Birthrates are plummeting worldwide. Already half the world has "sub-replacement" birthrates. The dearth of babies coming means the makeup of human populations is about to change drastically, and that will affect everything. Radical population increase defined the 20th century; radical population decrease could well define our current century. This form of decrease---losing the young and keeping the old--- is something humanity has never experienced before.I'm waiting for someone to write the biography of Stewart Brand. What a resume!
