A bunch of scientists have determined that:

"Despite population growth, logging and other environmental threats,
nearly half the land on Earth remains wilderness -- undeveloped and
nearly unpopulated, according to a study released today. The study by
200 international scientists, the most comprehensive analysis ever done
on Earth’s wild places and population trends, was seen by some experts
as a surprising cause for optimism. Biologists also viewed it as a warning,
since only 7 percent of the wilderness is protected." Let human beings attack their minds and hands to all this wilderness and we’ll make something of it! But, as the last sentence implies, it would not surprise me if there will now be a movement to protect what’s left; the "Forty-six percent club for no growth," or something like that.
