Protecting certain animals and increasing the number of several animals could help 46(to) reduce global warming (全球变暖), according to a recent study by scientists from Yale University in the US. As too much $CO_2$ is given off into the air, the earth's surface temperature is 47slowly rising.
It's well known that plants take in $CO_2$. But Schimitz and his team from Yale University 48found that animals can help too. They looked at the data (数据) collected by other scientists on the environmental effects on certain wild animals. For example, elephants eat plants that compete with carbon-eating(食碳能力) trees for sunlight and water. Elephants also help plants grow through their poo(粪便). Whales encourage the 49growth of carbon-eating tiny animals and plants. That is because the animals and plants feed on the 50whales' poo. These tiny animals and plants are 51helpful because they take in around 40% of all the $CO_2$ that is produced by human activities. They also give off lots of $O_2$, so they are great for the planet.
Using this information, Schimitz and his team 52worked out a result. The global goal of reducing carbon output could be met by 53keeping the populations of some animal groups unchanged. What's more, the number of some animals 54was in need of increase. Together, these animal groups could help to take in about 6.41 billion tons of $CO_2$ every year. That could stop global warming from reaching 55dangerous levels.

答案： 46. (to) reduce 47. slowly 48. found 49. growth 50. whales' 51. helpful 52. worked 53. keeping 54. was 55. dangerous
