If you live on planet Earth, you're probably scared about the future.

Terrorism, complicated international relations, global warming, killer viruses and a raft of other issues make it hard not to be.

Watching the news you have to wonder: is it safe to go out there or not?

In The Day It Finally Happens, Mike Pearl games out many of the 'could it really happen?' scenarios we've all speculated about, assigning a probability rating, and taking us through how it would unfold. He explores what would likely occur in dozens of possible scenarios - the final failure of antibiotics, the loss of the world's marine life, the abolition of the British monarchy, and even the arrival of aliens - and reports back from the future, providing a clear picture on how the world would look, feel, and even smell in each of these instances.

Hilarious, enlightening, and terrifying, this book makes science accessible and is a unique form of existential therapy, offering practical answers to some of our most worrisome questions.

Thankfully, the odds of humanity pulling through look pretty good.
