Mother Nature has it figured out. She's designed a master scheme that connects plants and animals, all working in concert to keep every living thing in balance.
This is especially obvious in places like central Africa and in South American tropical rainforests where certain animals help keep trees safe and healthy, which is critical as trees absorb vast amounts of planet-warming carbon pollution.
Recent research warns that losing the creatures that nurture trees puts forests in danger. This, by extension, is helping to accelerate dangerous climate change.
In central Africa, for example, elephants eat fast-growing trees, making room for those that grow more slowly. The slow-growing trees—with their very dense wood—store more carbon than the thinner, faster-developing ones. Without elephants, more carbon would accumulate in the atmosphere, worsening climate change, according to a new study that used computer models to project what could happen if elephant populations continue to decrease or become extinct.
“Africa may once have contained 10 million elephants from the Mediterranean to the Cape, in every habitat except extreme desert. In 1970, there may have been a million left. By the end of
the 1980s, there were half that number, mostly killed for the ivory trade，” said Stephen Blake, assistant professor of biology at St. Louis University.
By killing elephants, poachers(偷猎者) rob slow-growing trees of their guardian. They also slow the growth of new trees. Elephants blaze(开辟) trails and disperse(散播) seeds as they look for food “Elephants are basically the gardeners of the forest，” Blake said. “They disperse over 100 species of seeds, and disperse more of them over longer distances than other dispersers.”
Blake, who has spent nearly 20 years in Africa working in elephant research and conservation, mourns their fate, describing them as “a complex society of intelligent, caring emotional animals who respect their grandmothers and mourn their dead，” and condemns those who neglect their duty to save them.
“We will go to Mars—there is no doubt—humans are too smart not to，” he said. “Yet we do not have the wisdom to protect elephants and their forest environment that do so much for our physical, spiritual, and emotional well-being.”

London, New York, Tokyo and Paris—these famous cities have a commanding influence on
the world economy and are home to millions of people, as well as internationally famous arts, culture and educational institutions. But they are hardly representative of the rest of the world's cities. While 54% of the global population live in cities, around half of those live in cities that have 500，000 inhabitants or fewer.
These “ordinary” cities can be overlooked by politicians, investors, researchers and big businesses. But they are dynamic places with many layers of social, cultural and economic significance. After experiencing a period of post-industrial decline, many such cities are considering urban regeneration(再生) programmes.
But that doesn't mean they have to follow the same path as other urban areas. In fact, the research into urban development has found that ordinary cities can avoid some of the ill-effects of regeneration, by embracing what makes them unique.
At the turn of the century, city leaders became increasingly interested in the idea of the “creative city”. The idea was to encourage a “creative class” of talented workers to make their homes and businesses in cities, by creating urban spaces that are open, inclusive and diverse, as well as attractive and technologically advanced.
“Regeneration” became a buzzword associated with these types of strategies, which seek to repurpose seemingly disused or rundown spaces to support an economy led by creative and technological industries. The apparent success of creative city policies was seen in post-industrial centres such as Detroit, US, following investments in cultural, artistic and musical urban renewal.
Such policies swiftly became the go-to strategy for seemingly “ordinary” post-industrial cities around the world, even resulting in new rankings that pit cities against each other, based on criteria including entrepreneurship(创业精神), urban leadership and “liveability”. Having plenty of former industrial spaces that can be adapted for new uses, and a desire to be noticed on the national or global stage, encourages investment in urban regeneration from both public and private sources.
Yet regeneration programmes inspired by the creative city agenda can cause problems. Property developers(地产开发商) and foreign investors have recognized the economic potential of real estate(房地产) in “creative” cities. This has led to rocketing land costs, and many low-income residents have felt the effects of being displaced from their homes.
Yet as more cities seek to emphasize their cultural assets(资产), city leaders and policy
makers must be aware of the negative impacts that can arise if local residents are not central to the decision-making process. This emphasizes the need to consider local contexts and communities before operating copycat creative policies.
( )61. Some famous cities can't represent the rest of the world's cities in that ________． A. they are always ignored by politicians, researchers and businessmen
B. they accommodate millions of people but don't contribute to the world economy C. about a quarter of global population live in middle-sized and small cities D. not all famous arts, culture and educational organizations are distributed there
( )62. What measure was probably taken by cities like Detroit to promote city development?
A. Using culture and art as a driving force. B. Forcing low-income residents to move. C. Following the same path as some big cities. D. Encouraging industrial investment continuously. ( )63. What does the author want to stress in the passage? A. Cities should copy regeneration programmes.
B. Cities should compete with each other based on some criteria. C. Cities should seek financial support from sources around the world. D. Cities should consider regional factors before using creative policies. ( )64. What does the passage mainly talk about?
A. Ordinary cities successfully avoid ill-effects of development. B. Ordinary cities don't have to copy trends to regenerate.
C. Ordinary cities are trying to recover from post-industrial decline. D. Ordinary cities are dynamic places with social importance.
