On the 23.03.2010 the BBC reported online that science has a new theory about the ascendancy of the Dinosaurs.

According to the report it was caused by immence volcanic activities 200 million years ago, which changed the climatic conditions in favor of the Dinosaurs.

Some 140 million years later, so the scientific theory, a asteroid or comet wiped them out because the impact changed the climate yet again.

So far the theory. Let’s add a new theory to the old one.

Perhaps the reason for the extinction of the Dinosaurs was because the pure size of the beasts and their numbers were unsustainable for the ecosystem of planet earth?

The question which we as human beings have to ask ourselfs, is whether the sheer mass of human population and the technological impact of our race will become unsustainable for nature and nature, as a result, will try to get rid of human being just as it got rid of the dinosaurs.

Although this thoughts are scary, the question must be asked and wether a new way of living within nature is the challenge we all have to meet.

Climate Change, and that is fact, endangers live on earth. And human race is only part of nature. Humanity must adept to nature and not the other way round!

    Pretty insightful post. Never thought that it was this simple after all. I had spent a good deal of my time looking for someone to explain this subject clearly and you’re the only one that ever did that. Kudos to you! Keep it up

    Climate change had little to do with the demise of the dinosaurs, but the last million years before their extinction had a complex pattern of warming and cooling events that are important to our understanding of the end of their reign.

    An extraterrestrial object that impacted the Earth near the Yucatan in Mexico 65.51 million years ago doomed the dinosaurs and 70 percent of the Earth’s other species, vaporizing itself and the surrounding rocks and throwing enough ash, soot and debris into the atmosphere to effectively stop photosynthesis worldwide. This impact radically altered the natural progression of evolution. The time of the impact is called the K-T boundary and marked the end of Cretaceous Period and the beginning of the Tertiary Period.

    It could be argued that we are still recovering from that impact and the mass extinctions of dinosaurs, mammals, insects, plants and sea life that it caused, For example, not only the dinosaurs, but also 80 to 90 percent of the Cretaceous plant species, including all the dominant species, disappeared.

    Luckily, the K-T extinction occurred during a short interval in the Earth’s magnetic pole reversals. Periodically, the Earth’s poles switch polarity making North negative and South positive. Eventually, another switch occurs making North positive and South negative. A record of the Earth’s paleomagnetism is recorded in the rocks as they are laid down.

    The K-T impact affected the Earth’s living things severely and dramatically, but the climate changes right before the impact, by comparison, did not.

    Dinosaurs had to cope with dramatic swings in the climate around 120 million years ago, with ocean surface temperatures changing by as much as 6 °C. The finding suggests that natural climate variations are much more complex than previously thought. The era of the dinosaurs did not end because they were in decline but rather they were changing into creature that were more diverse, more active and more cerebral (brainy),therby more similar to modern birds and mammals.
