The best community project people could ever undertake is to make sure every resident have their share of various fruit trees and berry bushes suitable for their area and climate. People will always have food available in case of an emergency. By putting the various trees on EVERYONE's properties and even in the nearby wooded areas will guarantee plentiful fresh food.
Have a green thumb? Make sure that friends and neighbors all have their fruit trees and berry bushes. Start planting them. Continue by planting extra plants and trees in the wild, so that someday, someone will happen upon them. No pesticides. Keep them organic.
Buy organic fruit trees and bushes and start planting for your fellow brothers and sisters.
Every landlord and property owner should consider this for their rental properties, and WITHOUT charging extra.
