2 Quick good news snippets:
1. China has replanted an area the size of Belgium with trees, and by 2020 should have replanted an area the size of France. I’ll say that again; an area the size of France!
2. Rail may not be the best way to get 3rd world economies moving. Rail involves serious infrastructure and relies on trucking and local transport either end. Instead, some are starting to recommend airships that can fly goods and people almost door to door without thousands of kilometres of railway line required! It’s cheaper as well.
