They would sell anything they could to get money to survive.
No, it is not possible to survive in a black hole due to its extreme gravitational forces that would crush anything entering it.
Because people were so desperate they would do anything to survive.
They can survive just about anything but Raid and a shoe. They can stay under water 30 minutes, will eat anything including paper, clothing, crumbs. If a nuclear weapon went off they would probably survive that.
It is highly unlikely that anything directly at the site of a nuclear blast would survive due to the extreme heat, pressure, and radiation. However, some organisms like extremophiles have shown the capability to survive in extremely harsh conditions and may have a chance of surviving indirectly through protective mechanisms.
Without resources such as trees, minerals, water, etc. humans would not be able to create the things we have, survive, or do anything. Humans cannot survive solely on our own.
Not to my knowledge... Would be very surprised if anything other than certain bacterial and fungal spores survived.
The ants could survive generations because Carpenter ants can chew through almost anything. Carpenter ants will also eat almost anything, including other ants. It would all depend.
because if people need any help in anything about their body or how to survive, science would help them in those ocassions
A good job to have to survive an economic depression would be anything that was necessary. Medical positions are still needed, jobs in the food industry would be wise as well. Government jobs are usually protected and stay heavily staffed all the time.
No, it is not possible to survive being sucked into a black hole due to the extreme gravitational forces and intense tidal forces that would tear apart anything that gets too close.
No. Well actually we don't know. Considering the conditions on Mercury though, it would be virtually impossible for carbon based life to survive.
