Before modern medicine, advanced agricultural, and improved technology came along, the human population level was not as big a threat to other life forms as now. Indeed, human mortality rates and manifestations of the four horsemen kept our numbers much more in check. The average human life expectancy was much lower than now; but, we are now approaching a time when no amount of ingenuity nor scientific advancements will keep the former level of average human life expectancy from reasserting itself.
For the average individual, this means that the former level uncertainties of survival will resume as average global temperatures increase due to the increased blanketing effect that CO2 and other greenhouse gases have on infrared radiation. Nothing more, nothing less. Everything else is politics.
