What Parts Of A Shark's Anatomy Are Considered Useful To Humans?

While humans considered sharks to be cold blooded killers stalking humans, reality is quite different. In fact, while we consider human fatalities that resulted from shark attacks, the real victims here are in fact, sharks.

You see, while there are about 63 shark attack worldwide, every year, 100s of millions of sharks are killed during that same period of time. In fact, contrary to humans who are mostly victims of confusion, humans are actually stalking and killing sharks on purpose.

You see, there are several ways that people use the sharks anatomy to benefit the well-being of humans. As an example, osteoarthritis research Omega 3 shark liver oil which is seen as a good source of that supplement is also used to treat arthritis related conditions and so is shark cartilage.

Shark cartilage is also used to make cartilage pills which some believe are able to cure cancer although scientists are skeptical.

Shark meat is also considered a delicacy which is mainly used Asian recipes, especially in shark fin soup. Unfortunately, many sharks are butchered by fishermen practicing finning and releasing them into the wild, guaranteeing them a slow, painfully cruel death sentence.

It is always sad to see curious and gentle giants such as the basking shark being butchered in certain parts of the world where no laws are protecting them. You see, because of their size, they provide 1 ton of meat, 400 L of oil and a large vitamin-rich liver which represents 20% of that shark species total weight.

In some cases, shark liver oil will also be used by fishermen to keep seabirds, dolphins and sharks far away from their net to prevent damages and loss of fish.

There is also the fact that the carcasses of dead sharks are also used to create some shark repellent. It is then commercialized and chemically imitated to diminish the costs while keeping its efficiency.

As you can see, they are helping a lot more than they hurt us. Why not see these poor animals as deserving of our respect in their own territory. After all, would we be as friendly if confronted by intruders in your own house?

My name is Sylvie Leochko. I always have been intrigued by sharks. Although they tend to bring up a fear in most people, It is sad to see how exploited they are, sometimes in the cruelest manner.

Why Is Nanotechnology Important?

First, you need to know what the term means...I will reference Wikipedia for a proper definition.

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices with critical dimensions that lie within that size range.

It is simply technology of the smallest kind. Why is that important? The laws of physics as most of you know them don't function in quite the same way when you talk about things this small. But you may be surprised to know that this is not "new" technology.

The first use of the concepts in 'nano-technology' (but predating use of that name) was in "There's Plenty of Room at the Bottom," a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959. Feynman described a process by which the ability to manipulate individual atoms and molecules might be developed, using one set of precise tools to build and operate another proportionally smaller set, so on down to the needed scale. In the course of this, he noted, scaling issues would arise from the changing magnitude of various physical phenomena: gravity would become less important, surface tension and Van der Waals attraction would become more important, etc.

This technology is making leaps and bounds. Quantum physics, quantum mechanics, nanotechnology, all of these are related terms. You could ride an elevator into space because of nanotubes. Nanofiltration will bring water to rural areas who otherwise could not properly filter drinking water. There are ideas in the works that would allow nanomachines to deliver medicine directly to specific types of cells in the body. For example, an injection of nanobots with a chemotherapy drug for cancer could deliver the dose directly to the cancer tissue, reducing the damage to other tissues, and the quantity of medicine needed for treatment. There are nano materials that you can wear just like your shirt, that can change instantaneously into bullet and pierce proof material. There are literally thousands of other applications out there, but what is important for you to know is that this is a legitimate, and worthwhile thing to study.

These ideas are no longer science fiction, they are real.
