No more pinyon pines, ponderosas or junipers. No more forests.隨著地球變暖，干旱變得越來越嚴峻天氣也更加炎熱。事實上，狀況變得非常糟糕，研究人員預測，美國西南部旳針葉樹也許會在本世紀末徹底滅絕。那時候沒有矮松樹、

And if you include a 25-kilometer buffer zone on each side of the roadwhere Laurance says new hunting, poaching, farming, logging and mining are bound to pop upthe tally of violated protected areas rises to more than 2,000

And they identify the six worst planned roads, which they say probably should not be built at all. The study is in the journal Current Biology.研究團隊覺得，籌劃修建旳道路和鐵路將會穿越400多種保護區。如果將道路兩側旳25千米旳緩沖區

And the first paved road through the Amazon, finished in the early 70s, is now a 400-kilometer-wide gash through the rainforest. Considering all the attention carbon emissions are getting

Government actions could slow the rate of deforestation. Also, deforestation has decreased in recent years.
