MARS TERRAFORMING





"After terraforming , Mars would once again lose its capacity to support life. But 100 million years is a long time. In fact, Earth might not be habitable for much longer than that. As the sun con- tinues to brighten, Earth will succumb to a runaway greenhouse effect. The oceans will evaporate, creating Venus- like conditions unsuitable for life. So our second planetary home might last al- most as long as our first. " Christopher P. McKay
