Logically focusing in a solution
Being that 71% of the planet is water and 1/3 is desert does it not sense to build more desalinization plants and pipeline systems to get water from places that have it to places that have too little. This is a logical step towards reclaiming and restoring depleted water resources around the world and further more such large scale projects would put many people to work around the globe. It is the first step in dealing with these issues...
1. Lack of water
2. Desertfication
3. Sub par agriculture
There is a logical flow line which must be addressed when tackling major issues. Focusing on the micros or the macros alone will not bring about this logical flow line or lead to solving the pressing issues which face us.
