1. 珍惜水资源
水对于我们的生活和国家经济的发展是不可缺少的。水经常被比作万物之源和工农业的血液。没有了水，万物将不能存活，我们的世界也就变成了死亡的沙漠。
我们居住的世界现在正面临着严重的淡水缺乏。根据官方数据，世界上超过17亿人口喝不到足够的纯净水，且平均每天都有2.5万人死于缺水而导致的疾病。
所以，我们所有人都应该积极保护水资源——这是我们为了子孙后代的利益而应该履行的责任。

2.环境保护
地球气候变化已经带来了一种新的自然灾害，也给发展中的复杂的城市系统人为地带来了一种潜在的隐患。同时，自从大量化工产品在利益的驱使下产出和使用，人们也一直被健康问题困扰着。无意中产出的有毒物质被堆积在自然环境中。因此，我们需要从不同观点中发现对策以便保护城市环境，使它免受灾难或承受环境风险。所以我们将发展并提高一种新的风险避免系统以及灾难避免系统来保护并改进城市环境，在那里人们在生活中感觉轻松和平安。
