Earth now holds 7 billion people. Some of us can recall when it was only 3 billion (1960). The human population on earth reached one billion in 1800. Estimates have us reaching 10 billion by the end of this century–a ten-fold increase in three centuries. Only 1 in 6 enjoy a high standard of living. At least 1 in 6 do not have adequate clean water. Many more are poor, hungry and sick. In Africa it appears that population control is more a consequence of disease, famine, accident, and war than family planning. Some religions teach that unearned suffering is redemptive and that’s fine if one believes it, but not if it’s deemed sufficient consolation for the poor, hungry, sick, and maimed. Too much life–human bodies occupying (not really sharing) the planet–is killing us. Denial of global warming seems to be a form of death-denial.
