Rising Temperatures Are Bringing Back Old Viruses

Bill Gates might be right in his predictions that in the next 15 years, 33 million people could be wiped out in less than a year by a pathogen. You see, the rising temperatures due to our climate change crisis are bringing back old viruses that our immune system have no idea on how to combat (watch the film below).
He says it also could be due to mutation, accident, or terrorist intent. Similar events have occurred before: the most obvious example is the Black Death, which killed almost a third of Europe, but more recently, in 1918, the Spanish Flu wiped out between 50 and 100 million people.
I really really hope we get magic powers with the CRISPR technology before something like this breaks out so that we have ways to overcome those viruses.

Creepy right?
