With the tremendous growth in wind energy in the past decade, turbines often have been planted in or near croplandââ¬âleading both farmers and researchers to wonder what effect the rotating blades might have on corn, soy, and other crops. Some of the leading research is under way in the U.S. Midwest, heartland of the worlds leading corn-producing nation, a place where blustery fields have beenideal for siting wind energy farms. The findings here could apply to many places around the world, wherever turbines and farms are near each other, although the effects on vegetation may vary by region or by crop. 2011 AMONG THE HOTTEST YEARS, Marked by EXTREME WEATHERS An animation still using satellite data shows Arctic sea ice melt during the summer of 2011. This year is shaping up to be one of the ten hottest years on record, according to a United Nations report announced yesterday. Likewise, 2011 may be the hottest year on record during La Nià ±a, a periodic cooling of the eastern tropical Pacific. Thats a bad sign, since La Nià ±a years are generally relatively cool, said Steven Running, a professor of ecology at the University of Montana, who was not part of the studyShow MoreRelatedStandards Of Waste Dumping Of Chemical Industries1303 Words à |à 6 Pagesto solve the environmental problem in the chemical sector. Prevention of waste is meant by use of minimum waste at the source and also reduction in the use of raw materials and energy. Waste dumping standards accepted by industry is most important. Industry seems to assume that waste minimization means only the reduction of the amount of waste sent to landfill, thus any kind of activity, especially off-site utilization and incineration, is seen as waste minimization. An Environmental administratorRead MoreEssay On Cleaner Production948 Words à |à 4 PagesCleaner production Cleaner Production is referred to in the US as Environmental Audits: In the United State of America, Cleaner creation audits is a procedure to create cleaner generation design of specialized, economy and environment feasibly, and discover the reason of high vitality utilization, high material utilization, and contamination.

However, probably and quite certainly, environmental aspects were not considered as a priority back in the 20th century when industries increased their profit by using cheap and efficient resources (compared to other sources of energy) such as coal, oil and gas to supply the energetic demand. Unfortunately, the uncontrolled and unsupervised exploitation of fossil fuels drove mankind to a period of time where climate change is one of the environmental threats humanity will face in a close futureRead MoreHow to Reduce the Amount of Chemicals and Toxins Found in your Home1352 Words à |à 6 PagesFor the first assignment in our contemporary chemistry class, Professor Johana Doe presented us with a question. Give or take a few words, she wanted to know what chemistry meant to each of us. Many of our classmates, including myself, responded to th e proposed question with a not so surprising response. We each reasoned that chemistry meant little or nothing to our lives or us. I always looked at chemistry as a very annoying class that I took in high school that involved beakers and the periodicRead MoreThe Six Branches Of Chemistry1482 Words à |à 6 PagesList and define the six main branches of chemistry ORGANIC CHEMISTRY Organic chemistry involves the study of the structure, properties, and preparation of chemical compounds that consist primarily of carbon and hydrogen. organic chemistry the study of most carbon containing compounds INORGANIC CHEMISTRY Inorganic chemistry is the study of the properties and behaviour of inorganic compounds. It covers all chemical compounds except organic compounds. Inorganic chemists study things such as crystalRead MoreRole of Chemistry in Human Welfare1394 Words à |à 6 PagesChemistryà is theà scienceà ofà matterà and the changes it undergoes. The science of matter is also addressed byà physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties ofà matter, as well as the changes it undergoes duringà chemical reactions.à It is aà physical scienceà which studies variousà substances,à atoms,à molecules,à crystalsà and other aggregates of matter whether inRead MoreChemistry Galvanic Cell1634 Words à |à 7 PagesStage 2 Chemistry Investigation Folio: Practical ââ¬â Galvanic Cell Name: YY Names of Partner: ZZ Part A Investigation Design Proposal: Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current, the greater the flow of current will be produced from the galvanic cell. Independent Variable: ConcentrationRead MoreQuantitative And Quantitative Analysis On Chemical Reactions1401 Words à |à 6 Pageschemical reactions. These same principles can be used to determine limiting reagents. It is important to understand how one reactant can be limiting for environmental and economical reasons. A company reacting precious metals would want to have the metal as the limiting reagent, as to not waste any of the more expensive material. From an environmental standpoint, if one was to neutralize an acid spill in a lake, he or she should use a stoichiometric amount of base as to assure that excess base will
