Life on land
We live on a planet where agriculture covers ∼38% of the land surface. Humans strongly depend on the capacity of soils to sustain agricultural production and livestock, which contributes more than 95% of global food production.
The bad news is that at current rates of soil destruction (i.e. decarbonization, erosion, desertification, chemical pollution), within 50 years we will not only suffer serious damage to public health due to a qualitatively degraded food supply characterized by diminished nutrition and loss of important trace minerals, but we will literally no longer have enough arable topsoil to feed ourselves.
The good news is that regenerative agriculture, a conservation and rehabilitation approach to food and farming systems, focuses on topsoil regeneration, increasing biodiversity, improving the water cycle, enhancing ecosystem services, supporting biosequestration, increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Practices include recycling as much farm waste as possible, adding composted material from sources outside the farm, and holistic management of grazing and livestock.
