(11,683 posts)Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
Save the Earth as it is the best thing in much of the Galaxy.
But people have to get serious about the problem.
The Earth had a strict Occupancy limit of maybe 5 Billion people.
We're now 50% over limit and more than a billion of them are living in 19th Century conditions looking forward to getting into the 20th Century (not the 21st) and that's why India and China are building coal fired power plants weekly.
No amount of Teslas and Windmills are going to stop the crisis.
We need RADICAL changes like Bill Gates talks about in his new book.

People around the globe are having way fewer babies. By the year 2100, that might turn into a pretty big problem for humanity rather than the relief one might expect. If they arent already, dozens of countries populations will be going into decline in this century, according to a new study published in the Lancet this week. 23 countries are expected to feel this effect intensify, with their populations dropping to half of what they are now by the year 2100.
The global population will peak at 9.7 billion around 2064, according to the new projection, and then drop off to 8.8 billion towards the end of the century. Thats a pretty big thing; most of the world is transitioning into natural population decline, Christopher Murray, co-author and researcher at the University of Washington, Seattle, told the BBC. I think its incredibly hard to think this through and recognize how big a thing this is; its extraordinary, well have to reorganize societies.
The reality is that with more women receiving an education and entering the work force, combined with the wide availability of contraception, fertility rates are dropping, sometimes precipitously, around the world a stark reversal of the baby boom following the Second World War. Countries including Spain, Portugal, and Thailand will have their populations more than halve by the end of the century jaw-dropping, according to Murray.
But arent fewer humans better for a ravished world thats rapidly being drained of its resources? The researchers suggest that there may be fewer babies being born, but any positive consequences for the environment would be offset by the challenges of a rapidly aging population. Much older populations will create enormous social change, Murray told the BBC. Who pays tax in a massively aged world? Who pays for healthcare for the elderly? Who looks after the elderly? Will people still be able to retire from work? We need a soft landing, he added.

(43,349 posts)or most all of the rest of the giant population nations will be roughly the same or dramatically lower than they are now) in a country the size of Venezuela is MADNESS.
The US is tracking to be almost the exact same size it is now (331 million) in 2100 (336m)
Japan, Thailand, and Spain, were forecasted to have population declines greater than 50% from 2017 to 2100; China's population was forecasted to decline by 48·0% (?6·1 to 68·4).
