Entropy increases over time within a closed system. But this is where your garden is an exception. Your garden is an open system which can receive more energy every season. If this weren’t possible, every field on earth would become barren quickly. The universe as a whole may be a “closed” system in which total useful energy is always on the decline, but Earth in relation to the Sun is no such thing. The Earth is constantly supplied with far more energy than it needs. The only question is whether or not we can receive and utilize the inflowing energy.. There is no such thing as a “closed” farm system, nor can there ever be. Even the most self-sufficient farm must depend on energy from space to grow next year’s crop. The only question is whether we have the practical knowledge to harvest all of this precious sunlight and produce new organic matter on our farms.
You can try this yourself, imagining yourself to be a “closed” system, but why would you not avail yourself of the energy of others and the fruits of their experience? Some people promise the moon, but we only promise the better use of the sun. As the stars are the source of all fertility, we want to share our knowledge with you so that you too can become an oases in the age of climate chaos.
