Jet contrails do produce “global dimming” which reduces global warming but, in the process, produce enormous amounts of CO2. That can be removed in enormous quantities actually quite easily.
In the 24 June issue of New Scientist, Ed Hawkins, University of Reading, UK, and Alan Robock, Rutgers University, New Jersey, USA, both are quoted as observing that we really do need, urgently, to invent a way to remove Carbon dioxide from the atmosphere on a huge scale.
The classic way of solving a problem is to find a mirror image problem and put the two together. Link farming (globally we need more food) and urban waste production (as global population and wealth rise, we get more unban waste) in the right way and that could deliver the invention. Well, we already have it and it has been done and on a scale that could be applied globally.
We have the power and the technology. Do we have the micro components?
Common sense tells us that if we use manufactured mineral fertilisers to produce food, eventually, the soil store of trace elements will decline, followed by a decline in the harvested crop, followed by a decline in the health of th4e crop, followed by a decline in the intake of trace elements by humans, followed by a decline in the health of humans.
This common sense understanding of the loss of micro-nutrients in human diets has been shown many times and, again, recently by a paper on soil Selenium decline by Steve McGrath et al and reported in the current edition of The Auger, journal of the British Society of Soil Science.
A normal pond? Not quire – note the white colouration of the water, This is spent drilling fluid from drilling through chalk to bring cables off the North Sea wind farms.
The attached below link is to the Dutch drilling company, VSH website. The pictures (scroll down a bit) are of the drilling operation bringing cables off the North Sea wind farms to the site at Holt in North Norfolk. This brings renewable energy to the UK consumers. What Land Research does is to take the cuttings and spent fluids from such operations and re-use them, usually on agricultural land to replace the 2.5 million tonnes of top soil which the UK loses by wind and rain erosion, down into the sea, every year. Renewable energy with zero waste from such construction operations.
Municipal waste on its way to Frog Island on the Thames estuary There is enough waste in western society, to fertilise enough crop,s to feed western society,
The UN warning of 3 million people facing what will for most of them be unavoidable starvation and death is not new. Malthus predicted it in 1798 and we have been doing a bit since then but not enough. If you are comfortable, why do anything at all about it? In any case, as an individual, what you do is insignificant.
An international consequence is that empty bellies always lead to war. In the history of the world, that has always been true. Could we fill bellies globally? Technically, the answer is yes, we can. Military conflict often gets in the way. Political will in developed countries always gets in the way. It is almost a lifetime away that Bob Geldoff stood up in the EU Parliament and observed that the situation of global hunger and the plenty of Western counties was “obscene”. It is now worse.
How do we fix it? Simply use urban wastes to fertilise land and grow better crops. It has been done in the UK and Egypt, and lots of other places. We need to scale it up and urgently. It would save a lot of imports in the UK, too, The environment would be better off, See “Survival”.
Urban waste could, safely, be sufficient fertiliser to feed the people who made the waste in the first place. If we do not do this, soon, then, logically, the human race will die out.
Nearly all we have came from the land and must eventually go back. Nearly all municipal wastes, including sewage, will make good compost and good compost can be used to reclaim the desert and make arid land productive. “Nearly all” does, of course, mean some exceptions such as lead or Cadmium-based batteries. However, many hydrocarbons and plastics are bio-degradable provided the right process and the right bugs are available in the bio-population or can be added. (Mealy bug larvae will live and multiply quite happily on expanded polystyrene.) Sewage is a great source of nutrients and micro-organisms for a successful bio-process. Of course, testing and controls are a necessary part of a professional operation but it really is true that most urban waste scan safely be used to make enough fertiliser to feed the people who made the wastes in the first place. That is sustainability. The challenge is to get the instruments of governments to understand and find a way of constructive regulation. Soon rather than somewhen.
Oh, and by the way, composts will absorb and hold between 5 and 16 times their own weight of water. That might be useful in creating jobs in upland composting in Cumbria, Lancashire, and anywhere in the upland catchment areas for any of our rivers running through urban areas, including London.
“Survival – Sustainable Energy, Wastes, Shale Gas and The Land” by Bill Butterworth, published by Land Research, has just been released and is available in paperback from good bookshops or Amazon on the web as paperback (at around £10) or electronic version (at only £2.46) for computer or Kindle.
According to UN sponsored research, I tonne of N nutrient, made in a modern, efficient USA fertiliser factory, typically takes 21,000 (yes, twenty one thousand) kWh to manufacture and deliver to farm. Yet, we lose around half to groundwater with rain or irrigation. This will dramatically affect how we farm. Part of the answer is to recycle waste to farm land. How to do this safely and how doing this can also reduce irrigation need by up to 90 % is detailed in a referenced work on sustainable agriculture. All these and how the global population will reach crisis, and when, can be downloaded for free on the Sunday 12 Feb. Search Survival” by Bill Butterworth Amazon.
