| What makes you think we're supporting more than is sustainable? Though I don't think we desperately need to make more people, as some people think we do, I also don't think we need to restrict lifespan progression. When I look at sustainability of the planet I consider
1) significant portions of the population are obese, and these numbers continue to trend higher. This suggests that we have an abundance of calories available to support more people. We have too much food. 2) water, and particularly fresh water is probably the most restrictive element we require. But I don't think we are restricted by a lack of water, we are restricted by a lack of clean water in the right geographic regions, and of course, the damage that we have caused to the supply. However, we are generating methods of creating fresh water. 3) energy may be the last resource, and particularly that major portions of our current energy needs are provided by damaging and non-sustainable methods. This doesn't mean we need to pause longevity potential, we need to find clean methods of producing energy, which is, and has been in development for a long time. Is there something else big that I'm missing here? |
