Europe is now the biggest market for organic food in the world, having grown by 25  percent a year over the past 10 years. Denmark's agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 90 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.

    So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides. Organic farmers rely on many  methods — such as crop rotation (农作物的轮作) and the use of resistant varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.

    Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture publicized that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims （宣称） made for organic farming is always true”.

    However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.

    Researchers are trying to figure out exactly when and where a lizard got trapped in the sap(汁、液) of a tree. Over time, the tree sap turned into amber (琥珀), preserving the lizard's mains, which a man discovered and donated to the Miller Museum of geology at Queen's University. But the man didn't report the amber's age and where he got it.

    “The man who donated it died, unfortunately,” said Ellen Handyside, an undergraduate student at Queen's University. “We are really starting from scratch in determining its history Ellen Handyside is leading the research into the amber-surrounded lizard. She and her colleagues analyzed the chemical composition of the 4.7-inch -long piece of amber and learned some facts. “The amber wasn't actually artificial,” she told Live Science, “and we found that it did match up quite well to an amber sample.”

    The researchers analyzed the amber's carbon and hydrogen isotopes(同位素) and the results indicated that the amber was formed from the sap of a flowering tree. Moreover, the results suggested that the tree and the lizard, for that matter, lived in an area with a lot of rainfall and dated to the Neogene, a period that lasted from the end of the Paleogene Period 23.03 million years ago to the beginning of the present Quatemary Period. Next, the scientific team realized that the 2.7-inch-long lizard was likely a gecko(壁虎), according to a detailed, 3D, digital model of the animal's body that the researchers created through X-ray microscopy scans.

“We looked at the skull —the teeth are in place and the ear bones are there too. And we've even got some flesh, skin and its long toes,” Handyside said. “It's fantastic!” She said she hoped that they could figure out how the creature fit into the gecko family tree. “When you think of a gecko, you think of short and fat toes and sticky pads. That isn't what we're looking at, but it's more likely to live in trees. If it were a tree-living creature, then its death actually could make more sense,” Handyside said.

Eco-Resort Management

    Ecotourism is often regarded as a form of nature-based tourism and has become an important alternative source of tourists. In addition to providing the traditional resort-leisure product, it has been argued that ecotourism resort(度假村) management should have a particular focus on best-practice environmental management. Couran Cove Resort is such a tourist attraction located on South Stradbroke Island, Australia.

    Sustainable(可持续的) Practices of Couran Cove Resort

    South Stradbroke Island is separated from the mainland by the Broadwater, which is home to a wide range of plant communities. Located on the offshore island, the Resort is only accessible by means of water transportation. It provides hourly ferry service from the harbour on the mainland to and from the island. Within the Resort, transport modes include walking trails, bicycle tracks and the beach train. The reception area is the counter of the shop which has not changed in 8 years at least. The accommodation is an octagonal(八角形的) building. These are large rooms that are clean but the equipment is old and in some cases just working. The ceiling fan only works at high speed for example. Beds are hard but clean. There is a television, a radio, an old air conditioner and a small fridge in each room.

    As an ecotourism-based resort, most of the planning and development of the attraction has been concentrated on the need to co-exist with the natural environment of South Stradbroke Island to achieve sustainable development.

Water and Energy Management

    There is groundwater at the centre of the island, which has a maximum height of 3 metres above sea level. The water supply is recharged by rainfall and is commonly known as an freshwater aquifer(含水层). Couran Cove Island Resort obtains its water supply by tapping into this aquifer and collecting it through a pipe. In order to narrow the water uses, all laundry activities are carried out on the mainland. The Resort uses LPG power station rather than a fuel oil station for its energy supply, supplemented(补充) by wind power, which has reduced greenhouse emissions by 70%. Hot water in the eco-cabins and for some of the Resort's vehicles is solar-powered. Water efficient fittings are also installed in showers and toilets. Visitors who stay at the Resort are encouraged to monitor their water and energy usage by an in-house television system, and are rewarded with prizes (such as a free return trip to the Resort) accordingly if their usage level is low.

    Evaluation

    In three years of operation, Couran Cove Island Resort has won 23 international and national awards. It has effectively implemented contemporary environmental management practices. However, the Resort's growth will eventually be limited by its carrying capacity, and quantity control should be incorporated in the management strategy of the Resort.

    Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

    The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, egg, bread and milk before going to school, he or she will learn more quickly and listen more carefully.

    The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight (增加体重) instead of losing it. You will lose more weight if you decrease your other meals.

The problem of food borne metal contamination (污染) has taken on new urgency, thanks in part to a 2021 US Congressional Report detailing high levels of metals found in baby food pulled off grocery shelves. More recently, high levels of lead (铅) were discovered in children's fruit puree pouches. Now, two new studies provide information on the correlation between exposure to heavy metals in food and the risk of cancers and other serious health risks.

Food crops can absorb heavy metals from contaminated soil, air, and water. As a result, traces of dangerous heavy metals — lead, arsenic (砷) and cadmium (镉) — are found in common foods from rice and cereals to nuts and vegetables. Felicia Wu, Michigan State University food scientist, is leading several investigations to gain a better understanding of the health risks of heavy metal exposure.

In the studies, Wu and her colleague, gathered data on the dietary intake of each metal from various sources such as food and water samples and existing studies and reports. There searchers analysand the data to determine the strength of the association between dietary exposure and bad health effects. Both cancer and non-cancer health effects were considered.

Lead is a poisonous metal commonly found in old paint, water pipes, and contaminated soil. Food sources of lead include root vegetables like beets. In the study, lead showed moderate (中度的) to high risk scores for causing lung, kidney, bladder, stomach, and brain cancers. It also showed moderate to high scores for non-cancer risks.

Their initial estimates suggest that every year, more than 6, 000 additional cases of bladder and lung cancers and over 7, 000 cases of skin cancers can be attributed (归因于) to the consumption of inorganic arsenic in the United States. The researchers also found that certain food products can be associated with higher cancer risk than others. These include rice, wheat, and leafy green vegetables.
