The most obvious factor affecting Iowan food output, and thus that of the world, is the weather. If the weather is bad and reduces yields, food could be scarce in many parts of the world. Price fluxuations will also affect how much farmers plant and harvest and how much the world receives.
Mr. Leeds commented the most on keeping current with what’s going on in the world, saying that he subscribes to five newspapers and several other publications. He is also keeping up with the changes in technology by receiving a lot of these publications online through email subscription.
Our agriculture is shifting away from multiple small farms to fewer, larger farms. The location of farms is also undergoing change, as many farms are springing up in cities. Indoor farms are becoming more prevalent in major metropolises such as Chicago and New York in order to better sustain their large populations. Many companies are also planting gardens as office boding activities and as a way to become more economical.
I completely agree with the food output depending on the weather. I've definitely seen that firsthand where I work and all the rain we had really had an impact on corn and beans. However, the corn has really turned around so now we'll see if we can avoid an early frost like last year.
The issue of the weather you brought up is a really valid point. Even though we have such innovative technology, the process is still dependent on mother nature.
