Survival of our species/Risks to humanity
From AdCiv
- Strike by asteroid or comet
- Genetically engineered biological weapon or lab-experiment let loose (accidentally or maliciously)
- Out of control self-replicating molecular nanotechnology
- Nuclear weapons
- Increasingly powerful particle accelerators. Some physicist think we have already created phenomena similar to black holes [1], although theorists believe these pose no risk as they evaporate extremely quickly. Although the very reason people are doing these experiments is because we do not precisely know how nature behaves at these extremely high energies.
- Climate change. It is more likely to affect other species that do not have the means to adapt first. But if it gets to the point where it affects species we rely on for our own survival then we will be at risk.
