3 . Michael Gonsalves, a chef of Golden Oak at Disney World, has a cuisine concept rooted in fresh, locally-sourced ingredients that originated from childhood harvesting produce from their family garden with his mom to eventually leading kitchens at Walt Disney World Resorts to employ a sustainable model.
“Truly the whole process starts with menu planning,” he said. Creating one dish leads into the creation of many more through the end-to-end use of products. As chefs, they are always searching for the best ingredients. It is then their focus to ensure they appreciate and respect all that go into each and every one of them. For example, they source chicken that is naturally grown and fed on a natural plant forward diet, no hormones (激素) or additives — that’s used in many ways throughout menus from a simple grilled chicken breast to bone soup. Nothing goes to waste.
When they do have waste, even if minimal, they shift it from landfills to transform it into compost (堆肥) that’s then used across the Walt Disney World property. They also support Second Harvest, a local community food bank where healthy produce, prepared, but not served, meals eatable for human consumption are donated. Disney also works with pig farmers when they can’t distribute foods past the point of safety for human consumption. Besides, wildlife reservations love to get the meat because tigers and wild cats can still eat that.
Their operations are “on a path to a sustainable zero waste kitchen of tomorrow” where chefs learn the full-life cycle of plants from seed to plate and gain a better understanding and appreciation for the product and their craft.
Golden Oak at Disney has millions of bees that produce up to 300 pounds of honey per year, plus those bees help with cross pollination (授粉) of their gardens on a daily basis. They advocate a culture that helps develop not only the quality of food, but an appreciation for nature.

6 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

9 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

10 . Climate change leads to a threat to the world’s sandy beaches, and as many as half of them could disappear by 2100, a new study has found. Even by 2050 some coastlines could be unrecognizable from what we see today, with 10% to 12% facing severe erosion (侵蚀).
Using updated sea level rise predictions, the researchers analyzed how beaches around the world would be in a future with higher seas and more damaging storms. They also considered natural processes like wave erosion, as well as human factors-like coastal building developments, all of which can affect a beach’s health. The study found that sea level rise is expected to outweigh these other factors, and that the more heat-trapping gases humans put into the atmosphere, the worse the influences on the world’s beaches are likely to be.
It’s hard to overstate just how important the world’s beaches are. They cover more than one third of the world’s coastlines, and protect coastal areas from storms. Beaches are also important economic engines, supporting relaxation, tourism and other activities. And in some areas, the beach is more than a vacation destination. In places like Australia, life near the coast revolves around the beach for much of the year.
Some of the world’s most popular beaches are already taking action. Places like Miami Beach are trucking in thousands of tons of sand to patch up (修复) badly eroded shorelines, while others have built sea walls and breakwaters in an attempt to hold precious sand in place. But the financial and environmental costs of these projects are huge, and scientists say rising seas and more powerful storms, supercharged by a warmer climate, will make this a losing battle.
However, the researchers did find that humans have some control over what happens to the world’s beaches. If the world’s governments are able to stick to modest cuts to heat-trapping gas pollution, the researchers found that 22%of projected beach losses by 2050 could be prevented, a number that grows to 40%by 2100 if greenhouse gases are limited.
