Criticality

Based on my analysis on the water pollution topic, I have face some major questions regarding this issue :

• Imagine that people live in the city with full of rubbish in the drain & river, do they feel ease or else?
• A lots of campaign organize either by Government or any NGO, but why this problem cannot be solve or reduce?
• Imagine that there are no clean water source in the world, how human can survive?
• Do we have the best way to dispose the waste materials from the industry to prevent the illegal attitude of human who simply polluted the river with the waste materials?
