The time to protect and restore our environment is long over due ..I fear it may be too little too late to save it unless drastic measures are taken! ..man is a very polluting animal and when it comes to profit nothing can stand in the way of it. Prosperity really does bring pollution ..there is just too much drain on the earth’s resources ..the more people the more the demand for resources ..seems to me that there is just too many people in the world and societies all over the world should start practicing responsible family planning ..there’s just too many kids being born to irresponsible people who don’t give a damn for the welfare of the unwanted children or the environment ..people have to be taught how to be responsible parents for many reasons not just because of the environment. Less people on earth will bring a better quality of life rather than on quantity ..the less the demand the less turmoil and strife in the world ..and the cleaner the environment will be ..it’s just common sense.

Sorry, We are about 30 years too late, and that is before you calculate in the population growth of the last 30 years

I remember a great lecture in architectural school about how less than 1 percent of Earth’s water is potable and that really struck me on how valuable our clean water is and to treat it accordingly.

..and that’s when the rich will grab it, horde it and make huge profits off the precious resource!

@Doug A. I heard that Nestle Corp has been doing it already by draining the Great Lakes slowly and selling it off to other countries. Do not know if this is true, but saw it on a Jesse Ventura show.

There are many methods of getting potable water however. Desalination plants provide access to the salt water, and filtration plants to the non-potable freshwater.
But yes, it is essential to keep water clean still.

Fresh water is a valuable resource. If you want to actually find that value and optimize its distribution, then you must seek property in all things and allow the market to function. If you wish to continue the sub-optimal preservation and distribution that exists now, then keep applying the same state and collective solutions that violate rights and destroy prices. The state is not the answer.

Yield is 1 gallon per 3 gallons wasted witch reverse osmosis. Cool idea with the salt application. The big thing is eliminating waste! I’m with this!

One half of all fertilizers applied to crops, lawns and golf courses is taken up by plants and the other half ends up in our ground and surface waters. Over fertilizing increases profits for agribusiness, but is bad for all the rest of us. Acidic waste water generated by industry is most often neutralized using sodium hydroxide which increases salinity in the waste water.

Is there salt in the fertilizer and sand that is put on the road?
The Muckler
November 7, 2019 at 7:53 pm
Salt is the least of our worries…..and she misses the biggest salt contributers : US farmers and their fertilizers. She’s lobbying for funds for the firms she represents….not the environment

None of this makes a 100% pure product. This amount of salt alone is not a problem but polution is. I add salt to fresh water this helps fish survival rates. And drought increases salt naturally in rivers.

I am sorry, but she’s wrong! The salt is not the problem.

@Elan the problem is when people throw garbage and plastics in the rivers.

This is dumb just reintroduce fresh water mussels they clarify the river water! And keep it healthy….what a stupid woman obvs hasn’t got her heart in the right place and intent is probs to make money then piss off leaving the rivers with problems created by her and her research…Mother Nature already has the solution dear, you’re just blind and ignorant.
