We can not live with out trees
No, human beings cannot survive in space without proper protection such as a spacesuit. In the vacuum of space, there is no air to breathe, extreme temperature variations, and harmful radiation that make it impossible for humans to survive.
They basically do what humans do to survive. Like humans need to eat to survive and we also need to sleep to survive.
The first animals were launched into space to see if it would be possible for them to survive in space at all. Once that was settled and humans went into space, there was no longer a need for space pets.
To survive in outer space, a man needs to have oxygen, water, food, space suit, warm clothing. We would also need a gravitational force similar to earth's, otherwise we would suffer rapid muscle degeneration, and eventually death. This is why astronauts must constantly exercise in space.
Humans need to maintain enough space and resources to increase the earth's capacity for all species. They have to make sure that they and other people have enough to survive.
yes
Yes.
cause we do
to see if it was possible for humans to survive. if the dog couldn't survive it wouldn't be good for humans. it wouldn't guarantee humans couldn't go it but they would know what they where dealing with
Yes, and No. Cows can survive completely on grass as food, but it would need water too.
Only if they are in an enclosed capsule with a life-support system.
nothing really he just went up in a rocket to see if animals could survive in space then if they could then they could test humans.
