" Inextricably linked to the climate emergency is a broader environmental crisis. A third of the Earth’s land is now acutely degraded, with fertile soil being lost at a rate of 24 billion tonnes a year through intensive farming.[19] Generating three centimetres of top soil takes 1,000 years, and, the UN said in 2014, if current rates of degradation continue all of the world's top soil could be gone within 60 years.[20] 95% of our food presently comes from the soil. Unless new approaches are adopted, the global amount of arable and productive land per person in 2050 will be only a quarter of the level in 1960. The equivalent of 30 football pitches of soil are being lost every minute. Heavy tilling, monocropping multiple harvests and abundant use of agrochemicals have increased yields at the expense of long-term sustainability. Agriculture is actually the number one reason for deforestation. In the past 20 years, agricultural production has increased threefold and the amount of irrigated land has doubled, often leading to land abandonment and desertification. Decreasing productivity has been observed, due to diminished fertility, on 20% of the world’s cropland, 16% of forest land, 19% of grassland, and 27% of rangeland. Furthermore, tropical forests have become a source rather than a sink of carbon.[21] Forest areas in South America, Africa and Asia – which have until recently played a crucial role in absorbing GHG – are now releasing 425 teragrams of carbon annually, more than all the traffic in the US. This is due to the thinning of tree density and culling of biodiversity, reducing biomass by up to 75%. Scientists combined 12 years of satellite data with field studies. They found a net carbon loss on every continent. Latin America – home to the world’s biggest forest, the Amazon, which is responsible for 20% of its oxygen – accounted for nearly 60% of the emissions, while 24% came from Africa and 16% from Asia. Every year about 18 million hectares of forest – an area the size of England and Wales – is felled. In just 40 years, possibly one billion hectares, the equivalent of Europe, has been torn down. Half the world’s rainforests have been razed in a century and they will vanish altogether at current rates within another. Earth’s “sixth mass extinction”[22] is well underway: up to 50% of all individual animals have been lost in recent decades and almost half of land mammals have lost 80% of their range in the last century. Vertebrate populations have fallen by an average of 60% since the 1970s, and in some countries there has been an even faster decline of insects – vital, of course, for aerating the soil, pollinating blossoms, and controlling insect and plant pests.
