Biofuels (生物燃料), gained from plants and animal matter, are a key solution to the environmental problems caused by fuels like coal. "Bioalcohol (生物酒精) is the most common biofuel and is produced by sugars found in materials such as corn. With some engine redesigned, it can be used directly by cars, buses, etc. ," says Professor Daniel Tan, "12 percent of transport fuel could come from biofuels, especially bioalcohol, by 2030. "

But a 2016 study of biofuels said, "Bioalcohol presently is mostly produced with food crops. Altogether, the environmentally-friendly biofuels rely on about 2-3 percent of the global water and land used for agriculture, which could feed a large number of hungry people. "

Energy experts have therefore been trying to deal with the problem. Recent research led by an international team found that the agave (龙舌兰) plant might offer a way out. This plant tends to be the right bioalcohol source to supersede others such as sugarcane (甘蔗) and corn.

Daniel Tan explains that the agave can be grown in unfavorable conditions and is not a major food crop. "It can grow in areas that lack water and rainfall without being watered by farmers, and it does not compete with food crops or put demands on limited water. This kind of useful plant is recently being grown in Australia. It can survive Australia's hot summers," he says.

The study finds that sugarcane produces just a little more fuel per square meter each year than the agave. However, the agave outperforms sugarcane in a range of areas, including pollution to the earth, and water using. The agave uses 69 percent less water than sugarcane and 46 percent less water than corn for the same amount of fuel produced. As for corn,it produces less fuel per square meter each year than the agave.

However, Daniel Tan states: "The first generation of bioalcohol from the agave recently faces a big competition from oil, whose recent low price makes it far more attractive to customers. Without some policy support from the government, bioalcohol production from the agave faces big challenges. "

BLOOD DRIVE & MARROW(骨髓)REGISTRATION

    "These patients deserve a chance at a normal, happy future and they rely on the kindness of the strangers to make that happen.

    — Daisy, Isabelle's Mother

    Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2008 Isabelle was diagnosed(诊断)with a genetic blood disorder,beta thalassemia. Isabelle's body is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6weeks since she was 11 months old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant.  Isabelle is an only child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.

    Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They began to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.

    Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.

    On the other hand, if there is not enough tourism, people can lose jobs. Business can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first­class roads, and other support facilities needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owner of the hotel lose money.

    Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.
