...Have you ever looked in an aquarium and seen a bright green plant that made the aquarium look very pretty? Don’t let this plants pretty color fool you; it is an invasive species in the wrong habitat. An invasive species is essentially an invasion altogether. In terms of ecology an invasive species is when either a plant or animal is introduced to a different area from their natural habitat and cause environmental or economical harm. Giving this definition I will discuss Caulerpa Taxifolia. Caulerpa Taxifolia is a macro algae invader that is a multicellular plant native to warm saltwater. It is one of the most invasive green alga in the seas. It is considered invasive because it has the ability to spread over large areas in the ocean while forming dense mats, causing ecological and economic issues such destroying sea weed, sea grasses, fishes, commercial fishing, boating. Caulerpa is a salt-water plant with structures that look jut like roots, stems and leaves. The roots of Caulerpa are called rhizoids, which grow into the ocean floor to absorb water and nutrients. Caulerpa have leaf like structures that stick up called fronds, which are a bright green color and are photosynthetic. The stems of Caulerpa are called stolon, which grow above the ocean floor; the stolon when fragmented grows a new Caulerpa plant. Its normal habitat is in tropical waters around the world such as the Indian Ocean. Caulerpa taxifolia is not invasive in its native habitat and reproduces sexually. Grazing...

...Green Technologies Green technology, also known as environmental or clean technology, minimizes impacts on the environment and natural resources. It’s based on concepts such as conserving water and energy, reducing waste and pollution, harnessing renewable energy sources, finding ways to reuse materials, and developing less polluting technologies. Green technology is everywhere these days; in the news, politics, fashion, and of course technology. Green Technology is becoming so widespread throughout the world. People are becoming more energy efficient in their homes by buying water-efficient showerheads that are low-flow models, adjusting their refrigerator and freezer temperatures, buying compact fluorescent light bulbs, buying energy efficient appliances, and by recycling rechargeable devices like cell phones or digital cameras. As awareness grows about environmental issues such as pollution, human impact on climate change, and depletion of natural resources, so is interest growing in environmentally friendly products and services. For example, the popularity of green cleaning products has increased in recent years. Nontoxic, biodegradable cleaning products are safer for use in the home meaning they are less likely to cause health problems. They also keep harmful chemicals out of the environment. Compact fluorescent light bulbs (CFLs) are another popular eco-friendly product; compared to traditional, incandescent light bulbs, CFLs use way less electricity. ...

...believe that bio-fuel production causes more problems than it solves. Describe the main reasoning behind this view. · Bio-fuel production causes loss of tropical forest and other natural habitats, depletes oil, accelerates climate change, and exacerbates world hunger. · To grow biofuel crops, there needs to be cutting and burning of forests · You need burning of oil based fuel and use of petroleum based fertilizers to grow biofuel crops which leads to less oil which leads to a new for more biofuel so you burn all the forests and you need the oil to regrow them again · Deforestation – especially in South America and Indonesia accounts for 20% of all carbon emissions · Farming biofuels produces nitrous oxide which is bad for climate change · Large scale burning and cutting to grow crops –including biofuel crops- also causes adjacent forest decline: it causes reduced transpiration and hence reduced rainfall in adjacent forest areas result in drought cycle which accelerated death of trees which further reduces transpiration and rainfall. The accelerated death of trees results in warming of forest floor and accelerated decomposition of soil organic matter and explosion of termite population son dead tree trunks and branches. Both of this releases huge quantities of methane and carbon dioxide · The use of biodiesel from algae is not as green as it seems. It can generate four times the greenhouse emissions from regular diesel. When algae is farmed...

...Discussion Question: 1. What degree of confidence do you have that Gerritsen, Buck, and Leay will be able to execute their three-point plan? What factors have to come together for the plan to work? What advantages does Aquaflow have in its efforts to execute the plan and continue to grow? Answer: They can truly execute the three-point plan because it can be one of the most competitive player in the market. Some factors to consider to make this plan work is that Aquaflow must use wild algae to help clean up water. They should also try to cultivate mono-cultures or a small number of species although its quit expensive, hard to scale and has significant technical risk. Aquaflow must look to partner in where the ‘fuel’ is a byproduct of the scheme’s overall value and etc. Aquaflow believes it now has a world-leading multi-biomass to biofuels capability and technology offering. This is a robust and highly integrated technology package which can leapfrog other biomass to biofuel technologies because it goes straight to blended fuel stock and avoids intermediate pathways. 2. To what extent did passion play role in the founding of Aquaflow and its early success? Do you think that someone without passion for alternative fuels could have successfully founded the firms? Why or why not? Answer: They show that they are truly dedicated to their work and face all the challenges and risk that will happen. They improved the Aquaflow a lot and make used of their intelligence to build...

...Biofuels. Name: Institution: Course: Tutor: Date: A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass, solid biomass, liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye, D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products or from living organisms. Examples of biofuels include; bioethanol which is an alcohol made from fermentation process. Another example of biofuels is biodiesel which is made from vegetable oils as well as animal fats. Biofuels have got several ways in which they are made. Therefore in this essay I am going to analyze few methods. Biofuels are made from materials known as feedstock. This comprises mostly of crops or products mainly waste vegetable oil. (Mitchell, D. 2010). These materials are converted to biofuels or bioenergy. These feedstocks have got merits and demerits depending on what percentage of biofuel can be gotten from them. Feedstocks can further be classified as first and second generation. The former refers to those which are widely grown by people and at the same time used for some other purposes. They are mostly used for food and feed production. (Lane, J. 2010). Hence, they serve the purpose of being used as food as well as to produce biofuels. The examples of first...

...What is Microbiology? Microbiology is the study of organisms too small to be seen with the naked eye. Originally, emphasis was placed on harmful micro organisms which cause disease or spoilage of beverages and food, but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur, such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS, which capture public attention. Control and eradication of infectious diseases remain important goals of many microbiologists. The recognition that microorganisms were responsible for what was earlier thought to be "spontaneous generation" opened the door to industrial (pharmaceutical, chemical, energy) and food microbiology, technologies which contribute substantially to today's way of life. Microorganisms in soil and water are essential in the transformation of carbon, nitrogen, oxygen, sulfur and iron to products needed by plants and animals. In various ways, microbes participate in environmental cycling and degradation and global change. In the last few decades, microorganisms have been recognized as ideal model systems for the study of basic biological processes. More recently, microbiologists have brought an exciting dimension to the study of biology...

The resources that we have used up from the environment have often been nonrenewable and in our heedless march to glorious comfort, we have ignored the consequences of the effect that we are having on the world we live in. With the results of our negative impact on nature coming around to haunt us, there have been a rising global awareness and movement to better ourselves. Green technology is a major part of it. Green technology is the application of the environmental science to conserve the natural environment and resources, and to curb the negative impacts of human involvement. The main idea behind green technology is to provide sustainable growth. That is, using resources from the Earth in a renewable fashion. The following report outlines some aspects of green technology and discusses three main ideas: Solar energy, Green Buildings, Biofuels. In the report, it has been discussed how each of these technologies...
