Glad you asked!
We use bikes to deliver food for a few reasons. For one, it’s (much) cheaper, which makes it so that we can afford to do more quick, direct deliveries. This enables us to deliver more healthy food like fresh produce rather than canned foods, etc. Sometimes when the food rescue scale gets too big, there is actually more waste because the perishable food slips through the cracks.
Also, some of the communities we partner with are some of the most polluted in the country. In 2016 we saved an estimated 8 tons of CO2 emissions by biking!
Aaaand biking is more fun! It makes volunteer solicitations and outreach easier because people are looking for a practical way to exercise plus they don’t need a car to participate (but some volunteers use cars too, and that’s ok!).
