One way is how we obtain our food.Everyone has to eat, right? Where did our food come from? How was it grown (cattle and fish farms), farmed, caught, or even gotten from a processing plant? What is the trail our food has come from..i.e. where was the rice grown for sushi? where did the fish come from? where did the caviar come from? what fish and where? seeweed, where in the world did that come from? Our food and where it came from is a story of its own.
Another way how our everyday lives intersect with biology is how our body changes. Whether you are getting older- your body changes. Every living being changes as they get older.
