It’s one third that is very rich and two thirds that are very poor.People in the rich countries don’t realize the great difference between them and those in the poorer countries. A very simple example is that a dog or a cat in North America eats better than a child in the poorer countries. A fisherman in South America may be catching fish which is made into pet food, and his own children are not getting enough to eat for their bodies to develop properly.Although a lot of the world’s natural resources like oil come from these poorer countries, people in the richer countries are probably using sixty times as much of these resources as a person in Asia or Africa. And it’s the richer countries that decide what kind of prices they are ready to pay for these resources.

1 2 3 456（78港珠澳大桥被誉为桥梁界“珠穆朗玛峰”，还被英国《卫报》誉为“现代世界七大奇迹”之一，这座从设计到建设完工前后历时14年的“超级”跨海大桥创下了多项世界之最。

港珠澳大桥全长55公里，包括三座通航桥、一条海底隧道、四座人工岛及连接桥隧、深浅水区非通航孔连续梁式桥和港珠澳三地陆路联络线。

据了解，港珠澳大桥是目前世界最长的跨海大桥，还是目前世界上综合难度最大的跨海大桥。

同时，港珠澳大桥有15公里为全钢结构钢箱梁，是目前世界最长钢铁大桥。

在海底隧道方面，港珠澳大桥同样创下了多项世界之最，港珠澳大桥海底沉管隧道全长6．7公里，是世界上最长的海底隧道，港珠澳大桥海底隧道最深处在海底48米，也是世界上最深的海底隧道同时，港珠澳大桥还拥有最大的沉管隧道，其沉管隧道标准管节，每一节长180米，排水量超过75000吨。

在工程建设上，港珠澳大桥采用了世界上首创的深插式钢圆筒快速成岛技术，用120个巨型钢筒直接固定在海床上插入到海底，然后在中间填土形成人工岛。

每个钢圆简的直径22.5米，几乎和篮球场一样大，高度55米，相当于18层楼的高度。

其深水无人对接的公路沉管隧道同样堪称世界最大难度，沉管在海平面以下13米至48米不等的海底无人对接，对接误差必须控制在2厘米以内。

大桥靠什么能使用120年？记者了解到，按照施工标准和建筑材料质量“就高不就低”的准备，港珠澳大桥设计使用寿命能达到120年，而这也打破了国内跨海大桥通常的百年惯例。

港珠澳大桥管理局总工程师苏权科接受媒体采访时表示，在国家科技支撑计划的引领下，中国科研人员依靠1986年以来湛江地区累积形成的海洋水文数据攻克了大量技术难题，创造性地提出了港珠澳模型等一整套具有中国特色、世界水平的海洋防腐抗震技术措施，最终保障了相关指标的达成，制定了120年使用寿命的设计标准。

据了解，港珠澳大桥具备抗16级台风、8级地震的能力据港珠澳大桥管理局介绍，当强台风“山竹”路过港珠澳大桥时，监控信息显示大桥安全、正常，当时桥面测到“山竹”的瞬时最大风速是每秒55米相当于16级台风风速水平，此时港珠澳大桥的索力、位移、震动监测都还在设计范围内港珠澳大桥经历住了极端天气的考验，而这已是继“天鸽”“帕卡之后，港珠澳大桥第三次迎来强台风的侵袭。
