There is a longstanding controversy over water export.For proponents,exporting water is a potential economic boon.For opponents,bulk water export can turn out to be a prescription for national calamity.I have to say that the positive effects of selling water to other countries outweigh the advantages.
There is no doubt that selling water to other countries would immediately help them tackle water shortage.According to research result,Canada has one of the largest resources of water in the world.As a consequence,many people agree with that Canada should sell water to other countries.On the other hand,water export by Canada would place Canada at a disadvantage.One primary disadvantage is that Canadian Industries would have to compete for water they need at global market price.For example,Canadian companies such as hydro companies of each province need water to generate electricity for industrial and household use.In addition,water resources are integral to the beauty of Canada’s landscape.There are millions of fresh water lakes and rivers across the whole country.Tapping any water resources would involve building dams and reservoirs. These projects would definitely lead to the disruption to the surrounding ecology.The long-term environmental impact of water export would be disastrous.
