Waste water speaks for itself it is water that is overwhelmed with wast. It can and will be contaminated with everything from ecoli to hepatitis to lead. Treating waster water keeps us all safe. If a waste water treatment facility is not accesable then filtration with sand and charcole along with boiling the water will help with the removal of deadly chemicals and harmful waste. without treating waste water, if you were to drink it.....(unless your indestructable) you will become very very very ill and it will be very very very fatal.
People treat a girl in Iran mostly according to the religion of Iran which defines most of its culture. Non-Iranians have difficulty understanding why woman drivers have so many restrictions placed upon them, but again the policies have to do with the country's religion.

Pros My first reason is that we canadians waste water only 57 percent of Canadian communities treat the waste, so why not gice some water to the country that actually use the water properly and not waste it, because only 9percent of the world is Fresh. Cons We should use our own water there are a lot of people who still doesn't get water.
U should treat them very generously like the US did with Germany or Iran
