Tech tools to eat sustainable

Two interesting iPhone applications :

Locavore

Eating local food when it’s in season is an increasingly popular goal amongst people who are interested in eating the tastiest, healthiest food while also being good to the environment. Knowing what’s available in your area at a given time of year is often difficult to determine, so we’ve taken on the task of collecting data from a variety of sources and presenting it all in the most understandable of ways. The Locavore iPhone app will come in handy next time you’re at the market and want to know what’s actually being grown near you, and what is most likely to taste the best right now.

Whether you’re just trying to become more aware of what’s in season around you, or you are fully committed to eating only locally grown food, this app will help you know what your options are.

EatRight is a simple checklist app for the iPhone and iPod Touch that makes keeping track of how many foods from each of the food groups you’ve eaten. However, personnally, I don't believe much in such a measured approach.

Another use of information technologies is to facilitate the unexpected (by the outsiders) gathering of crouds. CarrotMob has imagined how technology could combine with collective consumer action, to favor positive change by companies. Will it work?
