Rudeness in America essays

Rudeness in America essays In my point of view, lack of education on proper behavior and good ethics is the main reason for increasing rudeness in our civilized and educated country. Therefore, the young generation in America doesnt even know the difference between rudeness and kindness. When my family and I moved to U.S. eight years ago, we had to deal with all kinds of rudeness and discrimination the first few years. It seemed like we were hated just for not talking to anybody and for dressing differently. Little kids would call us different names right in front of their parents, and would tell us to go back to Russia even though we came from Ukraine. However their folks, instead of telling them that such behavior is impolite, would just laugh with their kids encouraging them to do it again. Teenagers would kick our apartment door in the middle of the night and then would burst with laughter watching my dad in his pajamas and barefooted, chasing one of them. Even adults, who seem to have some life experience and basic knowledge of proper behavior, would act rudely by parking their cars in our parking space knowing that we wouldnt call the towing company due to a language problem. These and many other examples show how rudeness and even violence can be passed from generation to generation. As a result, rising population who never been taught differently, take this kind of rude behavior for granted thinking that this is the only way to live and survive. They adjust themselves to this kind of lifestyle passing it every day to the people around them, therefore the effects of that could be seen instantly and in a long term. Some people become aggressive, lose their temper, and get into fights over miner misunderstandings. Others, more emotional and who been often rude to, close inside of themselves from the rest of the world, loose their self-esteem and fall into depression, which often leads to either suicide or m ...

Needle Blight Tree Disease - Prevention and Control

Needle Blight Tree Disease - Prevention and Control This group of blight diseases - including Diplodia, Dothistroma and brown spot - attacks conifers (mostly pines) by girdling needles and killing branch tips. These needle blights are caused by the fungus, Dothistroma pini mostly on western pines and Scirrhia acicola on longleaf and Scots pine needles. Needle damage can cause major commercial and ornamental damage to conifers in North America significantly affecting the nursery and Christmas tree industries. Infected needles often fall from the tree creating a symptomatic scorched, denuded look. The blight usually results in dramatic browning and dropping of the foliage beginning on the lower branches. It rarely attacks upper branches on conifers so the tree might not immediately die. Diseased Needle Identification Early symptoms of a blighted needle would be deep-green bands and yellow and tan spots on needles. This deep green color banding is short-lived. The spots and bands quickly turn brown to reddish brown during the summer months. These bands tend to be brighter red and more numerous on pines in California, Oregon, Washington, and Idaho, where this disease is often referred to as the red band disease. Needles may develop extensive leaf browning within several weeks of the first appearance of symptoms. Infection is typically most severe in the lower crown. Infected second-year needles usually drop before infected current-year needles. Needles that become infected the year they emerge often are not shed until late summer the following year. Successive years of severe needle infection can result in tree death. In most cases, the disease makes pines in landscapes unsightly and pines in Christmas tree plantings unmarketable. Prevention Repeated annual cycles of disease infection can result in dead limbs and eventual loss of any meaningful ornamental or commercial value of the conifer. Breaking this infection cycle has to happen to effectively stop the fungus. Brown spot needle blight in longleaf pine is controlled using fire. The use of genetic resistant pine strains or clones has been identified in Austrian, ponderosa, and Monterey pines. Seeds from Eastern Europe have shown high resistance and are currently used to produce Austrian pines for Great Plains plantings. Sources of ponderosa pine seed have been identified as having high resistance and collected for planting in endemic areas. Control High-value nursery and Christmas tree plantings can benefit from chemical fungal control. Early detection is important and high dollar trees may be sprayed as a preventative measure in locations where the fungus is active. A copper fungicide spray program, repeated over several years, will eventually allow new, undamaged needles and branch tips to replace the diseased ones. Chemical applications should begin in spring where the first spray protects the previous years needles and the second spray protects the current years needles. When symptoms of the diseases have disappeared, you can discontinue spraying. Ask your local extension agent for recommended chemicals.
