Desertification

    Desertification is one of the world's most alarming processes of environmental degradation(退化). The issue is often unclear, however, by a common misperception: that it's a "natural" problem of advancing deserts in faraway developing countries. In fact, desertification is about land degradation: the loss of the land's biological productivity, caused by man-made factors and climate change.

    Each year, desertification and drought cause an estimated $42 billion in lost agricultural production. The risks of desertification are sufficient and clear. It contributes to food insecurity, hunger and poverty, and can give rise to social, economic and political tensions that can cause conflicts, further poverty and land degradation. The great urgency of this challenge led the United Nations General Assembly to state 2006 to be the International Year of Deserts and Desertification (IYDD). It is a strong reminder of the urgent need to address the far-reaching implications of this problem. United Nations General Secretary recently summarizes in this way: "I look forward to working with Governments, civil society, the private section, international organizations and others to focus attention on this crucial issue, and to reverse the trend of desertification and set the world on a safer, more sustainable path of development."

    The IYDD also presents a golden opportunity to get the message across strongly and effectively that desertification is a global problem which we ignore at our risk. It is important to recognize that dry-lands are home to some of the most magnificent ecosystems of this world. These unique natural habitats have been home to some of the world's oldest civilizations. They stand like open-air museums, bearing witness to bygone eras. The Year will therefore also celebrate the delicate beauty and unique inheritance of the world's deserts.

    Over the past few years, there has been a big increase in the number of people sharing information online. In this article we will learn about some positive factors for people to share information online.

    We often share information with our friends in the office or at home to educate, entertain or pleasantly surprise them. In this way we can connect with others. This is also true while sharing information online. If you look at the Facebook wall posts of your friends, you will realize that most of their updates are usually famous quotes, entertaining videos, inspirational images, funny jokes, etc. 94% of those who responded to a survey by the New York Times said they put a lot of thought into how the content they are sharing will be beneficial to others.

    A lot of people share information online to represent their true self to the outside world. Some people, especially those who are shy and not comfortable talking about their areas of interest in the presence of others, find it extremely convenient to share that information online with like-minded individuals.

    78% of the respondents in the study of The New York Times said they shared information online because it helps them develop better relationships. Today, a lot of people do not have the time to meet each other in person and the Internet has become a great substitute. A lot of people now "meet" each other online, rather than in conventional places like restaurants and pubs.

    Lastly, when we share our thoughts online, we are actively engaging with the vast community of people who are a part of the World Wide Web. Sharing information will make a difference to the viewpoint of others, or add to their understanding about the world.
