Yellowstone National Park is full of science and history and the web series 'Awesome Science' hosted by teenager Noah Justice came to Wyoming to check it out.
Wyoming's got 3 food groups. Red meat, potatoes, and booze. So when I came across this study that said we need to cut down on our red meat consumption I almost died of laughter. We will not be doing that despite what some study has to say.
Now, I'm not very educated when it comes to 'sciency' things that's why I rely on places on the internet to confirm that I made the right choice in my career choice. Sciencenew.com has an article saying the mammals used to be a lot smaller than they currently are today.
