Why "CAN"? Humans CANNOT live on planet Mercury. The temperatures on Mercury easily exceed 2000F or 1093C during the day.
Air conditioning
Humans prefer air temperature of 65-75 degrees Fahrenheit. The coldest place humans live is Vostok, Antarctica. The hottest place humans live is Death Valley, California.
They live in hot temperatures.
The one where the temperatures are least awesomely different from Earth is Mars. But that doesn't mean that it's actually anywhere close. Humans still couldn't live there in shirt sleeves with oxygen.
Since outer space has a temperature of about 3 K (-273 °C), the planets cannot be any colder, so if you can live there (the ISS) you can live anywhere. But as far as survivable temperatures for humans, only Earth qualifies. The next closest is Mars, which would need less heat to make habitable. The polar zones of Mercury have bearable surface temperatures as well, but they exist in a hard vacuum (as with space).
No, because Mercury is to hot, the day temperatures can reach over 430 C, and the night temperatures can go under 180 C. Not just that, but Mars is more convenient and nearer; humans would go and live there instead. It is 80,000 km away from Earth, and getting humans to the Moon was hard, let alone getting to Mercury. Another thing is that we don't know enough about Mercury to live there. There are really endless anwers to this question, so feel free to add or change this answer slightly.
Zebras live in hot climates and temperatures where they can dip in the cool water or drink it.
they live in solitery confinement
Humans can't fly or breath underwater, without mechanical assistance. Humans can't go more than 7 days without food or water in normal temperatures. Humans can't survive in extended exposure to temperatures below -40C or above 60C.
they live in cold water.
depends where you live because you might have higher temperatures where you live where as i might have lower temperatures than laos or poland
