking because we are becoming more convergent at the same time we are becoming more divergent. We have the power to build and destroy each other and ourselves. I want to know what we are doing today to ensure humanity exists for future generations at the same time the earth is changing/evolving.
