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.
Humans are great at adapting to their environments.  No wonder we've come so far.  Do you think there are still things that are yet to be learned when it comes to agriculture?
Selective breeding and modern practices have increased our output of meat but raise concerns of animal welfare. There is also concern about global warming and leftover waste products.
That is precisely why I promote the "No beef" attitude when it comes to hip hop.  Nobody wants to own up to how the modern practices have led to a decline in quality.
