This document discusses seedballs and their use for environmental conservation. It describes that seedballs are a mini ecosystem that protects seeds from birds, ants and slugs as they germinate. Seedballs are made by mixing soil, manure and water into balls containing 1-2 seeds each. They break down over time as the planted seeds sprout. The document promotes seedball bombing, which is throwing seedballs to introduce vegetation to land in a way that mimics natural seed dispersal. It has hosted thousands of events and involved over 50,000 volunteers working towards sustainability goals like those defined by the UN Sustainable Development Goals.
