Environmental Activism $115 Designer Cosmetic Collection From Cosmetique -- Only $1! Environmental Activism 1. The large mainstream environmentalism groups started to compromise too much with regulatory agencies and bureaus, starting with the Glen Canyon Dam project. This began an estrangement with the mainstreams that culminated in the rise of more militant groups like Earth First! Glen Canyon represented what was fundamentally wrong with the country's conservation policies: arrogant government officials motivated by a quasireligious zeal to industrialize the natural world, and a diffident bureaucratic leadership in the mainstream environmental organizations that more or less willingly collaborated in this process. The mainstream environmental groups and government held the premise that mankind should control and manage the natural world. The radicals held that our technological culture with its intrusions on natural world had to be curtailed, perhaps even undone, to keep the ecology of this planet and our role in it viable. It marked a shift from a rearguard strategy (mainstream) to protect wilderness to an affirmative attempt to roll back the artifacts of civilization, to restore the world to the point where natural processes such as the flow of rivers could continue. The mainstream environmental movement is now perceived by many as out of touch with people's deep concern about environmental degradation, has become systematized. The activists use approaches such as industrial vandalism or "ecotage" to foster dramatic results. Some other methods employed are tree spiking, tree sitting, road blockading, demonstrations, tree pinning, ship sinking, dam breaking and outright terrorist-type sabotage (bombing power stations, bridges, power line, etc.) There may be some complimentary results of the efforts of both mainstream and radical groups. The large environmental organizations, while denouncing the radical's confrontational activities, have then been able to use their ample finances to take the campaign to Congress or the courts with the impetus of public support the radicals generated. 2. With Soule's quote, including "Vertebrate evolution may be at an end" it means that the civilization complex has lost its reference point by overwhelming the natural processes it has always used to define itself. The otherness of nature is disappearing into the artificial world of technology. As the environmental crisis worsens, we can expect increased attention directed at the ecological sciences, resource management, pollution control, and technological supervision of the reproduction of valued species, including man. Toynbee writes that the ecological scarcity of the future will be so severe that the "within each of the beleaguered'developed' countries there will be a bitter struggle for control of their diminished resources". This conflict will inevitably lead to the imposition of authoritarian regimes. There is already evidence of "ecological elite's" where power and status are increasingly measured not merely by economic control, but by control over the ecology. Access to clean water, fresh air, open wild spaces, and natural products is competing with ownership of German autos and Swiss watches. It is becoming the main preoccupation of political debate. As an example, even when a corporation decides to create a item through genetic or non-genetic engineering, it is often indirectly determining what species will be exterminated to increase profits, which habitats will be sacrificed for economic growth, and whose children will be allocated the toxic water, poisoned food, and radioactive living space. If the environmental crisis is causing us to reexamine and reject the accepted values of the civilization complex in its entirety, a unique event is taking place: the passing of civilization into history. 2. Societal breakdown in the face of a continually deteriorating physical world may face many problems. As stated above by historian Toynbee, a conflict may lead to the imposition of authoritarian regimes. Political scientist Ophuls offers a similar view, that "in the light of ecological scarcity... the individualistic basis of society, the concept of inalienable rights, the purely self-defined pursuit of happiness, liberty as maximum freedom of action, and laissez-faire itself all require abandonment if we wish to avoid inexorable environmental degradation and perhaps extinction as a civilization". Economist Heilbroner see this process of environmental disarray as transcending political distinctions between capitalist and socialist countries, irregardless of the conservative thinking that "democratic" capitalism has triumphed over communism. He believes that the urgencies of the future "point to the conclusion that only an authoritarian, or possible only a revolutionary,! regime will be capable of mounting the immense task of social reorganization needed to escape catastrophe". The story of the IK tribe and its analogy to the future of the western society in the face of continuing biological meltdown may prove true. We have had various authorities from a variety of disciplines reach similar conclusions about this unproecedented problem, it suggests, at the very least, that the environmental crisis has made our

Pectinase and Protease essays

Pectinase and Protease essays NOTE:Just so you know, I received full 100% on this paper. By the way, I am doing the I.B. An enzyme is simply a protein which acts as a catalyst in biochemical reactions. Each enzyme is specific to a particular reaction or group of reactions. Since enzymes act as catalysts, they are considered to be tremendously precious to industrial biotechnology. Attempts to use enzymes in the manufacturing field have been recorded as far back as the late 1800s. Since then, weve come a long way. Now a days, enzymes are commonly used by industries to process starch, brew and make cheese. There are two enzymes, which are exceedingly important in the biotechnology industry, they are pectinase and protease. Pectinases are actually a mixture of enzymes, which, along with others such as cellulase, are widely used in the fruit juice industry where they are widely used to help extract, clarify and modify fruit juice. Pectins are large polysaccharide molecules, made up mainly of chains of several hundred galacturonic acid residues. Enzymes in this pectinase group include polygalacturonases, pectin methyl esterase and pectin lyases. These pectinase enzymes act in different ways on the pectins, which are found in the primary cell walls and in the middle lamella. Pectins are well known for their ability to form gels. Pectinases are produced during the natural ripening process of some fruits, where together with cellulases, they help to soften their cell walls. These enzymes are also secreted by plant pathogens such as the fungus Monilinia fructigena and the soft-rot bacterium Erwinia carotovora, as part of their strategy for penetrating the plant host cell walls. In fact, the products of such enzyme assaults act as a signal which induces uninfected cells to defend themselves. Protease refer to a group of enzymes whose function it is to break down proteins and are also referred to as proteolytic enzymes or proteinases. T ...
