Just for the record, I worked in agriculture in Zambia and Zimbabwe for about 18 months in the early 1990’s. Tobacco was just another crop.
At that point in time, everyone smoked, tobacco sponsorship was everywhere, hamlet cigars where advertised on the TV, Camel Trophy sponsored Landrover, multiple different brands sponsored F1. People smoked on trains, planes, in the tube, in the pub, in offices and in hospitals. Menthol cigarettes were sold to clear your lungs.
I was offered a very well paid job with Phillip Morris, but turned it down. I didn’t like the way the industry behaved.
Tobacco smoking other in your own home is now pretty much banned in all public spaces, and has been for 15 plus years. It is banned so that others don’t have to suffer from second hand smoke.
More recently I have been involved with technologies to produce large molecule drugs within tobacco plants that are biosimilar to many very expensive cancer drugs, in particular Herceptin. These are mostly produced in animals cells in very expensive bioreactors. Use plants dramatically reduces the manufacturing costs of such drugs, so making them much more accessible. These are now in clinical trials.
As regards lead, there has long been evidence of how dangerous and harmful to biological processes it actually is. Long ago lead was banned for use in food packaging, as a food ingredient, use in solders for water supplies and in any form of water pipes. Lead pipes in old houses are still there. Like asbestos, this causes difficulties when trying to any works or to sell the property- it all has to be disclosed. Lead is no longer used in household products, paints, industrial processes etc.
There are very strict regulations on lead content in slurries, fertilisers etc etc.
Yet many on SD are just whining that its against their rights that they are being banned from spreading one of the most toxic substances known to man around the countryside. The government has in my view made the correct decision in banning lead from ammunition. There are perfectly viable alternatives that work for 99% of guns in use. If you really want to continue a 100 plus year old damascus barreled shotgun then buy bismuth cartridges and savour each shot. If you are using a muzzle loading rifle, experiment with patched monolithic bullets, or just stick to shooting on an approved rifle range.
By removing lead, shooting is cleaning up its own house and removing one of principle objections of the anti brigade. When you shoot lead cartridges, that lead is no polluting the wider environment and not just yourself.
