One of the big questions people have in the agriculture space is: with limited arable land and water, how do we resolve the growing demand for food? We need more crops! The answer is in technology, and seeds are a big part of that. The other part, but often overlooked, is actually in machinery. The John Deeres of this world, for example, have allowed farmers to be much more precise, much more efficient, and, I think, that has created big advantages in terms of yield. For example, with spacing down, i.e., seeds planted closer together, you also get bigger yields.
