Permaculture is a practical design philosophy intended to help us live and prosper in an environment, while working with nature in a positive way, using solutions based on careful observation of natural ecosystems and common sense.
Sprouts are very easy to grow at home. Alfalfa seeds, mung beans, chickpeas and many others provide great nutrition while costing very little and taking almost no time at all to get started.
Soak the seeds / beans in water overnight, then put them (damp) into a clean jam jar and rinse at least every day. They should start sprouting pretty quickly and can be eaten after a few days (at whatever stage you want really). If kept in the fridge once ready, they should keep longer as it slows their growth.
Be aware of salmonella and E. coli: unclean practices and leaving the sprouts too long without rinsing increases the likelihood of getting food poisoning. Keep jam jars clean and rinse the sprouts often.
Afforestation is the establishment of a forest or stand of trees in an area where there was no previous tree cover.
