Agriculture is cultivating and breeding of animals and plants. This provides us with food and medicines. They help us to sustain life.
I find that interesting.  How do you know so much about agriculture?  Are you a farmer?
Oh no way! lol I'm no farmer. Agriculture was the key in the rise of sedentary human civilization where farming of domesticated species provided food that nurtured the development of civilization.
It's crazy to think how far along that we've come as a civilization.  What are some of the animals that are bred most in order to provide us with a consistent food source?
I would imagine poultry and pork. The history dates back thousands of years and is defined by different climates, cultures and technologies.
