Experts say that if food were a country, it would rank second behind the US as one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for14.5 percent of global greenhouse gas methane(甲烷) emissions(排放). While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.
Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources, While going vegetarian(素食的)would help meat consumption too deep - rooted in most western diets to allow for such a sharp, permanent change. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects！
Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic(驯养的) animals. They also require much less room，use less water and food, and produce far less greenhouse gas than animals
Of the 1.1 million insect species worldwide, scientists have identified 1.700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat
While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated(饱和)at found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup make baked treats, and even fry a few with vegetables. So eat insects -both your body and Mother Earth will thank you for it ！

By the time Robert Porter Allen was born in 1905, the whooping crane(鸣鹤)was already in trouble. The beautiful bird was once commonly found across North America. By 1941, the whooping crane population had dwindled to the double digits. The tallest species in North America were critically endangered.
In the 1940s, the remaining cranes migrate(迁徙) every year from the Gulf Coast of Texas to somewhere in the north of Canada to breed(繁殖). The conservation community didn’t know where the birds went. The wetlands where they used to spend winters were growing rarer and rarer as they tiny, non-migrating group of whooping cranes was alive in Louisiana in 1941, but the group had disappeared by the time Allen started his research.
In 1942, Allen undertook the whooping crane project Over the next three years, he did almost constant field work that took him from Texas up the cranes' migration route to Nebraska, and on into Saskatchewan in search of the nesting ground of the birds.
Studying the bird in its breeding habitat and seeing how many birds were born would allow conservationists to understand how to help the birds on their journey. But finding the whooping crane 's nesting site meant difficult and fruitless air searches over northern Canada.
In 1952, Allen wrote a report on the whooping crane. The report was a warning call to the conservation community: only 33 migratory "whoopers" remained, and their nesting site still hadn’t been found. Two years later, the whooping cranes breeding grounds in Canada's Wood Buffalo National Park were finally found, and Allen headed north to study them firsthand, an "incredibly difficult journey, "in Sprunt’s words, Allen’s work laid the groundwork for conservationists to save the birds.
Their efforts paid off as the numbers reached 57 by 1970 and 214 by 2005.Today, the whooping crane is still listed as endangered, but there are roughly 600 birds alive.

2.What does the underlined word “dwindled” mean in the first paragraph?
