(9/18/2012) A college degree is the key to realizing the American dream, well worth the financial sacrifice -- at least, that's what we've always believed. But the cost of going to college has never been so high and the value of that diploma has never been more in doubt. We profile several entrepreneurs who are trying to make college education more affordable, accessible…and relevant to today's job market. Also, what started out as the innocent practice of releasing an unwanted house pet into the wild is now threatening to destroy the already fragile ecosystem of one of the nation’s most majestic national parks, Everglades National Park. The Burmese Python has grown into an infestation that numbers an estimated 100,000 -- and in some cases, these pythons are depleting the park of indigenous species to the tune of 90% or more.
