I am building a permanent library whose subject is sustainability, I can't make money on it, because some of the book are copyrighted... So it is a blockchain storage based PWA offline first webapp that uses Arweave as a storage to permanently store knowledgeable books on the topics of sustainability. The goal of the library is to give PEOP;LE A CHANCE TO SURVIVE IN THIS WORLD BY USING OLD AND RECENT TECHNIQUES THAT ALLOWS us TO LEAVE IN A SUSTAINABLE LIFESTYLE - GOOD FOR US, THE FAMILY, THE EARTH AND THE ECONOMY.
