And now we move on to another drug one that is commonly not taken a micro darcis. In many parts of the world alcohol is considered a legal high with a long tradition of wine for example has been cultivated for fisons of years. But like other drugs alcohol has side effects had Alcohol Abuse takes quite a toll on the body. Cant. Move. Afterward some people treat themselves to a beer its relaxing but how exactly does it affect our bodies. After being swallowed alcohol rapidly enters the blood stream most of it via the small intestine. Its then transported throughout the body and inhibits the absorption of nutrients. Within
minutes the alcohol reaches the liver which begins to metabolize it unfortunately the byproduct of this process is more toxic than alcohol itself. In the brain alcohol disturbs the balance between inhibition and excitation it also jacks up the release of feel good hormones like Dopamine Serotonin and endorphins so it first drink is typically become more talkative and outgoing the problem begins when the drinking doesnt stop. The liver can only process one unit of alcohol an hour alcohol its toxic by products damage cells throughout the body. It results in inflammation of the a sophos and stomach and too much drinking can damage d. N. A. In cells making drinkers more susceptible to various kinds of cancers. While the alcohol is being toxified in the liver fatty accumulate there replacing healthy tissue chronic excessive drinking leads to whats called a fatty liver in this Condition Liver Function progressively declines at this stage every drink poses a health risk. Alcohol abuse damages and even kills off nerve cells in the brain in some cases leading to memory loss and Cognitive Impairment meanwhile the liver damage gets worse and worse scars form as cells are being destroyed by continued drinking the final stage Liver Cirrhosis Drinkers dont feel the slowly progressing to seize even if they do sleep off the short term effects. And the impact of chronic Alcohol Abuse can involve social as well as physical problems. Cutting back on alcohol or giving it a mall together its a good idea then if youre lucky your body will start recovering quickly if the damage isnt too advanced fatty liver can regenerate within weeks and inflammation can subside if you stick to the lifestyle but thats no reason to celebrate there will always be a residual impact it may take years for your cancer risk to be reversed if at all. Last report has to do with another kind of substance abuse. Looking at these images you might think wait. Well yes that. But were going to look at quite a different kind of wheat. The kind you dont want to new fields and this was super weeds which of Development Assistance to have
a site one culprit is slender foxtail or black grass its proving a nightmare. This is weed control the easy way Blanket Spraying Fields with herbicides for twenty years thats been an integral part of the job for a Farmer Function to it but using all those chemicals has come at a price the emergence of another unwelcome invader a super weed that towering over his prized wheat. B. C. s you know our folks runs because now this is black grass the main problem is that its spreading like and that can rapidly mean a loss of income of over fifty percent. Of course there are Short Term Solutions in the form of herbicides from the Agro Chemical giants but even they can no longer eliminate black grass for good its now spreading like a plague. And you can see you know well have a grow. Over
a month and if you have three or four hundred of these persuade him either theres no room for the displaced crops or god its very well. As will probably be the case here soon. Together with their barn a man from the regional Farming AuthorityFrank Stewart has been documenting the onward march of this noxious weed the worlds most widely used herbicide for example is proving increasingly ineffective. The central todd habits of life for say it would normally kill everything including black grass so. We now have fields in northwestern germany where its failing in the fight against black rocks this land border. Its shocking to see how the weeds develop such. Wrong resistance of the senses else. Thats resistance that makes the weed practically invincible with superpowers bestowed by human intervention. Random genetic
mutations can lead to a weed becoming resistant to a particular herbicide. Once resistant black grass has infested the field sprayed with that chemical the non resistant plants competing for the space with air and die. The surviving variety then thrives unimpeded leaving c its which in turn produce more resistant black grass weeds that evolved this way and are no longer vulnerable to new herbicides are called super winds. The rapid proliferation of multi resistant weeds has become a global problem. From the Chemical Industry say they might have a new product in ten or fifteen years time it used to be every five or ten years so once black grass had develop resistance to these active ingredients that be something new to replace them that it worked except farmers fail to adapt that
planting system in us on both the state of water and. Until now chemical agents have enabled conventional farmers to grow the most profitable crops now many of them are looking enviously at colleagues they used to mock organic farmers. Weeds grow in their fields too except here theyre not exterminated with chemicals. Organic farmer finer bone for us to use is methods that have proven first full since the dawn of agriculture thats the seeds was are you big this is harry advantage which is a real nuisance during harvest was on the go because but weve learnt to keep it under control through how in. Good time you know we have a lovely clean crop its a minor because its all thanks to mechanical weed control. We called we would have won. Organic farmers are not averse to high tech methods either some now have State Of The Art Mechanical Hose that relieve fields of unwanted visitors there fitted
with cameras g. P. S. And an auto steer function. But some conventional farms have remained resistant to mechanical tillage seeing it as a step backwards from herbicides. And that it was so easy to rig up the sprinkler fill up the tank and just drive the job was over in no time when this would ive always claimed that mechanical options were too expensive and time consuming could hide its fond as it might the greater Efficiency Argument didnt actually wash im finished. So theres more to our gannett farming than just modern technology Finer Bornhorst gets to grips with weeds and other pests without chemical assistance and by following the laws of nature rather than the market he could potentially sell far more of these red potatoes every year but he prefers to rotate and only plant them every four years on the same field of them as it so
often the one on the quality rapidly declines when you grow them too frequently in succession the potatoes become extremely present to disease and past slow and organic farmers cant take much action against them getting conquered so variety and long intervals between planting are the best means of producing nice healthy could take. This best to mr or ms or no and sure to cut off and.
