The biggest threat to the human race is the rise of the global environment's temperature. The reason for that rise in the temperature is that we use energy sources that are delivering carbon dioxide to the atmosphere causing a rise in the temperature. We use old-fashion technology because we don't want to invest the new energy sources.
Technology and especially, wrong-used technology can cause global problems. Things like carbon monoxide emissions, waste of natural resources, and pollution along with overpopulation are causing very big risks. So those risks are more problematic than some military technology because people think that civilian technology is safe. Things like pandemics can cause very large-scale human problems for mankind.
Even if epidemics will not kill people directly things like epidemics that are destroying food such as corn and rice can cause famines. Also when we are thinking about polluted ground and water, those things can cause very bad situations. But the biggest threat to us is the carbon emissions that are overheating our planet. The problem with those kinds of time bombs is that they are not weapons.
Humans are used fossil fuels long time. That means the entire energy environment is made to use oil and natural gas. There are many nations in which economics are basing the sale of oil and gas. Cheap oil and gas are denying the use of green energy. And the reason for that is that the new energy sources require investments.
But another reason for slow investments in renewing and carbon neutral energy sources is that nations like Russia are getting the main part of their foreign incomes from gas and oil. If other nations turn to using other energy sources the money that those nations are paying for gas and oil is turning into another pocket. And that means that the incomes of those oil and gas exporting countries are decreasing.
