I've always been fascinated by animal science. Specifically I think that a really good area to go into right now is entomology, or the study of insects.
Not just because they are so important to things like fruit crops and as disease vectors. Although if you're looking for careers in animal science, you could do worse than going into something to do with that.
But also because quite a few experts are predicting that insects will become a major food source in the next few decades.
Insects are a bit of a taboo food in most Western societies but in many other countries they are considered a delicacy, or even a staple.
They have high protein content and reproduce very rapidly. They convert energy much more efficiently than cattle. That means you can get more insect per kilo of grain than you can get chicken per kilo of grain.
People think of them as icky, but they used to think of caviar as icky as well. It was once a food that was fed to soldiers as a last resort when all other foods were gone, and now most people can't afford it.
I think one day insects will be just as sought after and it's worth getting into the study of them now.
