We are now guided by telluric and biodynamic forces, and by traditional knowledge. Our ancestors flew<span class=\"Apple-converted-space\">\u00a0<\/span>in wondrous flying machines \u2013 read the Ramayana. The region of \u201cPanchaaba\u201d (modern Panjab)<span class=\"Apple-converted-space\">\u00a0<\/span>was the granary of Jambudveepa and<span class=\"Apple-converted-space\">\u00a0 <\/span>the ancient<span class=\"Apple-converted-space\">\u00a0 <\/span>world. Traditional agriculture fed our people who were free of disease and lived to the age of Methuselah. Our ancient engineers knew how to send water even up against gravity.<span class=\"Apple-converted-space\">\u00a0 <\/span>They built a bridge across the Palk straits. Our ancients knew about organ grafting, even creating Ganesh by grafting an elephant&#8217;s head onto a human. Didn&#8217;t the Mahabharata mention a woman who gave birth to 100 children?<span class=\"Apple-converted-space\">\u00a0<\/span>This is evidence of advanced reproductive technology and<span class=\"Apple-converted-space\">\u00a0 <\/span>stem-cell research done thousands of years ago by our ancestors\u201d. All this and more were asserted at the annual<span class=\"Apple-converted-space\">\u00a0<\/span>Indian Science congress in January, 2019.<\/p>\n<p>The plight of the space rocket heading towards disaster mimics the current state of the planet. The threat of global warming gives only a decade more for corrective action. Even those who are skeptical of man-made global warming agree that the burning of fossil fuels and the resulting noxious emissions<span class=\"Apple-converted-space\">\u00a0<\/span>must stop.<span class=\"Apple-converted-space\">\u00a0<\/span>The<span class=\"Apple-converted-space\">\u00a0<\/span>rapid reduction of biodiversity has perhaps five to ten decades more for corrective action. Scientists find<span class=\"Apple-converted-space\">\u00a0 <\/span>that a human-caused sixth mass extinction of species is now underway. Vertebrates<span class=\"Apple-converted-space\">\u00a0 <\/span>on land and<span class=\"Apple-converted-space\">\u00a0<\/span>sea are threatened globally by<span class=\"Apple-converted-space\">\u00a0<\/span>human activities. The proportion of insects in decline is twice as high as for vertebrates. The insect extinction rate is eight times faster than for<span class=\"Apple-converted-space\">\u00a0<\/span>mammals, birds and reptiles (Sanchez-Bayo et al, 2019, J. Bio. Conservation). Insects play a profound role in Earth ecosystems. They are critical pollinators who also recycle nutrients into the soil. Meanwhile, the clogging up of the oceans with more plastic<span class=\"Apple-converted-space\">\u00a0 <\/span>than all the weight of the fish may happen<span class=\"Apple-converted-space\">\u00a0 <\/span>in just<span class=\"Apple-converted-space\">\u00a0 <\/span>three decades!<\/p>\n<p>What drives this menacing trend? When did this dive towards<span class=\"Apple-converted-space\">\u00a0<\/span>the apocalypse begin? The menacing trend can be reversed, but not by nostalgically going back to the limited methods of the past.<\/p>\n<p><b>How the menace began with the rise of large scale slavery<\/b><\/p>\n<p>This menace began<span class=\"Apple-converted-space\">\u00a0 <\/span>in the 19th century<span class=\"Apple-converted-space\">\u00a0 <\/span>with millions of shackled humans from Africa transferred<span class=\"Apple-converted-space\">\u00a0 <\/span>to the Southern USA, and to the colonies of Europe. Slaves were forced to create a huge monoculture of cotton covering vast territories. The ships of the British empire burning coal brought the US cotton to feed the textile industry of Lancashire and the industrial revolution. British coal as well as other mining ensured complete habitat engulfment by human activity making UK one of the most polluted lands, even today, as shown by the map of soil cadmium in UK<span class=\"Apple-converted-space\">\u00a0 <\/span>compared to continental Europe. Most of the cadmium toxins came from the mining and use of coal.<a href=\"https:\/\/www.colombotelegraph.com\/wp-content\/uploads\/2019\/02\/Map-of-total-Cd-content-in-European-soils-.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-199104\" src=\"https:\/\/www.colombotelegraph.com\/wp-content\/uploads\/2019\/02\/Map-of-total-Cd-content-in-European-soils-.jpeg\" alt=\"\" width=\"477\" height=\"408\" srcset=\"https:\/\/www.colombotelegraph.com\/wp-content\/uploads\/2019\/02\/Map-of-total-Cd-content-in-European-soils-.jpeg 644w, https:\/\/www.colombotelegraph.com\/wp-content\/uploads\/2019\/02\/Map-of-total-Cd-content-in-European-soils--300x257.jpeg 300w\" sizes=\"auto, (max-width: 477px) 100vw, 477px\" \/><\/a><\/p>\n<p>We do not have a similar adequately authenticated map for Sri Lanka.

British agriculture in the UK, and in the cotton, potato and wheat fields of America used \u201ctraditional agriculture\u201d, using slaves or<span class=\"Apple-converted-space\">\u00a0 <\/span>surfs. Extremely dangerous but traditionally accepted pesticides like arsenites,<span class=\"Apple-converted-space\">\u00a0<\/span>copper sulphate and cyanide, as well as plant products from Chrysanthemums (as pyrethrins), or Neem-family<span class=\"Apple-converted-space\">\u00a0 <\/span>products (as azadiractins) were used in large amounts, as is needed<span class=\"Apple-converted-space\">\u00a0<\/span>for them to be effective, but hurting the environment. <span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>The industrial revolution in Europe was also driven on the backs of the colonies and slavery.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Southern Europe cut its forests for fuel while northern Europe turned to coal as well.<span class=\"Apple-converted-space\">\u00a0 <\/span>Pollutants in European soils consist mostly of high levels of cadmium, arsenic and such heavy metal toxins. These<span class=\"Apple-converted-space\">\u00a0 <\/span>likely came from the coal-powered economies and mining during the industrial revolution. So, although attempts have been made to link soil cadmium with contamination from modern-day mineral fertilizer usage, quantitative modeling shows this to be completely<span class=\"Apple-converted-space\">\u00a0 <\/span>false (see:<span class=\"Apple-converted-space\">\u00a0 <\/span>J.

Pristine forests in the colonies were also burnt and<span class=\"Apple-converted-space\">\u00a0 <\/span>converted to plantations for<span class=\"Apple-converted-space\">\u00a0 <\/span>cash crops and transported to European markets. Transportation of invasive species occurred, further threatening biodiversity. <span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>The discovery of mineral fertilizers<span class=\"Apple-converted-space\">\u00a0 <\/span>where a few spoons could do the work of many sacks of traditional fertilizer came at the end of the 19th century and amazed farmers. This was quickly followed by the discovery of the Harber-Boshe process<span class=\"Apple-converted-space\">\u00a0 <\/span>in the first years of the 20th century for exploiting atmospheric nitrogen converted to urea. This was probably the most far reaching discovery of modern agriculture. <span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p><b>The discovery of DDT and modern pesticides<\/b><\/p>\n<p>This extreme assault on<span class=\"Apple-converted-space\">\u00a0 <\/span>pristine environments by habitat encroachment via human activity created enormous mono-cultures of cotton, wheat, potatoes, soya, coffee, tea and tobacco, starting from the 19th century.<span class=\"Apple-converted-space\">\u00a0<\/span>This<span class=\"Apple-converted-space\">\u00a0<\/span>inexorable attack on<span class=\"Apple-converted-space\">\u00a0<\/span>biodiversity<span class=\"Apple-converted-space\">\u00a0<\/span>happened<span class=\"Apple-converted-space\">\u00a0<\/span>on a global and<span class=\"Apple-converted-space\">\u00a0<\/span>imperial scale. Such monocultures<span class=\"Apple-converted-space\">\u00a0<\/span>became a necessity to feed the increasing populations as well as the labour forces<span class=\"Apple-converted-space\">\u00a0 <\/span>in the colonies, and<span class=\"Apple-converted-space\">\u00a0<\/span>at home. Governor Ward in British Ceylon realized that the Malabar<span class=\"Apple-converted-space\">\u00a0<\/span>\u201ccoolies\u201d<span class=\"Apple-converted-space\">\u00a0<\/span>(slaves except in name) brought to work in the Tobacco and Coffee plantations will have to be fed.

However, although only<span class=\"Apple-converted-space\">\u00a0 <\/span>incredibly small amounts of these pesticide were needed, farmers deployed what they were used to, and created the \u201cSilent Spring\u201d recorded by Rachel Carson.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Bambaradeniya<span class=\"Apple-converted-space\">\u00a0 <\/span>writing about bio-diversity in Rice fields states that \u201cmost biotic communities in the rice field ecosystem are able to react physiologically and\/or behaviorally to the drastic conditions in these temporary wetlands. As they possess the ability to recover rapidly from various disturbances, including chemical inputs, these organisms could be interpreted as biota with high resilience stability\u201d (Bambaradeniya, Ph. D Thesis, 2000). The widely accepted in-soil indicator organisms are the earth-worms (<i>Eisenia fetida and E. andrei<\/i>), the springtails (Folsomia), the mite (<i>Hypoaspis aculeifer<\/i>) and microorganisms that transform nitorgen (Ockleford et al., 2017).<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>In contrast, <a href=\"https:\/\/www.colombotelegraph.com\/?s=%22Ranil+Senanayake%22\"><strong>Ranil Senanayake<\/strong><\/a> (RS), a<span class=\"Apple-converted-space\">\u00a0 <\/span>Forestry<span class=\"Apple-converted-space\">\u00a0 <\/span>ecologist<span class=\"Apple-converted-space\">\u00a0 <\/span>seems to unreasonably claim that<span class=\"Apple-converted-space\">\u00a0<\/span>in Sri Lanka the egrets that flock to the farmer&#8217;s plough are<span class=\"Apple-converted-space\">\u00a0 <\/span>just \u201cresistant species\u201d eating \u201cresistant earthworms\u201d.<span class=\"Apple-converted-space\">\u00a0<\/span>Egrets are not known to become resistant to pesticides. They simply die of them or become debilitated<span class=\"Apple-converted-space\">\u00a0 <\/span>if toxic amounts are consumed. Perhaps RS meant \u201cresilient\u201d and not \u201cresistant\u201d. If the \u201csilent spring\u201d is any indicator of ecological doom, \u201cflocking of birds \u201d to eat earthworms and other grubs, are a necessary (but not exhaustive)<span class=\"Apple-converted-space\">\u00a0 <\/span>sign of a<span class=\"Apple-converted-space\">\u00a0 <\/span>live, highly resilient soil ecology. Similarly, Wickramasinghe et al (J. Appl. Ecol. 2003) had used visitations by bats, and also nocturnal insects (2004)<span class=\"Apple-converted-space\">\u00a0 <\/span>to compare the health of conventional and organic farm plots. Such experiments confirm what is <i>a priori<\/i> reasonable<span class=\"Apple-converted-space\">\u00a0 <\/span>i.e., <i>lower-intensity farming,<span class=\"Apple-converted-space\">\u00a0 <\/span>or going right back to a hunter-gatherer approach is best for biodiversity but worst for feeding humanity.<\/i><\/p>\n<p>It took decades to appreciate the negative long term effects, as well as the power of DDT in eliminating good insects as well as bad insects.<span class=\"Apple-converted-space\">\u00a0<\/span>DDT itself was banned in 1974 but re-approved by the WHO in 2006<span class=\"Apple-converted-space\">\u00a0 <\/span>only for domestic use.<span class=\"Apple-converted-space\">\u00a0 <\/span>The new pesticides at last freed the farmer from being a slave<span class=\"Apple-converted-space\">\u00a0 <\/span>to the soil as he\/she could now farm thousands of hectares almost \u201csingle-handedly,\u201d and have time for leisure and life, using pesticides, fertilizers and farm equipment instead of vast amounts of human labour and massive mounds of compost.<\/p>\n<p>The introduction of these methods, constitute the basics of the green revolution and went hand in hand, albeit often in hindsight,<span class=\"Apple-converted-space\">\u00a0 <\/span>with new legislation to control the use of pesticides. The acute and chronic toxicity data for pesticides, coal burning, industries and<span class=\"Apple-converted-space\">\u00a0<\/span>mining were determined and globally introduced by national authorities.<span class=\"Apple-converted-space\">\u00a0<\/span>They were guided by<span class=\"Apple-converted-space\">\u00a0 <\/span>the WHO and the FAO data for legislating safe usage of environmentally acceptable agrochemicals. That was \u201cmission control\u201d telling the pilots what to do.<span class=\"Apple-converted-space\">\u00a0<\/span>Ecosystems gradually recovered when these rules were followed.<span class=\"Apple-converted-space\">\u00a0<\/span>Salmon and sea trout<span class=\"Apple-converted-space\">\u00a0<\/span>returned to the river Thames<span class=\"Apple-converted-space\">\u00a0<\/span>by mid 1980s.<\/p>\n<p>And yet, the fear that pesticides are poisoning the food we eat<span class=\"Apple-converted-space\">\u00a0 <\/span>has increasingly gripped a technologically unprepared public. Low-intensity farming (e.g., organic farming) will require massive habitat encroachment and extensive water resources to yield enough food for everyone, adding to the assault on the ecosystem.<span class=\"Apple-converted-space\">\u00a0<\/span>Even without such an assault, an<span class=\"Apple-converted-space\">\u00a0 <\/span>anthropogenic mass extinction has arrived in<span class=\"Apple-converted-space\">\u00a0 <\/span>response to<span class=\"Apple-converted-space\">\u00a0 <\/span>an over-populated planet.
