The earth was just cloud of dust after the "Big Bang". The earth exploded loudly with fire and rock. were in time to produce many things，which were to make the earth's atmosphere. As the earth cooled down，water began to appear onsurface. It allowed the earth to dissolve gases. Then life began to develop.
Small plants multiplied and filled the first oceans and seas with oxygen. This encouraged the development of early shellfish and fish. Land animals such insects, reptiles and dinosaurs appeared after green plants appeared. Small clever animals spread all the earth. They putting too much carbon dioxide into the atmosphere, which prevents heat from from the earth into space. Whether life will continue on the earth for millions of years to come will depend whether this problem be solved.

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.
