1) There is a new technology to desalinate water using solar enery. Not yet scaled to industrial size, but here's hoping...

2) I donate to a group "Trees for the Future" as I also believe that global deforestation is a main reason for global droughts. Here is the group's annual report. Small group, outsized results.
