Is climate change consuming your favorite foods?

    Coffee: 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 leave you little choice. {#blank#}1{#/blank#} America, Africa, Asia and Hawaii are all being threatened by rising air temperatures and unstable rainfall patterns, which invite disease and {#blank#}2{#/blank#} species to live on the coffee plant and ripening beans. The result? Significant cuts in coffee yield and less coffee in your cup. It is estimated that, if current climate patterns continue, half of the areas {#blank#}3{#/blank#} suitable for coffee production won't be by the year 2050.

    Tea: When it comes to tea, warmer climates and erratic precipitation aren't only {#blank#}4{#/blank#} the world's tea-growing regions, they're also messing with its distinct flavor. For example, in India, researchers have already discovered that the Indian Monsoon has brought more intense rainfall, making tea flavor weaker. Recent research coming out of the University of Southampton suggests that tea-producing areas in some places, {#blank#}5{#/blank#} East Africa, could decline by as much as 55 percent by 2050 as precipitation and temperatures change. Tea pickers are also feeling the {#blank#}6{#/blank#} of climate change. During harvest season, increased air temperatures are creating an increased risk of heatstroke for field workers.

    Seafood: Climate change is affecting the world's aquaculture as much as its agriculture. As air temperatures rise, oceans and waterways absorb some of the heat and {#blank#}7{#/blank#} warming of their own. The result is a decline in fish population, including in lobsters (who are cold-blooded creatures), and salmon (whose eggs find it hard to survive in higher water temps). Warmer waters also {#blank#}8{#/blank#} toxic marine bacteria, like Vibrio, to grow and cause illness in humans whenever ingested with raw seafood, like oysters or sashimi.

    And that {#blank#}9{#/blank#} "crack" you get when eating crab and lobster? It could be silenced as shellfish struggle to build their calcium(碳) carbonate shells, a result of ocean acidification (absorb carbon dioxide from the air). According to a study, scientists predicted that if over-fishing and rising temperature trends continued at their present rate, the world's seafood {#blank#}10{#/blank#} would run out by the year 2050.

    Eco-tourism involves people travelling to beautiful but environmental sensitive place. Such trips are usually carried out with a(n) {#blank#}1{#/blank#} guide. Over recent years  this type of travel has been steadily gaining {#blank#}2{#/blank#} as more people search for new travel experiences.

    It is obvious that eco-tourism is beneficial in many aspects. First, all the money spent by the tourists is used to {#blank#}3{#/blank#} the important environmental spots they visit. Second, it helps visitors to better understand the environment, which is sure to {#blank#}4{#/blank#} their knowledge of the world. Furthermore, this style of travel is also more {#blank#}5{#/blank#} of the local culture.

    Compared to normal tourists, eco-tourist use energy more {#blank#}6{#/blank#}, save water and produce less rubbish by finding ways to recycle it. These behaviors have a(n) {#blank#}7{#/blank#} and lasting effect on the local environment.

    Two things are needed to make eco-tourism a success. First, it should be done in small groups. And second, because it requires {#blank#}8{#/blank#} effort, both eco-tourists and locals must be sincere in their devotion to improving the environment.

    Green travel provides local people with jobs in parks, hotels and shops. One great achievement of eco-tourism has been the {#blank#}9{#/blank#} of illegal hunting. Former hunters can now work as guides to help keep the animals safe in their natural surroundings.

Peru is one country using eco-tourism to promote respect for the environment. It's not able to take better care of its rainforests because of {#blank#}10{#/blank#} on more sustainable travel.

    In addition to this, local people's living-standards have improved. Many others are now following Peru's example and using eco-tourism to preserve their environment for the future generations.

b. I think you are doing an {#blank#}2{#/blank#}job with those children.
