...Global Warming: A Global Threat Over the period within which human beings have existed, man has been in the forefront of all technological marvels to date. Man has created, destroyed and revived many natural cycles and dynamics that balance the delicate nature of this world. Although global warming is not a recent phenomenon, very few people had knowledge of its existence a decade ago. However, in the last few years, the media started to shed light into the dangers of global warming, and the idea has finally begun to enter the minds of past and the current generations alike. Global warming poses a great danger to planet earth. A harmonious blend of living organisms, human beings and the ecosystem is on the verge of being unbalanced. Within a matter of a few years, the world’s sea levels have risen, animals have become extinct and the delicate balance of nature has almost tipped off. Whether this is a danger to planet earth, is still uncertain, but whatever the effects of global warming may be, there is no doubt that the consequences are going to be massive. Disputes over this topic have reached a boiling point and people and scientists on both sides of the line have begun to wonder if they are right or wrong. Global warming poses a grave danger to man in the form of diseases, food shortages and economic decline. One of the first and obvious dangers of global warming is the effect on human beings in the form of diseases. Diseases are the biggest killers that the world has ever...

...Bugs: The new super food! Eating gourmet insects can save the planet By Alexander Ørum November 23, 2011, Sunday Times A global solution: Global warming is a worldwide threat to us all, and one of the biggest reasons that it has come this far is the way we eat. Farming dairy and the whole agricultural environment is actually one of the main reasons that we produce all this green house gases. The animals are the cause of this problem, and it also produces a lot of Co2 by feeding and slaughtering them. The world’s population is set to rise above seven billion, and we need a new food source to keep on going. We now have a solution; Bugs! Many people see this as a potential substitute for meat and to the future food shortages. To take a historical view on this, humans actually ate insects before we were able to create tools to hunt animals. It is a bit funny when you think of it, that we now have to go back to the way we lived thousands of years ago because of the way we are destroying our own planet through meat. Nutrition: It can be a problem to get people to eat it; actually we are very conservative when it comes to food, we only eat a handful of the seven million different animals which exist on this planet. But the little ones do have some advantages, they contain a lot of the nutrition we need in a day. It can actually replace meat because of its nourishment. It contains protein, amino acid, fiber, iron, calcium and vitamins. So it’s very healthy for you...

...Classic reported revenues of $550 million in it’s U.S. domestic sales, however in September 2006 Chief Marketing Officer Brandon Miller released Classic’s plan to introduce a new line of insect repellent clothing in order to increase gross margins. After conducting a SWOT analysis with the information provided, some of the following strengths of Classic’s were identified; - Classic is identified as the #2 player in casual knitwear sector w/ 16.5% market share. - Low production cost w/ offshore production - Moderate cost advantage over U.S. w/ high volume low-SKU production *more strengths listed in the appendix. Having such a strong and stable stance in the knitwear market is a huge benefit for Classic, and will only increase the chances for success when introducing their new line of insect repellant clothing. Although Classic has many strengths, one of the companies weaknesses is that CEO Robert Ortiz “perceived too much risk in foreign markets. “ pg 1. This fear of expanding the company may prove detrimental to the launch and success of the new clothing, being that countries such as Africa have such a high rate of insect related diseases. Ignoring the potential growth possibilities in foreign markets may severely undercut Classic’s prospective gross margin enhancement. Problem Definition The main dilemma that Classic faces is their lack of brand recognition among their private label/unbranded knitwear. The lack of brand...

...Earth 1200 One of the biggest problems facing the world today is global warming, as many scientists believe that our production of carbon dioxide along with other greenhouse gases are having a heating effect on the atmosphere. This essay will examine the problems of global warming and the dangerous affects that it has for human life along with explaining or possible future. In the documentary Earth 2100, you follow along with Lucy an animated character who describes her life during the global warming timeline that scientists believe will be the sixth extinction. She explains key problems that could happen and will affect our future if we don’t change. The first is a raise in temperature; due to the emitted gases by power plants, automobiles, deforestation and other sources that are warming the planet up. Living on the assumption that oil will be plentiful forever and increase in gas prices leaves people moving out of suburbs and into cities to save money. With a shock to the economy with rising food prices as a result people will be forcing the government to take the easy way out by making no change. Creating more coal based plants we affect the planet by warming it up faster than looking for better environmental options. Another Lucy states will be change in landscape because rising temperatures and pattern changes of weather, as some wildlife will be forced to move where it’s colder leaving others without any viable habitat putting our wildlife at risk. However, this...

...improper planning schemes wind farms are being placed in migratory paths for birds and bats killing or injuring them, attract and kill pollinator insects, and (according to some) decrease the aesthetic beauty of the landscape. The first wind farm in the United States was in Crocheted Mountains, New Hampshire in 1980. Since then they have grown to 119 wind farms in the United States. There are two basic forms of wind turbines, vertical axis and horizontal axis wind turbines. The vertical axis turbine blades have several designs but the commonality between the designs is that they have open spaces some people refer to as lattice spaced openings. Horizontal axis turbine blades look like propellers on an airplane. It is estimated that roughly 573,000 birds are injured or killed annually, roughly 600,000 bats are injured or killed annually and innumerable pollinator insects are killed annually by wind farms. The problem with vertical axis turbines is that the spaces in the blades are wonderful perching and nest building sites for birds when they aren’t moving. So when the blades start to move the birds are injured and the nest and eggs are destroyed. The problem with horizontal axis turbines is that they can run at high speeds so birds are unable to escape the current or are hit while trying to feed on dead or injured birds or insects. Researchers have discovered that simply changing the...

...climate change has on nature can be catastrophic. Climate change has already had a noticeable effect across the globe and on the environment. Glaciers are shrinking, ice along rivers and lakes are melting earlier, plants and animals have shifted their ranges, trees are flowering sooner, and sea levels are rising. These effects were predicted in the past by scientists, and they are finally occurring. Most of climate change is caused by global warming and the greenhouse effect. (Gardiner, 2004) Global warming is a rise in the average temperature on the earth’s surface. Scientists who study the climate have evaluated climate patterns since the early 1800’s. From their evaluations, they have noticed a rise in temperature, from about 0.7 to 1.4 degrees Fahrenheit and they estimate temperatures to continue to rise over the next century, an additional 2.5 to 10.4 degrees Fahrenheit. With this change, scientists fear that all living organisms will have a hard time adapting to these rapid climate changes (Mastrandrea & Schneider, 2005) To understand global warming and climate change, it has to be understood what causes it. Human activities play a crucial role in harming the...

...PEST CONTROL Pest control is as a minimum as vintage as agriculture, as there has continually been a need to keep crops loose from pests. So one can maximize meals production, it is effective to protect plants from competing species of flowers, in addition to from herbivores competing with humans. Pest manage Pests are organisms that lessen the first-rate or yield of a crop or plant (Biology AS textbook, Indge, Rowland, Baker). Pest manage uses various strategies to cast off populations of specific pests to boom productiveness of plants. The two maximum not unusual techniques are the use of insecticides and organic Pest manage. This essay will display how and why biological Pest control is favored over using insecticides. organic Pest manage is using a mainly chosen organism to devour, kill, or otherwise harm a selected pest, and frequently referred to as 'natural enemies' in line with the object organic control of Pest Insecticides are used international to manipulate agricultural pests. They kill and repel unwanted pests, but also cause many human deaths each yr. This lesson explores the huge use of pesticides in agriculture and compares the advantages and issues related to those beneficial but dangerous chemical compounds. What do you suspect is the primary aim of agriculture? Agriculture became advanced to provide crops and farm animals for human intake. Because the human population increases, the amount of food produced could be very critical. Sadly, there are different...

...engineering has been gradually improved, and the bioengineer could make a huge difference in our life by modifying the crops that we need. Genetically modified food could solve many problems to humans such as, cultivating new crops with new characteristics that could help humans. Also genetic engineering could help some countries to cultivate new crops they couldn’t cultivate it before for many reasons such as weather, soil type, and cultivating seasons. However, recently genetically modified food could make a big influence to human’s life, and it helped them to cultivate new crops, they wouldn’t be able to cultivate it without it. About 200 years ago Thomas Malthus predicted that according to that big increase in the humans’ population which is currently up to six billions, “the number of mouths that need to feed is increased. The numbers of cultivated crops is stable since Thomas Malthus has made his prediction; this has been the result of amazing technological advances in agricultural sciences with advent of biotechnology and genetic engineering, which have served to increase the average yield of various farm products’’ (Nayak et.al 112). Most of the countries started to cultivate genetically modified crops to feed their needs, and they could increase their crops number quickly. Global cultivation of genetically modified food in 1996 was three million hectares, and that was by the efforts of farmers in six countries only. In 2008 the farmers in 25 countries could cultivate...

...well. Some believe that household appliances contribute to the warming also. Global warming is dangerous because it affects the environment, and that can cause many problems and dangerous things to happen. It can causer floods in certain places, causing greenhouse gases to be released into the earth’s atmosphere causing the earth’s temperature to rise. Cutting down trees, smoke from factories, exhaust system from cars, trucks, and motorcycles all contribute greenhouse gases being released causing global warming. Some scientists even believe that the human population is also a factor when it comes to global warming. The main reason why global warming is happening is because of the burning of fossil fuels and deforestation, caused by human activity. We should plant more trees instead of cut down more trees. To prevent global warming policies should be in place and we need to take certain steps to prevent it from happening. Global warming is caused when the heat from the sun and greenhouse gases are released into the earth’s atmosphere, causing global warming and a need to come up with a solution to prevent global warming and the destruction of the earth’s atmosphere and all that inhabits the earth. Human activity is not the only reason global warming is happening. Global warming was occurring long before human activity. According to scientists, ninety percent of global warming is caused by humans. The climate warming is much faster than the climate...

...government is still allowing the United Stated to continue with GMO cropping and without labeling it. We should know why it is harmful to our health and how we can prevent it. GMOs could cause health issues, create allergies, toxins, new diseases and nutritional problems. First, GMOs are harmful to our health. Second, these crops can lead to contaminated organic crops, and serious destruction of the environment, which could also lead to toxins and allergens surrounding us. Third, there are some companies that intend to monopolize market-foods, which work with GMOs. Finally, labeling should be a very important factor in the GMO industry, to ensure people would recognize how dangerous GMO’s are for us. GMOs are special organisms in which the genetic material has been altered for improvement productivity and product quality. First, Research and studies show that GMOs could be very harmful. Through manipulating our crops our health is at a serious risk. “Numerous health problems increased after GMOs were introduced in 1996. The percentage of Americans with three or more chronic illnesses jumped from 7% to 13% in just 9 years; food allergies skyrocketed, and disorders such as autism, reproductive disorders, digestive problems, and others are on the rise.” (The Institute for Responsible Technology 2006-2013) Unfortunately, with today’s fast paced society more families are on the go.

...Jayadev Kakumanu 8/10/2013 EN 1420 Global warming is caused by carbon dioxide emissions from fossil fuel burning power plants, carbon dioxide emissions from burning gasoline for transportation, methane emissions from animals, agriculture such as rice paddies and from arctic sea beds. It is also caused by deforestation of tropical rain forests, and increase in usage of chemical fertilizers on croplands. This paper will examine the advantages and disadvantages of global warming as well as the preventative measures our society can take to stop the progress of global warming. And finally, decide whether global warming is a lie or a hoax. There are many disadvantages to global warming. Global warming spreads diseases, as northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. Global warming also causes warmer waters, which means more hurricanes. Some areas of our planet will suffer serious droughts and heat waves. Africa will be hit the most with more severe droughts expected in Europe. There are also going to be economic consequences, hurricanes can cause billions of dollars in damage and diseases cost money to treat. Polar ice caps will melt. This melting of ice caps will raise sea levels. The melting will also throw the ecosystem out of balance. The ice caps are fresh water so when they melt they will make the ocean less salty. The rising temperatures will endanger the survival of several species. The ice caps are white...

...Global Warming Global Warming is a very important ecological issue, and it has many negative effects on our environment. Global warming is also known as the greenhouse effects. Scientists have been aware of the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be much colder if it had no atmosphere. The greenhouse effect is the absorption of energy radiated from the earth's surface by carbon dioxide and other gases in the atmosphere causing the atmosphere to become warmer. Global warming has affects on the entire ecosystems and climates. It has been a big issue that has affected the environment, people, and even the whole world. If Global Warming is not stopped now the results could be catastrophic. Global warming is increasing the frequency and intensity of tropical storms all over the world. People believe in these statements, but there are many people around the world who refuse to believe that human contributions are the main causes of global warming. Many believe that the increase is part of the natural climatic change of earth. Global warming includes the natural climatic change, and the grounds of human causes. Because of those wrong attitudes and lifestyles of human, the problem which are caused by global warming are more serious. There are changes in weather patterns causing more hurricanes, tsunamis, floods, and other types of storms within the past few years, and these changes definitely affect human health.

...Genetically Modified Foods Linda L. Day SCI207 – Dependence of Man on the Environment Cynthia Collins February 26th, 2012 Genetically Modified Foods Genetically modified foods have increased the total harvest of many cash crops by eradicating the harm done by weeds and insects, and for the most part, this has been the single greatest benefit that GMOs have presented within the last decade. There are benefits being speculated and tested as of now to future speculation on what this science can bring us. There are other ways that GMOs are able to increase the overall bounty of a crops harvest, such as resisting dangerous diseases and being able to sustain the plant with less water or less nutrients. There have also been attempts to create plants resistant to more untamable forces of nature rather than pests, such as the temperature. There have been many speculations that cold-resistant crops, mainly corn and other fruits and vegetable, could be created by taking the DNA of cold-tolerant fish in the Arctic and splicing it with these foods. “An antifreeze gene from cold water fish has been introduced into plants such as tobacco and potato. With this antifreeze gene, these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings,” (Whitman). One benefit in particular that has seemed to have caught the eye of retailers especially adding more nutritional benefits to foods, such as rice with built-in Vitamin A that can help prevent blindness...

...well as other countries, has a great deal of support from the government for commodity crop such as “wheat, corn, and soy production this also goes through the use of government subsidies. The government support for commodity crop has successfully made farmers ignore, more healthy crops; furthermore, a great deal of industrial crops grown here in the United States are being used for animal feed in “concentrated animal feeding operations ( CAFOs), also better known as factory farms.” With the support of the government the industrial crop production has increase in corn, as well as soy-fed animals, this also increased production for foods that use corn that is high fructose corn syrup; this ultimately contributing to the commonness of health problems for instance, heart disease, obesity as well as type 2 diabetes. This connection between food and our health is indisputable. While relationships are hard and very confusing, but the continuous stream of scientific research the media exposure for food and nutrition- has one thing to be sure of: and that is choosing sustainable food is a no “brainer” to attaining optimal health. “Sustainable crops are grown in...
