These satellite太空, 人造衛星 images show the ebb落潮 and flow流動（有規律的）漲落 of plant life on earth over three years, taken by a NASA satellite太空, 人造衛星 called SeaWiFS.
The blue areas are void of plants, the red spots indicate表明, 標示 an overabundance過多, and the green areas show where plants are thriving茁壯成長；興旺.
This is the earth breathing. The plants are taking up CO2, and they’re breathing out oxygen.
As suggested by oceanographers海洋學, almost half of that activity is going on underwater.
The oceans are teeming擠滿 with tiny microscopic極小 plants called phytoplankton浮游植物.
They are at the bottom of the food chain, and they basically feed all sea life.
Like all plants, phytoplankton浮游植物 absorbs CO2 from the atmosphere. 
    These images show that phytoplankton浮游植物 boomed over the last three years.
That’s one of the key benefits of these satellite太空, 人造衛星 images.
Over time久而久之, scientists will use them to help predict how plants might respond as we burn more fossil fuels礦物燃料, and as global CO2 levels rise.
Many scientists think such greenhouse gasses will cause global warming.
They suggest that it is related to recent climate change.
However, what they don’t know is how life in the ocean will respond over the long haul（用力）拉，拖（重物） if CO2levels keep rising.
