Mars is a hostile planet, and is currently unable to support human life. Stephen Hawking has said our time on Earth is running out and we must start searching for new planets to live on if we are to survive as a species. Hell, we can't even go everywhere on Earth.Try climbing a large mountain without an oxygen supply. To survive on Mars, humans need the same things they need on Earth: water, a breathable atmosphere, and food. For humans to survive we need oxygen, therefore any planet which does not have oxygen would be unsuitable for us to live on. If we can't survive on our own planet and learn to live with nature, then we will never find a way to continue anywhere else. None of us would be alive today without plants, and if humans want to survive beyond Earth long-term, we’ll need to bring our leafy greens with us. Humans need to colonize another planet within 100 years or face the threat of extinction, high-profile physicist Stephen Hawking has warned. Take energy production: In order for humans to live on another planet, we will need to develop a way to produce electricity. We need water for many reasons such as to grow food or for other animals. NASA and other agencies have been trying to figure out how to put humans on Mars for many years. If we ever become—perhaps if we need to become—a multi-planet species, exactly how many settlers would be needed for survival on another planet? References "Journey to Mars." "With 10,000," Smith says, "you can set off with good amount of human genetic diversity, survive even a bad disease sweep, and arrive in numbers, perhaps, and diversity sufficient to make a … The answer, according to … We sure have and that's why we decided to find out what it might be like to live on other worlds in our solar system, from Mercury to Pluto and beyond in a new, weekly 12-part series. For reference, the U.S. Dept. We also need a supply of water. So, beyond the very unlikely event that your alien planet has a size and atmosphere practically identical to Earth, you're going to spend your whole holiday in a … of Labor's OSHA defines 19.5 percent oxygen content as the minimum safe concentration for humans. One thing is for sure—we need to get our own house in order first. But before humans venture to distant worlds, they'll most likely be starting with a colony on the moon. The late physicist Stephen Hawking believed that humanity needs to colonize another planet within the next century, if it is to avoid the threat of extinction [source: Kharpal].
