Biodiversity
In the topmost layer of soil covering the Earth, what we might call ‘the Mother’s delicate skin, a multitude of micro-organisms combine with organic matter to feed plants in a metabolic process energised by the sun.
Below the top organic layer, the subsoil anchors the plant’s roots while they tap into the soil’s nutrient cycle.
And below that is the bedrock, the backbone of the Earth. With its different layers of soil the Earth rotates around the sun creating seasonal changes and climatic diversity, leading to diverse ecosystems with diverse species living together interdependently according to the biochemical laws of nature. From here a carbon stock contained in plants, bacteria and algae is formed from CO2 absorbed from the atmosphere.
In less than a century, from the ‘Green Revolution’ in the 1960s to now, humans have turned the Earth, the only home to all living things including humans, into a object of exploitation and destruction. The Mother’s skin has been poisoned as agriculture has turned from ecologically sound traditional practices to the chemically driven industrial production of hybrid and genetically modified species, with her body used as a dumping ground for industrial wastes. All this in the service of non-stop competition for GDP growth. Now with the interdependent harmony of the Earth thoroughly undermined humans are waking up to their mistake and trying to re-embed a greener economy to help save the Earth.
Economy
An economy can be understood as the sum of the energy, materials and information with which human impact the attributes of natural resources in order to create tangible products for human use. Economies are run by each nation depending on their perception of economic value. Above all, their perceptions of the economic value of land and labour, the two fundamental factors of every economy in which four pairs of categories
