Today marks Earth Overshoot Day, the day in the calendar when humankind has already used up the equivalent of a year’s worth of natural resources. It marks our continuing failure to adapt towards a more sustainable pattern of existence. When Overshoot Day was first calculated, back in the mid 1980s, it fell on 19 December. Although in recent years the rate of acceleration has decreased (last year Overshoot Day fell […]
It is something which is at once amazingly powerful and yet incredibly fragile. Without it we would not exist. Indeed, without it there would be no life on Earth. What is it? Soil. The living skin of planet Earth. This thin, fragile layer on the surface of our planet is literally teeming with life. Grab a small handful of soil and what you hold in your hand will contain more […]
In 1804, the total population of the human race on planet Earth finally reached one billion. It took a further 123 years for it to reach 2 billion. From there, to reach 3 billion took just a further 33 years. It hit 4 billion 14 years later, 5 billion after another 13, and 6 billion after another 12. That was at the turn of the 21st century, and now we […]
The switch to industrial-scale, chemical dependent agriculture which began in earnest at the end of the Second World War is often incongruously referred to as the green revolution. At the heart of that revolution was the use of chemicals, and artificial fertiliser in particular, to boost crop yields. It is no coincidence that the green revolution coincided with the end of the war. With the domestic military war effort suddenly […]
Healthy soil is fundamental to successful organic farming and gardening. If the soil is healthy, microbes and other soil organisms will thrive, and in turn will naturally decompose organic matter and harness nitrogen from the atmosphere, converting it into organic form. For the organic gardener there are a variety of ways to create and maintain a healthy soil. Many, like me, rely principally on compost generated from waste vegetable matter. […]
Many of the processes that are vital for life to flourish on this planet are dependent on interactions between living things, such as plants and micro organisms, and inorganic entities, such as the air, the oceans and the soil. Collectively, these interactions regulate the composition of the Earth’s atmosphere as well as its temperature, the fertility of its soil and even the salt levels in its oceans. The Gaia Hypothesis, […]
