Throughout history, solutions have led to more solutions. The invention of the wheel gave rise to the cart, the paddleboat, and hydropower. Mendelian genetics led to DNA forensics. But progress stalls as it nears its goal of the good life. The internal combustion engine produced the automobile, but the automobile produced global warming. Special Relativity made nuclear fission possible, which made Hiroshima possible. Because our grandfathers discovered how to amplify crop yields with pesticides, we must discover how to unpoison rivers and nurse dying species. Scientists seek cures for cancer, AIDS, Alzheimer's, diabetes, and multiple sclerosis, but if they succeed, our grandchildren will seek cures for overpopulation. In the beginning, humanity solves the problems nature made; in the end, the problems our own ingenuity made.
