The Global Water Crisis(全球用水危机)
全球水资源危机与解决方案——一篇演讲稿

全球水资源危机与解决方案——一篇演讲稿!我非常荣幸能够有机会在此向各位介绍全球水资源危机与解决方案。
我们都知道,水是人类生存的必需品,但由于气候变化、污染和人口增长等地球问题的影响,在许多地方,水变得越来越短缺。
这就导致了全球水资源危机。
据世界自然基金会的数据,全球超过两亿人无法获得安全的饮用水,800万儿童死亡于水传播的疾病,而在全球,每年有超过3000万人死于缺水或水质不佳的健康问题。
不仅如此,全球水资源的分配也不公平,许多发展中国家面临着严重的水资源缺乏问题,对于这些国家来说,水不仅是生命之源,更是经济和社会稳定的支撑和发展的基础。
所以,我们必须找到解决全球水资源危机的方法。
这里我提出几点:需要提高人们对于节水的认识。
节约用水,就是在不影响正常生活和生产的情况下,尽可能地减少水资源的使用和浪费。
就像我们常说的“用水如金”,我们需要从每一个身边的人做起,真正体悟到节约用水的必要性。
需要加大水资源保护的力度。
水的保护就是减少受污染的水和减少水资源的消耗。
现在技术越来越先进,可以采取更加高效的保护手段来维护水的质量和数量,比如,对于现有污染源们可以采取技术手段进行污染物治理和再生利用,对于水的消耗方面,可以采用节约用水技术,以及研发可持续利用的水资源技术。
需要加强国际水资源的协作。
国际社会需要建立公平、合理的国际水资源利用制度,促进全球经济和社会发展的可持续性,为人类提供可持续发展的温馨家园。
从这三个方面,我们可以想到许多具体的措施。
比如大力宣传节约用水的重要性,更加完善的技术体系,以及促进国际协作等等。
相信这些措施的实施将会在全球水资源危机中发挥重大作用。
我想再次强调:水不仅是人类的生命之源,更是支撑人类经济、社会稳定和发展的基础,我们每个人都应该为保护水资源、保护地球做出自己的贡献。
谢谢!。

The Global Water Crisis
As we all know that there are more and more environmental events in our world . However , one of the most serious problems is the global water crisis.
Water is vital to the survival of all known life forms. Water crisis is the state of the world’s water resources in relation to human demand. Global scarcity of usable water and water pollution are the major aspects of water crisis. A lot of people around the world do not have access to clean potable water, and the numbers are growing.
Around the world, 1.1 billion people are living without clean drinking water; another 2.6 billion people do not have proper sanitation, this results to death all over due to water borne diseases.
We see water all around us, yes 71% of the Earth’s s urface is covered with water, but we have to understand that only a percentage of that is fit for consumption. The large water composition of our planet doesn’t mean that we have an infinite supply of useable water. By simple observation, a huge portion of the Earth’s water is salty, or locked up in ice and glaciers.
The Earth although abundant with water has a limited supply of fresh water. Oceans may be deemed as available water but the energy needed to convert salt water to fresh water is restrictive, only a fraction of fresh water can be derived from desalination, although newer technology is helping reverse the ratio. Water which is fit for consumption constitutes only a small percentage of all the water resources, and the sad thing is that it is diminishing because of contamination and pollution.
Inadequate supply of safe water and lack of sanitation accounts for the rising number of child deaths because of diarrhea. Poor supply of water for sanitation results to deaths affecting children most especially in underdeveloped countries, such deaths are considered preventable if only we can find a way how to distribute clean water properly.
Vegetation and livestock are all dependent on freshwater resources. This is our major food source and if it is threatened, it will challenge our survival as well. Overdrafting of groundwater causes decrease in agricultural yields. Low agricultural yields and deaths in livestock are direct results of water pollution. Water pollution and overuse of
underground water resources truly harms biodiversity causing imbalance in nature
Armed conflicts arise over meager water resources resulting in displaced community due to this conflict. Regional conflicts arise in roughly 260 different river systems around the world. Existing international rules grants water rights among countries but still conflicts due to regional tensions on water supply are becoming a fight for survival, and warfare is inevitable. It is not just the scarcity of water that is causing death but the conflict that goes with it.
The demand for fresh, safe water increases over the course of time. Everybody must take their part in conserving water. The global water crisis will never go away if we don’t take an active part in providing our very own share. Each of us must think twice every time we turn that faucet.。
