With regard to the reasons for the extinction of dinosaurs, it is still constantly being studied. For a long time, the most authoritative view is that the extinction of dinosaurs, and 6500 million years ago a large meteorite related. According to the research, when there was a 7-10 km in diameter asteroid crashed into the Earth's surface, causing a big explosion, a large amount of dust thrown, such as the atmosphere, forming clouds of dust cloud, resulting in a temporary cessation of photosynthesis of plants, Therefore, the extinction of the dinosaurs.
Asteroid collision theory, and soon gained the support of many scientists. In 1991, in Mexico's Yucatan peninsula, long period of time found a place in the meteorite impact craters, a fact further confirmed this view. Today, this view seems to have become dogma.
But there are also many people of such an asteroid impact theory of skepticism because the facts are: frogs, crocodiles and many other pairs of temperature-sensitive animals withstood the Cretaceous and survived. This theory can not explain why only the dinosaurs die off. To date, scientists have made assumptions about the causes of extinction of the dinosaurs have been no less than a dozen relatively rich in provocative and dramatic "meteorite collision said," is just one of them only.
Addition to the "meteorite collision that" outside the main points of view on the extinction of the dinosaurs are the following:
First, climate change, said. 6500 million years ago, the Earth's climate suddenly changed, the temperature dropped sharply, resulting in decline in atmospheric oxygen, so that the dinosaurs could not survive. Some people think that dinosaurs were cold-blooded, but with no hair or a warm organ, unable to adapt to the decline in the Earth's temperature, were frozen to death.
2, species struggles. The late dinosaurs, small mammals first appeared, these animals are rodents and carnivores, may dinosaur eggs for food. Because of this lack of natural predators of small animals, more and more and eventually finished the dinosaur eggs.
3, continental drift, said. Geological studies have shown that, in the era of the dinosaurs to survive there is only one continent on Earth, namely, "Pangea." As the earth's crust changes, the continent took place in the Jurassic larger division and drift, culminating in the environment and climate change, dinosaurs be extinct.
Fourth, changes in geomagnetic said. Modern biology has proved that certain biological death and magnetic field. More sensitive to magnetic fields of biological, in the Earth's magnetic field changes, it also could lead to extinction. It seems therefore that the extinction of dinosaurs may be related to changes in the Earth's magnetic field.
5, angiosperms poisoning said. The late dinosaurs on Earth the gradual disappearance of gymnosperm, replaced by a large number of angiosperms, gymnosperms, these plants contain toxins that are not, a huge dinosaur body appetite odd large, a large number of intake of angiosperms led to accumulation of toxins from the body too more than was finally poisoned.
6, acid rain, said. The late Cretaceous period may be too strong under the acid rain, the soil, including trace elements including strontium be dissolved, dinosaurs through drinking water and food intake directly or indirectly, strontium, acute or chronic poisoning, the last batch after batch died.
With regard to the causes of dinosaur extinction hypothesis, far more than the above-mentioned these types. However, these types of the above-mentioned hypothesis, in the scientific community has more supporters. Of course, each of the above is a saying there imperfections. For example, the "Climate Change said," does not clarify the causes of climate change. After inspection, some small dinosaurs Coelurus enough with the early phase of small mammals to compete, so "the struggle of species that" there are loopholes. In modern geology, the term "continental drift theory" itself is still a hypothesis. "Angiosperm poisoning said," and "acid rain, said" The same lack of sufficient evidence. Therefore, the real reason for dinosaur extinction,
Remain to be further explored.

A, climate change. 65 million years ago, the earth's climate change, temperature sudden drop sharply, atmospheric oxygen levels drop, make the dinosaur cannot survive. There are also people who believe that dinosaurs are cold-blooded, no hair or heat preservation organ, cannot adapt to the earth, have been frozen.
Second, the species struggle. In the end, the first dinosaur small mammals, these animals of rodents predators, may to feed dinosaur egg. Due to the lack of small animals, more and more natural, finally ate the dinosaur egg.
Third, continental drift. Geology research proves, in the time of the dinosaurs of the mainland, namely "only a generic ancient land." Due to the changes in the continental crust, of the Jurassic and drift phenomena split larger, eventually leading to environment and climate change, the dinosaurs and extinction.
Four, geomagnetic change said. Modern biology, some biological magnetic field of death and relevant. The biological magnetic field is more sensitive to changes in the earth's magnetic field, may cause extinction. By inference, the extinction of the dinosaurs may change with the magnetic field of the earth.
Five, the angiosperms poisoning. In the end, the dinosaurs on earth gymnosperms disappearing, replaced by a large number of angiosperms, these plants containing gymnosperms have no toxin, form a huge dinosaur food intake, thrashing angiosperm cause body endotoxin accumulation overmuch, finally was poisoned.
Six, acid rain. Late cretaceous may have strong acid rain, soil microelement, including strontium being dissolved by water and food, the dinosaurs, directly or indirectly, strontium intake of acute or chronic poisoning, the last batch died.
The reasons about the extinction of the dinosaurs, far above the hypothesis. But above all, scientists in several hypothesis has more supporters. Of course, there is every imperfect places. For example, "the climate change said." not illustrate reasons of climate change. Some of the investigation, the small dinosaur bone dragons and virtual as small early mammals, therefore "rival struggle" also exist species loopholes. But in the modern geology, the theory of continental drift ", "itself is still a hypothesis. "The angiosperms poisoning" and "rain" also lack sufficient evidence. Therefore, the real reason for the extinction of the dinosaurs, there is a need for further exploration of.

EDCGold is a 2-up program that just might have seen better days, by today’s Internet Marketing standards. ECDGold is also known as Predator Marketing System. Predator/Dinosaur, pun intended or not, I hope to shed some light in this Review, concerning the pitfalls of making the wrong decision when choosing a home based business venture.
EDCGold is a direct sales company, very much like an online marketing training program, they specializes in digital products, and their latest claim to fame, is the Promo Black Box. This prides itself with being good at distributing proprietary Internet marketing software for all of their members.
You probably know that there are 3 ways to join the EDCGold membership program, however, here they are just in case you do not. 1. Easy Daily Cash Gold priced at $997 2. Easy Daily Cash “Normal” priced at $297 3. Your New Fortune priced at $69.95
Make sure you know what you are getting into should you decide to pay the $997 to join because remember EDCGold is a 2-up program, which means that you must give your first two sales to your sponsor, there is “NO Marketing Movie”, just a page full of testimonials which anybody can produce and NO Core System. Also, before investigating further I thought that EDCGold’s longevity was pretty much secure, however, when this information surfaced, I felt their longevity might be short lived.
You should be aware of two, of the most common issues that members, or should I say, X-members have with it, and are undeniably, issues of credibility. Let it be known that this is many voices that are all in agreement and not just a couple of people’s hearsay.
Issue #1.Owners Will “Not Promote EDCGold Anymore”
As recently as July 2007, there was a lot of talk on the Internet gossip line, when it was announced that EDCGold owners Craig and Mike decided to stop promoting their own business. You can imagine how a brand new member might feel, perhaps a bit left out in the cold, when hearing this news. When looking at the competition created by the owners, Craig and Mike, one would imagine that this would make it incredibly hard to sponsor anyone.
Issue #2. Name Calling and Bashing other Companies
Some Top earners that recently left it to join in other programs, claimed that Craig and Mike “made fool’s of them” in their emails for joining other programs. Craig and Mike also were caught bashing other competing programs, calling them scams. Unethical things happen in business, however, it is just sad to have to repeat this when it is the owners.
In conclusion, I feel business is business but integrity is a highly valued personality trait, by most of us. Even though they are good at a number of things, this lack of integrity, and the fact that the many of the leaders and top earners of the company, have got up and left, I believe, marks the end of this EDCGold/Predator Dinosaur.
