Some people believe that a life-support failure has already begun. They offer evidence that: + As of mid-2012, an estimated 15%, or 1/6, of the world’s population (more than one billion people) is malnourished or starving. Seventy percent of us (4.9 billion people) are unemployed or under-employed, have zero or next to zero access to healthcare and healthcare insurance, and are poorly nourished, clothed and housed. + Human activities are causing the extinction of an estimated 27,000 species of life each year. This corresponds to the rate of extinction around 65 million years ago when “the age of the dinosaurs” came to an end. There are a number of theories as to its cause, but a consensus of extinction event scientists is leaning toward it being caused by an asteroid as large as 10 kilometers (6.2 miles) in diameter that struck the Yucatan Peninsula in Mexico around the same time.
