As the world population grows, so does the need for water. The Worldwatch Institute says increased demands for food, energy and industry, along with climate change, could lead to water scarcity in some places. The warning comes on World Water Day, March 22nd. Worldwatch says billions of people are already facing some kind of water scarcity or shortage. Spokesperson Supriya Kumar says it's only expected to get worse as the population increases. "Over 1.2 billion are basically living in areas of physical water scarcity. And almost 1.6 billion face economic water shortage. And these are really extreme numbers. And as our population continues to grow there's just gonna be more problems. And we're going to really have to face drastic measures in order to make sure the people have access to water." Kumar says there're several types of water scarcity. The first is called "physical". "Physical water scarcity really just means that there's not enough actual water to meet all demands. Water is not distributed evenly. You know, areas in the Middle East, in Northwestern India -- very arid regions -- where there's just not enough water. And so there's not physical availability."
随着世界人口的增长,对于水的需求也随之增长。世界观察研究所称,食物、能源和工业需求的不断增加,连同气候变化一起,可能导致一些地区的水短缺。这项警告于3月22日的世界水日当天发出。 世界观察研究所称,数以亿计的人们正在面临某种水短缺问题。发言人塞博利亚•库马尔说,随着人口的增加,事情只会变得更糟。 “超过12亿的人口基本上生活在自然水匮乏的地区。还有几乎16亿人口面临经济水短缺。这些都是十分极端的数字。而我们人口的持续增长,只会带来更多的问题。我们不得不去面对严厉的措施以确保人们能够获得水。” 库马尔说,水短缺表现为几种类型。第一种被称作“自然型”。 “自然水短缺就是意味着没有足够的实际水资源来满足所有的需求。水资源并不是平均分布的。你知道的,在中东和印度的西北部这类非常干旱的地区,没有足够的水资源。所以就没有自然水的可利用性。”
