barchid, not MARS but very important to the topic of Covid. Apologies in advance to BB readers.
As a qualified Botanist, plant diseases have been prevalent and chemically controled since the 1960's. Plant breeders have tried to keep ahead of emerging diseases but have relied more and more on Chemical controls which have needed to advance. The potency of early chemicals lasted maybe 10-15 years until natural forces ( disease mutations) became resistant. The cycle of Plant breeding and Chemical resistance continued for almost 50 years until Breeders and Pathologists became aware the process was becoming unsustainable. A lot of head scratching until scientists at Cambridge and elsewhere observed from archived repositories of cereal varieties, that old varieties were are resistant to diseases now being seen in newer varieties. In essence and to some degree confirming Darwin and survival of the fittest, it became clear varieties which had developed over many generations, often in the wild, were stronger and very much more resilient. Breeders then began to use genes from the ancient varieties to provide levels of resistance. This has been successful to some degree. Do'nt confuse this use of genes with Genetically Modified (GM) which basically uses genetic material from other plant species. There is a significant difference.
The reason behind this illustration is to show how the Natural world can be manipulated by Man, but ultimately Nature will win. The current Pandemic will only go away when it is allowed to run it's natural, not what many want to hear for good reason. Can Man as a specie continue with perpetual controls over how we live our lives?
Here endeth the Sermon, and apologies to those who will disagree.
Back to MARS, how £6000 per pub is going to offset costs and provide profit is quite bewildering. It will help certainly and the small village pub ( if there are any left) managed by husband and wife may find some profit but not the big drinking houses with staff, power bills etc.
