Epidemic or Crisis?

In this article, parents are now going to receive letters if their children are obese in the UK. Okay, great. That's a start. But at the bottom of the article we see that "Two thirds of adults and a third of children are either overweight or obese in the UK. The figure is predicted to rise to almost nine in 10 adults and two-thirds of children by 2050, which could cost the economy £50bn due to obesity-related ill-health."

Apparently they don't predict that the strategy will do any good. This is more than alarming. If this trend in the UK holds true world wide, I'm not sure the earth can sustain it, especially given that we may be trying to house over 10 billion people by then.

Is this an epidemic or crisis?
