There are small/tiny farms making tremendous profits. These farms are producing products that others have not been able to figure out how to grow or even thought of growing. These products are not necessarily
food. These farms have developed strong niche markets with loyal customers who gladly pay premium prices because nobody else can reliably provide the product. These farms aren't near their customers; think UPS Next Day Air.
These farms don't have websites and avoid publicity. The last thing they want is competition (business against them).
There are plenty of wild animal and plant species waiting to reward ambition, skill, and hard work with a unique, interesting, sustainable, and lucrative farm business.
