It's no secret that uncurbed climate change and population growth are going to (and already have) put stress on the planet. But the situation is getting so bad that one prominent NASA scientist says we have to start thinking about terraforming Mars and that, in order for the human race to survive at current levels, we will eventually "need at least three planets. The entire ecosystem is crashing," Dennis Bushnell, chief scientist of NASA's Langley Research Center said Thursday. "Essentially, there's too many of us. We've been far too successful as the human animal. People allege we're short 40-50 percent of a planet now. As the Asians and their billions come up to our living systems, we're going to need three more planets."IOW, NASA is paying for idiotic Malthusianic nonsense, instead of space exploration. OTOH, Elon Musk is using the same "Earth is running out" alibi to build his Mars colonization project. Extra to X-Planets and APoD.
I vote we send this guy and his colleagues on a one way trip to Mars as the advance party. After all, life here is getting intolerable, right?
