    Ll Bean Environmental Analysis

    Environmental scanning is the act of collecting external marketing information. This information is then interpreted to find potential trends, and identify future market opportunities or threats. The types of environments analyzed are competitive, political-legal, economic, technological, social, and demographic. I have chosen to focus on the company L.L. Bean, and the social and competitive environments. I have chosen this company because I am a very big fan of their products, and I chose these environments because I think L.L.

    Synthetic Pesticides In King Corn

    Amanda, I most definitely agree, our fruits and vegetable crops must grow without the synthetic pesticides. We all believe that organic is always the best choice because it is better for our health, the importance of our environment, and the people who grow our food. I read that the hazard risk from pesticides on the traditional or regular food of produce fluctuates from very low to very high depending on the type of produce and what country where it’s grown. Learning from our assignments about ecology and how necessary it is to understand how living things interact with each other as well as with nonliving elements gave me a better perspective and understanding life purpose. Watching the movie “King Corn,” gave me a better view about the synthetic…

    The Dangers Of Pesticides In Imperial Valley

    Did you know that Calexico is consider one of the worst cities for families? Around the Imperial Valley, we can see various agricultural fields. These agricultural fields are around our homes, parks and schools. Pesticides are sprayed on these agricultural fields to kill weeds, fungus, insects, etc. Pesticides are not only sprayed in our fields, but families are also using them in their homes or in the workplace. However, I feel that they are harming our children and families. Pesticides can cause various health hazards such as headaches, nausea, and skin and eye irritation to acute dangers such as cancer. Driving to the mall or near schools, we can see how they are using a crop duster and pesticides are sprayed, and how easily it can be blown…

    Pesticide Penetration

    Pesticide Penetration

    The state of the chemical, i.e., solid, liquid, or gas, affects the chances of pesticide penetration into the body. Liquids or gasses can get into the body through all three routes, whereas solids tend to have a lower chance of entry through the lungs. However, if solid particles are small enough or if they remain on the skin long enough, penetration into the body can take place in the same ways to those of liquids or gasses. The most common route by which pesticide users are poisoned is absorption through the skin. Dermal absorption may occur as a result of splashes and spills when mixing, loading or disposing of pesticides. To a minor degree, it may result from exposure to large amounts of residue. The degree of hazard by dermal absorption…

    Water and Quality Contamination

    Water and Quality Contamination

    Background: According to the Millennium Development Goals Report 2012, 783 million people, or 11 per cent of the global population, remain without access to an improved source of drinking water. Also the United Nations has long been addressing the global crisis caused by insufficient water supply to satisfy basic human needs and growing demands on the world’s water resources to meet human, commercial and agricultural needs (un.org). In this experiment water quality and contamination of groundwater was investigated. First, I observed the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the large amount of contamination in the water, while the laundry detergent will just create an aroma smell to it. Considering the smells and color to these ingredients I think that it will cause the water quality to have a bad smell and cause the water to be very cloudy. Once filtering the contaminated water, the water will be clear and purified. Second, I will experiment water treatment and filtering. I predict that once the contaminated water is treated and filtered that it will leave me with less contamination or none at all. Then for the last experiment, I will determine the difference between bottled water and tap water to discover any contamination. I predict that the tap water will be the most contaminated and with the most chemicals in it, while the bottled waters; Dasani and Fiji will be completely filtered and free of any chemicals.…

    Pesticides In Silent Spring

    Busy people trying to get from one place to another not realizing the beauty of our planet just don’t take the extra steps to take care of it. Departments of public works and landscapers build beautiful gardens and work to grow grass in areas, not for it to be ruined by mass pollution. The use of pesticide can be helpful, however taking a toll on our health. The Toxics Action Center (2015), pesticides are used almost everywhere— not only in agriculture fields, but also in buildings, forests, roads, homes, parks and schools. Each different pesticide serve a different purpose, for example, herbicides are used to kill weed & plants, insecticides are used to kill insects, fungicides, are used to killed fungus, rodenticides are used to kill rodents. Not realizing the harmful effects, pesticides can be found in our air, water and food. Throughout the book “Silent Spring,” we…

    The Harmful Effects of GMO's

    Genetic Engineering has been around since the 1970’s, but the process has become more complicated and ambiguous over time. A genetically modified organism, or GMO, is a plant, animal, or microorganism that has been produced to overcome any natural restrictions (Happiness). It encompasses eradicating the DNA, manipulating it, and then reinserting it into the original or alternative organism (Executive). Although GMO’s have some benefits, their harmful effects are far more extensive.…
