Collins grew up in rural, apartheid-era South Africa in the 1970s. Her childhood inspired her to focus on empowering women living below the poverty line through grassroots efforts. The Wonderbag, which was inspired by watching her grandmother cook with cushions, uses heat retention technology to cook food for 8-12 hours without the need for additional fuel. Collins witnessed the benefits African women received from using Wonderbags, reducing the amount of time they spent collecting firewood. For every bag sold, another is donated to a household in Africa, and in the past four years, the Wonderbags have found themselves in 600,000 African homes. Collins has launched the Wonderbag in the U.S. on Amazon, and hopes to sell the products via other retailers by 2014.

Alternative Title: Panthera leo

Lion, (Panthera leo), large, powerfully built cat (family Felidae) that is second in size only to the tiger. The proverbial “king of beasts,” the lion has been one of the best-known wild animals since earliest times. Lions are most active at night and live in a variety of habitats but prefer grassland, savanna, dense scrub, and open woodland. Historically, they ranged across much of Europe, Asia, and Africa, but now they are found mainly in parts of Africa south of the Sahara. An isolated population of about 650 Asiatic lions constitute a slightly smaller race that lives under strict protection in India’s Gir National Park and Wildlife Sanctuary.

General characteristics

The lion is a well-muscled cat with a long body, large head, and short legs. Size and appearance vary considerably between the sexes. The male’s outstanding characteristic is his mane, which varies between different individuals and populations. It may be entirely lacking; it may fringe the face; or it may be full and shaggy, covering the back of the head, neck, and shoulders and continuing onto the throat and chest to join a fringe along the belly. In some lions the mane and fringe are very dark, almost black, giving the cat a majestic appearance. Manes make males look larger and may serve to intimidate rivals or impress prospective mates. A full-grown male is about 1.8–2.1 metres (6–7 feet) long, excluding the 1-metre tail; he stands about 1.2 metres high at the shoulder and weighs 170–230 kg (370–500 pounds). The female, or lioness, is smaller, with a body length of 1.5 metres, a shoulder height of 0.9–1.1 metres, and a weight of 120–180 kg. The lion’s coat is short and varies in colour from buff yellow, orange-brown, or silvery gray to dark brown, with a tuft on the tail tip that is usually darker than the rest of the coat.

Prides

Lions are unique among cats in that they live in a group, or pride. The members of a pride typically spend the day in several scattered groups that may unite to hunt or share a meal. A pride consists of several generations of lionesses, some of which are related, a smaller number of breeding males, and their cubs. The group may consist of as few as 4 or as many as 37 members, but about 15 is the average size. Each pride has a well-defined territory consisting of a core area that is strictly defended against intruding lions and a fringe area where some overlap is tolerated. Where prey is abundant, a territory area may be as small as 20 square km (8 square miles), but if game is sparse, it may cover up to 400 square km. Some prides have been known to use the same territory for decades, passing the area on between females. Lions proclaim their territory by roaring and by scent marking. Their distinctive roar is generally delivered in the evening before a night’s hunting and again before getting up at dawn. Males also proclaim their presence by urinating on bushes, trees, or simply on the ground, leaving a pungent scent behind. Defecation and rubbing against bushes leave different scent markings.

3. 需求弹性。解决价格低迷的方法就是低价。这是老生常谈,而且适用于供需两个方面。超低的原油价格会刺激需求复苏吗?某些国家对石油市场控制较严,低油价可能不会延伸到零售领域。印尼等国已经取消成品油补贴,这有利于国家财政,但消费者得到的实惠将减少。不过,美国汽油价格已跌破每加仑2.40美元,与2014年中期相比,降幅超过了35%。而此番降价已带动汽油消费的攀升。2014年底,美国汽油日消费量创2007年以来新高。低价可以提升需求,而需求的增长则可带动油价反弹。

Hunting

Lions prey on a large variety of animals ranging in size from rodents and baboons to Cape (or African) buffalo and hippopotamuses, but they predominantly hunt medium- to large-sized hoofed animals such as wildebeests, zebras, and antelopes. Prey preferences vary geographically as well as between neighbouring prides. Lions are known to take elephants and giraffes, but only if the individual is young or especially sick. They readily eat any meat they can find, including carrion and fresh kills that they scavenge or forcefully steal from hyenas, cheetahs, or wild dogs. Lionesses living in open savanna do most of the hunting, whereas males typically appropriate their meals from the female’s kills. However, male lions are also adept hunters, and in some areas they hunt frequently. Pride males in scrub or wooded habitat spend less time with the females and hunt most of their own meals. Nomadic males must always secure their own food.

Though a group of hunting lions is potentially nature’s most formidable predatory force on land, a high proportion of their hunts fail. The cats pay no attention to the wind’s direction (which can carry their scent to their prey), and they tire after running short distances. Typically, they stalk prey from nearby cover and then burst forth to run it down in a short, rapid rush. After leaping on the prey, the lion lunges at its neck and bites until the animal has been strangled. Other members of the pride quickly crowd around to feed on the kill, usually fighting for access. Hunts are sometimes conducted in groups, with members of a pride encircling a herd or approaching it from opposite directions, then closing in for a kill in the resulting panic. The cats typically gorge themselves and then rest for several days in its vicinity. An adult male can consume more than 34 kg (75 pounds) of meat at a single meal and rest for a week before resuming the hunt. If prey is abundant, both sexes typically spend 21 to 22 hours a day resting, sleeping, or sitting and hunt for only 2 or 3 hours a day.
