According to a new scientific research, we are rapidly going close to major climate change and the effects on the environment could be quite serious. Geographers predict that climate zones could completely disappear within the next eighty years. Where will crops be grown if this happens? When the climate changes a lot, polar regions will get colder and tropical regions will get even hotter. As a result, where will animals be forced to move on the earth?

    Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes(飓风) will not only increase but may also become stronger. If the changes come too quickly, animals and plants may not be able to adapt(适应) right away and could disappear from the earth.

    According to Science Daily, a new study predicts that, by the year 2100, many of today's familiar climates will be taken place by climate unknown in today's world. It is urgent that we reduce the risks of far-reaching results for the whole world. The planet itself has been showing signs of change. In 2004, a huge tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands more died in China in another big earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was destroyed seriously and became ruins in 2010 by another big earthquake.

    Not long ago, scientists discovered ice melting(融化) in west Antarctica(南极洲). This is very worrying because temperatures in this area have remained rather constant(不断的) and actually even lower at time. Melting occurs when temperatures increase and since temperatures have remained, the ice should not be melting. However, satellite data(数据) shows melting around west Antarctica.

    Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously expected. At this point, it doesn't matter what is causing it, but rather, what can be done about it. On the other hand, our world is getting more and more unstable(不稳定) every year. Natural disasters(灾难) are becoming more frequent(频繁的) and serious.

    However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connections between these. No one knows anything for sure at this point because there is simply not enough data.

    When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows- cow manure(粪肥).

    Cows produce a lot of waste. One cow can create 30 gallons of waste each day. Now imagine the output of over 1,000 cows at Blue Farm. That's really a big amount.

    When farmers clean their barns, they put the waste together，and spread some of it on their fields for fertilizer(肥料). But now places like Blue Farm have a new way of using cow waste. They use it to produce electricity.

    Here's how it works: A big machine moves back and forth cleaning the barn floor. "The cows are animals of habit; they get used to it,and just lift one foot and then another to let it go by. "says Marie Audet.

    The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester(化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.

    Methane gas(甲烷;沼气) in the atmosphere is known as a "greenhouse" gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That's an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators(发电机).

    At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can't use themselves.

Many countries have special holidays that celebrate important events in their past. For example, the United Statc s has Independence Day on July 4th. France has Bastille Day op July 14th. And in Chile, they cclebrate the Fiesta s Patrias on September 18th. But Chile doesn't spend only one day celebrating its independence. It is celebrated for at least two days, September 18th and 19th. 

These two official days are referred to as Dieciocho("eighteen, " pronounced dee-cee-oh-cho)because they start on the 18th. September 19th is celebrated as the Day of the Glory of the Armies. It marks the victory of winning the Spanish army in wars. It is also time to celebrate the end of winter, which in Chile appears during July and August, and the coming of summer, which begins in December. Sometimes 26 festivities might go on for an entire week, and many schools and businesses close for that week so people can travel and celebrate with their families. 

How is Fiesta s Patria s celebrated? There are parades, music and dancing, lots of amazing food and drink, and many partics. Most of all, it is a time for Chilcans to cclebrate their culture and customs. Many men and women dress in traditional Chilean outfits. 

Many small towns and cities begin their celebrations with traditional parties called fondas. These fondas feature live cueca music and dancing. Cueca is a type of music from Chile, Argentina, and Bolivia, and is played with guitars, accordions, percussion, and guitarrons (a large bass gutar) La Cueca is Chile's national dance It is one of the most important parts of celebrating Fiesta s Patrias. Everyone can learn the dance quickly. They work in pairs and mimic(模仿) the courting dance of a rooster and a hen. The partners hold hands using a cloth, and they stomp(跺脚)and circle cach other. Couples often compete to sc e who is the best cueca dancer. 

Dicciocho is a great time to visit the country and experience Chilean culture, food, and fun. Just make sure to bring your dancing shoes and your appetite.
