Although nuclear power has
its drawbacks and limitations , still seems to be the
primary choice for energy production today due to the rise
in population and to general energy consumption around the
world as well as to the lack of technology in the other
fields of energy production .
When a former anti-nuclear campaigner and founding member of Greenpeace proclaims in the Washington Post “the environmental movement needs to update its views…because nuclear energy may just be the energy source that can save our planet from another possible disaster,” we should pay attention....
Nuclear power pros and cons ielts essay models
When one electron shell is filled, electrons begin to fill shells farther from the nucleus. For the simplest atoms it works that way, but for larger atoms, particularly those of metallic elements, electrons fill shells in more complex fashion and electrons begin to fill subshells not necessarily in the shell closest to the nucleus. When an electron is unpaired or in an unfilled shell, it can be a electron, which can form bonds with other atoms. In most circumstances, only unpaired electrons form bonds with other atoms. Electron bonds between atoms provide the basis for chemistry and life on Earth.
Essay: Nuclear Energy – Advantages and Disadvantages
Monkeys, apes, and humans have many traits in common, and one is that members of "out-groups" are fair game. Chimpanzees are the only non-human animals today that form ranked hunting parties, and they are also the only ones that form hunting parties to . Distinct from the killer ape hypothesis, which posits that humans are instinctually violent, the chimpanzee violence hypothesis proposes that chimps only engage in warfare when it makes economic sense: when the benefits of eliminating rivals outweigh the risks/costs. Macaque wars and revolutions appear spontaneously, but chimp wars have calculation behind them, which befits a chimp’s advanced cognitive abilities; they plan murderous raids and carry them out. It is quite probable that the advancing toolset of protohumans was used for coalitionary killing when perceived benefits exceeded assessed risks/costs. Just as with , these traits probably also existed in our last common ancestor. Other animals also engage in intra-species violence, which includes spiders when key resources are scarce and contested, and when ant colonies have power imbalances, they can trigger invasion and extermination by the larger colony. But human and chimpanzee warfare is uniquely organized and calculating.

Other than humans, rhesus macaques are Earth’s most widespread primates, and both species are generalists whose ability to adapt has been responsible for their success. Rhesus macaques are , about twice that of dogs and cats, and nearly as much as chimpanzees. Rhesus macaques have what is called Machiavellian social organization, in which everybody is continually vying for rank and power is everything. Those with rhesus power get the most and best food, the best and safest sleeping places, mating privileges, the nicest environments to live in, and endless grooming by subordinates, whom the dominants can beat and harass whenever they want, while those low in the hierarchies get the scraps and are usually the first to succumb to the vagaries of rhesus life, including predation. It is the . But even the lowliest macaque will become patriotic cannon fodder if his society faces an external threat, as even a macaque knows that a miserable life is better than no life at all. The violence inflicted seems economically optimized; within a society the violence is mostly harassment, but when rival societies first come in contact, the violence is often lethal, as the initially established dominance can last for lifetimes. Within a society, killing a subordinate does not make economic sense, as that subordinate supports the hierarchy. Potentates rely on slaves. The human smile evolved from the teeth-baring display of monkeys that connotes fear or submission.
