Which Are More Eco-Friendly, Real or Synthetic Sponges

While it is true that real sea sponges have been in use since the Roman Empire, synthetic alternatives made primarily from wood pulp became commonplace by the middle of the 20th century when DuPont perfected the process of manufacturing them. Today, most of the sponges we use are made from a combination of wood pulp (cellulose), sodium sulfate crystals, hemp fibers, and chemical softeners. Artificial Alternatives to Sea Sponges Although some forest advocates decry the use of wood pulp for producing sponges, claiming that the process encourages logging, the manufacture of cellulose-based sponges is a pretty clean affair. No harmful by-products result and there is little waste, as trimmings are ground up and recycled back into the mix. Another common type of artificial sponge is made of polyurethane foam. These sponges excel at cleaning, but are less ideal from an environmental perspective, as the manufacturing process relies on ozone-depleting hydrocarbons (set to be phased out by 2030) to blow the foam into shape. Also, polyurethane can emit formaldehyde and other irritants and can form cancer-causing dioxins when incinerated. Commercial Value of Real Sea Sponges Some real sea sponges are still sold today, used for everything from cleaning car and boat exteriors to removing make-up and exfoliating the skin. The product of at least 700 million years of evolution, sea sponges are among the world’s simplest living organisms. They survive by filtering microscopic plants and oxygen from the water, growing slowly over many decades. Commercially, they are prized for their natural softness and resistance to tearing, and their ability to absorb and discharge large amounts of water. Scientists know of more than 5,000 different species, though we only harvest a handful of them, such as the exfoliating Honeycomb (Hippospongia communis) and the silky smooth Fina (Spongia officinalis). Sea Sponges in the Ecosystem Environmentalists are concerned about protecting sea sponges, especially because we still know so little about them, particularly with regard to their potential medicinal usefulness and their role in the food chain. For example, researchers are optimistic that chemicals emitted from some living sea sponges could be synthesized to create new arthritis treatments and possibly even cancer fighters. And sea sponges serve as the primary food source for endangered hawksbill sea turtles. Shrinking amounts of natural sponge could push the prehistoric creature over the brink to extinction. Threats to Sea Sponges According to the Australian Marine Conservation Society, sea sponges are under threat not only from over-harvesting but also from sewage discharge and stormwater run-off, as well as from scallop dredging activity. Global warming, which has been increasing water temperatures and altering the ocean food chain and seafloor environment accordingly, is also now a factor. The organization reports that very few sponge gardens are protected, and is advocating for the creation of marine protected areas and more sensitive fishing methods in regions where sea sponges remain abundant.

Comparing Machiavelli And Hobbes Political Writings And...

Both Machiavelli and Hobbes have personal roots in violent historical times which are seen reflected in their respective theories about the use of violence in politics. The legitimate use of violence is a topic addressed by both theorists in their respective works, as read in Selected Political Writings and The Leviathan. Who has the monopoly over the use of violence, what its terms of use are, and what the consequences of its use are, are distinct from the works of both Machiavelli and Hobbes. Hobbes’ believed that the world, as well as humanity, was mechanic and operated according to physical laws and chains of cause and effect. He claimed fear was the determining factor in men’s lives, which would cause them to give their liberty over to a sovereign, which would act as man, operating according to the same laws of cause and effect as the rest of the world. This sovereign alone, as the sole political authority, held the legitimate use of violence. As an exception to this, another legitimate use of violence was in a member of the commonwealth’s own self-defence, â€Å"...because no man is supposed at the making of a Commonwealth, to have abandoned the defense of his life, or limbes, where the law cannot arrive time enough to his assistance.† In this way, the Sovereign defends his own power over the commonwealth by granting man legitimacy of violence for the sake of his own safety, thus further removing fear within the commonwealth, and ensuring t heir continued allegiance to theShow MoreRelatedThe Influences of Selected Political Writings by Machiavelli and Leviathan by Hobbes1717 Words   |  7 Pagesto an ideal will soon discover he has been taught how to destroy himself, not preserve himself. -Niccolo Machiavelli Every person has a chance to leave a mark on this earth, and every person gets to decide how he or she will do that.
