Passage 29
学霸导读 气候变化除了会给动物带来危害外，对人类又有哪些不利影响呢？
Due to climate change， the world’s endangered （ 濒危的 ） lists are no longer just for animals. We may not only need to adapt ourselves to living in a warmer world but a less tasty one as well.
As the increased amount of carbon dioxide in the air c 1 to affect weather， we often forget that they are also impacting the quantity， the quality， and the growing locations of our food. Some foods have already felt the impact while others may even become scarce （ 稀缺 ） within the next 30 years.
Whether or not you try to limit yourself to one cup of coffee a day, the effects of climate change on the world’s coffee-growing regions may l 2 you little choice.
Rising temperatures and unpredictable rainfall patterns （ 降雨模式 ） are reported to have been threatening coffee plantations in South America， Africa， Asia， and Hawaii. The r 3 ？ Signif icant cuts in coffee yield （ 产量 ）.
According to organizations like Australia’s Climate Institute, half of the present coffee-producing areas are estimated not to be suitable by the year 2050, if current climate patterns continue.
Oceans are absorbing some of the heat and undergoing （ 经历 ） warming of their o 4 . This causes a decline in f ish population， including in lobsters that are cold-blooded creatures， and in salmons （ 鲑鱼 ） whose eggs f ind it hard to s 5 in higher water temperatures. Warmer waters also encourage some poisonous marine bacteria to grow and lead to illness in humans whenever taken with raw seafood， like oysters.
And how about that satisfying “crack （ 咔嚓声 ）” which you get when you are eating crabs and lobsters？ It could be silenced because shellf ish have been struggling to b 6 their calcium carbonate （ 碳酸钙 ） shells which is a result of ocean acidif ication （ 酸化 ）.
Even worse is the possibility that we will have no seafood to enjoy at all. In a 2006 Dalhousie University study， scientists predicted that if overf ishing （ 过度捕捞 ） and rising temperature trends continued at their present rate， the world’s seafood stocks would r 7 out by the year 2050.
