One of the ways to understand our natural environment is to divide the earth into four kingdoms: the human kingdom, the animal kingdom, the vegetable kingdom and the stone kingdom.
If we start with ourselves, we form the human kingdom. We humans depend on the three other parts for our survival. First, the animal kingdom. Even if we don’t use animals or animal products for food, we still need them. Just think of bees, which are necessary for pollination and thus sustain life.
Both animals and humans depend on the plant kingdom – all plant life on Earth – for survival. We need plants for the fuel and building materials that give us energy and enable growth. In addition, there are vitamins, which humans and animals can produce themselves to a small extent. But for the most part, both humans and animals depend on the vitamins formed by plants.
The same also applies to the necessary fatty acids, which essentially originate in the plant world, for example in algae. Phytonutrients are a category of essential substances that, as the word phyto implies, only occur in plants and that keep the human body healthy and protect against all kinds of chronic diseases.
And finally, there are the minerals. Minerals come from the rocks of the earth and consist mainly of metals. From the stone kingdom, minerals also end up in the seawater and in the air. Minerals are in the soil and are absorbed and utilized by plants. From there, animals and humans absorb the minerals. Unlike certain vitamins and fatty acids, it is impossible to make minerals yourself. Our body consists of about 4% minerals. They are necessary for all processes that keep the body going. They also have a key function to make vitamins effective.
