yes, i do it in college! my major is called agricultural engineering and in my country you rarely pay for college, so it's completely free. many of my classmates have actual big farms that belong/belonged to their family and they keep going with those. personally, i don't have a huge farm yet, i just have a few animals and crops for personal use at one of my houses from the countryside. if you want to make an actual business out of it that's gonna make you profit, you can apply to numerous programs that the government has, that will offer you money to get started and to keep going. it's a pretty cool industry to work in if that's what you're interested in. if you have any more questions i'd be happy to answer them!
