Well, there was so much I learnt in class about pigs that I didn't know before. I mean aren't pigs just good for food?
I knew about the fat being used for bio-fuel from watching “The Colony”. I thought it was something they made up just for the movie, guess I was wrong. It’s pretty amazing though. In the movie an old man who was a farmer gave them the idea. The fat had to be boiled to just the right temperature until it became pure oil. They then poured it into an old van and drove off!
The thing about pigs being the fourth most intelligent animals in the world was a revelation for me. They don't seem to do anything but eat and lie in the mud all day. And then, there sense of smell is so highly developed that they can sniff and find things underground, and even help policemen find drugs? I thought that was a thing for dogs alone. Imagine going through the airport and having a pig check out your luggage! - written by Josiah
