Once those basic needs are fulfilled, you're ableto survive.``````Early human beings lived in a survival mode, and they lived through floods and earthquakes, droughts and volcanoes. Without a single penny to spend, they had all they needed to live long enough to reproduce. This mode of production is called foraging, and although it was once very common it is very unusual today.If survival is the goal for you and all the people around you, you don't need to go far to find what you need. There are animals in the woods you can hunt. There are berries and roots growing in the ground. You can build a hut of sticks and mud and drink water from the stream. Clothing can be made from skins and leaves, all of which can be acquired freely. You don't
need money, you don't need to compete for space or goods, and all the people have equal access to all they need.Foraging requires nothing of the land. People take what they need and no more. They make no new products and produce no litter or pollution. Foraging is a way of life that allows the natural world to renew itself.AgricultureHuman nature is all about change and growth, and over time people have learned to want - and get - more than they need to merely survive.
