I feel like these guys do it better…
Freeganism started in the mid 1990s out of the anti globalization and environmentalist movements. It is generally associated with an anti- consumerist ideology and other alternative life styles. Freeganism is the practice of reclaiming food, clothing, and other items that have been thrown away. Their entire lifestyle is based on limited participation in the economy and minimal consumption of resources. They relay largely on community, freedom, cooperation, generosity and sharing.
To get food Freegans participate in dumpster diving, plate scraping, wild foraging, gardening, and bartering (and other noncapitalist ways to obtain food).
Through dumpster diving good condition food can be found in the dumpsters at super markets, and restaurants simply due to it approaching a ‘sale by date’ marker (come on we all know that not all the food that reaches this date is bad). The idea behind doing this is that this food will not go into landfills and by them eating the waste there is more better quality food to go towards the hungry. Additionally as mentioned before they can acquire tools and clothing this way too.
Freegans understand the risks of dumpster diving and have precautions while doing it such as using poles to shift though garbage bins instead of their hands, as well as cleaning of food before consumption.
It’s not uncommon for freegans to live ‘off the grid. Sometimes freegan have their own communities and have community gardens where food is grown and shared.
Housing can also be scavenged for some Freegans.s Squatting is not an uncommon practice. This is when someone who doesn’t have the legal rights to a property lives there.
To learn more you can read up on the Freegan website (apparently manufacturers throw away laptops and Wi-Fi towers too…) http://freegan.info.
This site has an awesome video at the bottom
Again here is another video.
And for those who would like to look into it more I believe there is a documentary on Netflix
