地球上に最初の生命が現れた時から、種は絶滅してきた。
絶滅とは進化の自然な過程なのである。
その環境にもっとも適した種が生き残る。
他の種は、瞬時に十分に適応することができず、故に死に絶える。
ではなぜ、今日絶滅危惧種がこんなにも注目をあびるのであろう?
ひとつの理由は、今日起っている多くの絶滅が、不自然だからである。
種が絶滅危惧となる主な理由は、生息地の喪失にある。
生息地が破壊される数例をあげると、人間が農地用に森林を伐採し、都市を拡大し、水路を汚染するので、動物、植物そして昆虫たちはどんどん生き残るのが困難になっているのだ。
このように、自然界における人間の影響が、種が絶滅の危機に瀕する原因を引き起こし、ひいては絶滅するのだ。
種が絶滅の危機に瀕するもう一つの主な理由は、気候変動である。
例えば、この記事の中に出てくるトカゲはおそらく、気温の段階的変化に適応することができるであろう。
しかし、気候の急激な変化とその結果としてのトカゲの出生率の減少は、多くのトカゲ種を破滅へと導く恐れがある。
人間の活動が気候変動の主な理由であるならば、我々は自分達の世界を種が自然に適応できないほどあまりにも急速に変えているように思える。
人間はものすごく適応性が高いが、ほとんどの種は変わり行く状況に慣れるために沢山の時間を必要とするのだ。

    By 2080, global warming could result in one-fifth of the world’s lizard species becoming extinct, a global study has found. Even under the most optimistic scenarios for curbing carbon dioxide emissions, the analysis by an international team shows that one-fifth of the globe’s lizard populations, corresponding to 6% of all lizard species, may go extinct by 2050. “We’ve committed ourselves to that,” says Barry Sinervo, an evolutionary biologist at the University of California, Santa Cruz, who led the study. He and his colleagues found that climate change has already driven 12% of the populations of Mexico’s colourful Sceloporus lizards extinct since 1975. If emissions continue at current levels, he predicts that by 2080, 39% of the world’s lizard populations will have vanished, corresponding to a 20% loss in species. The study is published in Science this week. It’s a stunning finding, says Raymond Huey, an evolutionary physiologist at the University of Washington, Seattle, who wasn’t part of the study team. “Lizards are animals that should be very tolerant of climate warming,” he says. よろしくお願いします^^;...

    Evolutionary biologists such as Dr. Barry Sinervo research the origin of species and how they adapt to their environments. Dr. Sinervo specializes in lizard species. His team went to various sites where a particular lizard species lives. He and his team were investigating the effect of the lizard’s colorful appearance on its evolution. Unfortunately, the lizard species they were looking for turned out to be hard to find. Thus, the focus of their research changed from “how did the lizard’s appearance help it survive and evolve?” to “why is this species going extinct?” Habitat destruction is the most common reason for species to disappear from the Earth. However, the lizards were living in protected areas which were untouched by human activity. Thus, the team investigated alternative explanations for the disappearance of the lizards....

    In their efforts to "buy green",customers tend to focus on packaging and chemicals, issues that do not factor in with clothing. Likewise, they purchase “natural” fibers like cotton, believing they are good for the environment. But that is not always the case: while " organic "cotton is exemplary in the way it avoids pesticides, cotton garments squander energy because they must be washed frequently at high temperatures, and generally require tumble-drying and ironing. Sixty percent of the carbon emissions generated by a simple cotton T-shirt comes from the 25 washes and machine dryings it will require, the Cambridge study found. A synthetic blouse, in contrast, takes more energy to make, since synthetic fabrics must be processed from materials like wood and oil. But upkeep is far more fuel-efficient, since synthetic fiber clean more easily and dry faster. Over a lifetime, a synthenic blouse uses less energy than a cotton T-shirt. One way to change the balance would be to develop technology to treat cotton so that it did not absorb odors so readily. "Reducing" washing temperature has a huge impact,” Allwood said....

    Does the Earth have the natural resources to support this many people? Unfortunately, the answer to this question depends on information we don't have. For example, we don't know how people will choose to live in the future. We don't know what their standard of living will be. We also don't know what new technologies will be available in the future. We do know that the Earth's natural resources are limited. Fresh water, for example, is crucial for health and food production. However, more than 97% of the water on Earth is salt water, which is poisonous to both people and crops. Only 3% of the water on Earth is fresh water, and three quarters of that fresh water is frozen at the North and South Poles. Today, the demands for fresh water is greater than the supply in roughly eighty countries around the world. By 2025, scientists predict that forty-eight countries will have chronic shortages of water. At present, disalinization, or the removal of salt from salt water, is not a solution to the shortage of fresh water. It takes a lot of energy to remove the salt from ocean water, and that makes the disalinization process very expensive....

    Scientists at NASA and the University of Kansas say that a mass extinction on Earth hundreds of millions of years ago could have been trrigered by a stear explosion called a gumma-ray burst. The scientists do not have direct evidence that such a burst activated the ancient extinction. The strength of their work is their atmospheric modeling - essentially a“what if”scenario. The scientists calculated that gamma-ray radiation from a relatively nearby star explosion. hitting the Earth for only ten seconds, could deplete up to half of the atmosphere's protective ozone layer. Recavery could take at least five years. With the ozone layer damaged,ultraviolet radiation from the-Sun could kill much of the life on land and near the surface of oceans and lakes,and disrupt the food chain. (崩して訳してる部分もあるんですが…) NASAとカンザス大学の科学者達は、一億年前の地球で起こった大量絶滅はガンマ線バーストと呼ばれる星の爆発が引き金になりえるだろうといった。 科学者達はバーストによる太古の絶滅過程への直接的な証拠は持ってはいない。 彼らのこの仮説は、大気モデルに“もしあったら”というシナリオ的な要素を含んでいる。 科学者達は近距離の星の爆発から放射されるガンマ線がどう関係するかを計算した。 それが約10秒地球に降り注げば、大気を保護するオゾン層の半分が激減し、それが回復するのに少なく見積もっても5年はかかるだろう。 オゾン層の破壊は、太陽から降り注ぐ紫外線により、地表、海洋表面や湖における食物連鎖を破壊し、多くの生命を死滅させる。...
