30. I know it is, but how valid is it if you don't know what the experts say about desalination?

Feb 2015

you no doubt think your opinion is a good one.

this is precisely why I posted the thread.

the people who know the most about desalination are not recommending it the way you and others are.

the people who are recommending it don't know much about the technology, it's drawbacks and limitations.

in other words, shouldn't you be learning about the topic before you decide that it's a good idea?

if you are recommending desalination without knowing what experts on the topic think of it, isn't that backwards as an approach?

why would you tell me, "let's do desalination, it's a good idea" without knowing more about the topic?

why wouldn't you say, "i should read what experts on the topic think before i discount their concerns" --why wouldn't you say that first?
