    Something's happening at the lowest point on our planet.

    The Dead Sea, a salt lake bordered by Jordan to the east and Israel and Palestine to the west, is shrinking(缩小) at an alarming rate-----about 3.3 feet per year, according to the environmentalist group EcoPeace Middle East. And human actions are largely to blame.

    “It's not just like one country is punishing the Dead Sea; it's more like the whole area,” said photographer Mortize Kustner, who visited the area in February to work on his series “The Dying Dead Sea”.

    The Dead Sea needs water from the other natural sources surrounding it, such as the Jordan River basin. But around the 1960s, some of the water sources it relied on were diverted(使改道).Israel, for instance, built a pipeline during that time so it could supply water throughout the country.

    Mineral extraction(开采) industries are another main reason the water levels are falling, experts say. The Dead Sea's minerals have been used as medicine and can often be found in cosmetics(化妆品) and other consumer products.

    And then, of course, there's the Middle East's hot, dry climate, which makes it difficult for the lake to replenish itself.

    Last year, Israel and Jordan signed a $900 million deal in an effort to keep the Dead Sea's water levels stable(稳定). It includes building a canal from the Red Sea to the Dead Sea which would be able to not only supply water to Israel and Jordan but also to pump water into the Dead Sea.

    But for now, Kustner shows us that the Dead Sea remains very much a place of interest, with people from all over the world going there to swim in its salty waters.

    The Dead Sea, known as the Salt Sea in the language of Hebrew, is one of the saltiest bodies of water in the world. And because of what has been happening over the years, the salt is only getting saltier.

面对世界经济的复杂形势和全球性问题,任何国家都不可能独善其身。“构建人类命运共同体”这一中国方案、中国智慧、中国声音、中国版本,现在已被更多人视为圭臬。3月20日“构建人类命运共同体”重要理念首次载入联合国安理会决议,标志着这一理念已经得到联合国会员国的普遍认同,反映了国际社会的共识。这是对以往联合国及安理会决议关于“一带一路”表述的继承和发展。这一理念告诉我们,全球治理必须依靠可持续性的“国际化”发展。如果每个国家都接受和奉行这一理念,我们就将拥有一个“国际化”世界。
