TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.

Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.

But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.

The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.

Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.

The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.

Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.

Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.

Among various programmes, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style. But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows.

Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as they can be. For example, the show takes the ever-mon talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.

Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.

pared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.

Clean as it is, the Oprah show is not for everyone. The show’s main viewers are middleclass Americans. Most of these people have the time, money, and ability to deal with life’s tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to-21-year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show’s exploitation.

A. Family ine planning.                       B. Nation hatred.
