I took a class in college on Agriculture it was a fun experience learning about plants and animals etc. 
That's cool. Agriculture is the breeding and cultivation of animals, plants, and fungi for food. It is a heavily-researched field.
I suspect they make alot of money because with out the people who study Agriculture we would be lost.
That is correct. In fact agriculture was the key development for the rise in sedentary human civilization. Farming meant we didn't have to travel for food.
That is why I love and respect farmers a lot they give out the freshest foods and they are why we have low prices in food as well. 
Also the study of agriculture is referred to as agricultural science. It is a big area of study these days as more countries want to get into sustainable farming.
I just wouldn't trust alot of others countries in Agriculture they have all those chemicals and injections I will be very alert if they try and start selling to the US.
I understand your concern. Sustainable agriculture is when farmers use methods based on an understanding of ecosystems and relationships between organisms and the environment.
I dislike them doing that it can harm us and our family all because they want to make an extra buck.
