A new iPhone application called Locavore promises to be more in tune with the natural world than you are. Which, to be honest, shouldn't be hard for most.
Locavore uses GPS to determine your location, then feeds you information about what's currently in season in your area and what will be coming out of the ground in the near future. The developers expect people to utilize the app while perusing a local farmers' market to help them make decisions about what they should buy.
If you never find yourself with that dilemma, Locavore will also direct you to the nearest farmers' markets so you can then experience the problems their app solves. Convenient.
