Our Earth is full of coloured creatures like insects, birds and cool amphibians. But why to extinct them? Are We too selfish?There have been many hundreds of anthropogenic extinctions in the last 500 years. Some examples indicate the extent of the extinction problem. In mammals, 76 species such as the Steller sea cow are extinct, 2 extinct in the wild (i.e. surviving only in captivity, SOC hereafter), and 29 possibly extinct. At least 134 birds, such as the passenger pigeon (Ectopistes migratorius) are extinct, 4 are SOC, and are 15 possibly extinct. Amphibians have been severely affected, and 159 such as the golden toad (Incilius periglenes) are extinct, one SOC, and 120 species are possibly extinct. In the case of reptiles, 21 species are considered extinct and one SOC, whereas among fishes 91 species are considered extinct.

After the big bang planet started to evolved. Then life emerged from randomness and due to carbon water combo or life came from extraterrestrial planet? Billions of years before Earth or our solar system were formed, space-journeying viruses and extraterrestrial microbes were deposited on planet after planet and continually exchanged DNA with species living on other worlds.
There are many temporal anamolies scattered through over the world that are enough to prove that our assumed history is wrong. I find them as strong evidences against our perceived view of evolution.The Paleozoic Era is a major division of geological time, preceded by Precambrian time and followed by the Mesozoic era, and including the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. The Paleozoic Era began about 570 million years ago and ended about 240 million years ago.
What will happen when we have no coal, no crude oil and almost no fossil fuel? Would our technological civilization die? Many advocates suggests uranium as a future energy source including Brian Wang of Next Big Future. However I find many implications which opposes the case of advocates. I’m not going to suggest alternative energy source right now as B.W. asks in his article [if nuclear fission is not the energy source of the future then weird science needs to compare and present what the alternative is that he supports], but be sure I will do it later with full analysis.
While terrestrial self-replicating systems may be limited for some time to coevolution with Earth-based industry constrained by normal economic factors, the prospect for extraterrestrial applications is quite different. The difficulty of surmounting the Earth’s gravitational potential makes it more efficient to consider sending information in preference to matter into space whenever possible. Once a small number of self-replicating facilities has been established in space, each able to feed upon nonterrestrial materials, further exports of mass from Earth will dwindle and eventually cease. The replicative feature is unique in its ability to grow, in situ, a vastly larger production facility than could reasonably be transported from Earth. Thus, the time required to organize extraordinarily large amounts of mass in space and to set up and perform various ambitious future missions can be greatly shortened by using a self-replicating factory that expands to the desired manufacturing capacity.
