Imagine if today, scientists showed you the Aurochs Wild Ox, and said — “Give us time. In just a few years, we will genetically modify this wild animal, turning it into a different sub species whose sole purpose is to provide vast quantities of milk for humans to drink. They will produce 10x as much milk as did the original animal. But they will require vast grasslands to sustain. And some of you will get sick because you won’t be able to digest the lactose. But no need to label this fact. People will just figure this out on their own. The rest of you will be fine. We’ll call the result a Holstein Milk Cow.”

What would anti GMO-laboratory people say this story? Would they embrace it or reject it? Of course, over the past 10,000 years, this is exactly what we’ve done to that Ox - or whatever is the agreed-upon origin of the domesticated Cow. Call it GMO-agriculture. If you reject GMOs you fundamentally reject it all.

“Incoming light from the sun hits the surface. The earth absorbs much of that energy, which heats the planet up and makes the surface glow in infrared light. But the carbon dioxide in the atmosphere absorbs most of that outgoing heat radiation, sending much of it right back to the surface. This makes the planet even warmer. That’s all there is to the greenhouse effect. It’s basic physics, just bookkeeping of the energy flow. There’s nothing controversial about it.”

For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You’d be surprised how far that gets you.

Favourite Moments from Cosmos: A SpaceTime Odyssey (1/?)

- From Episode 13: Unafraid of the Dark

Fun fact: This episode was directed by none other than Ann Druyan! I thought it was very fitting considering it was the final episode and it also talked about the Voyager program at great length.
