After posting this on the "Breaking Items" proposal, I decided to add a few things and post it on its own.
I think that we need two types of water, shallow water and deep water. Not very many fish would be in the shallow water (I mean, how many fish would live in a stream where there are constantly people around?). The fish would be mainly in the deep water, like oceans or wide rivers. You could also wade through the shallow water, VERY SLOWLY.
Or the chance of catching a fish would be determined by how many people are near...
Another thing, I think we need a large open grassland to do farming on. Sure, there are small areas, but don't you think that real-life farmers would've cleared a spot to grow grain by this time?
