I drink protein shakes nonstop - three or four a day - and I run a lot, so you get rid of the bad carbs and keep the rest so you have the energy to make it through.
— Shia LaBeouf

In order for life to have appeared spontaneously on Earth, there first had to be hundreds of millions of protein molecules of the Ninth Configuration. But, given the size of the planet Earth, do you know how long it would take for just one of these protein molecules to appear by chance? Roughly 10 to the 243rd power, billions of years; and I find that far, far more fantastic than simply believing in a god.
William Peter Blatty protein quote

At the heart of the debate over intelligent design is this question: Can a scientific explanation of the history of life include the actions of an unseen higher being? The proponents of intelligent design, a school of thought that some have argued should be taught alongside evolution in the nation's schools, say that the complexity and diversity of life go beyond what evolution can explain.Biological marvels like the optical precision of an eye, the little spinning motors that propel bacteria and the cascade of proteins that cause blood to clot, they say, point to the hand of a higher being at work in the world.

The human mind treats a new idea the way the body treats a strange protein; it rejects it.
— Sir Peter Medawar

A billion people depend on fish for their main source for animal protein. At the rate at which we are losing fish, it is a human problem of enormous dimensions, a health problem of a kind we haven't seen before.
