Lets teach(genetically modify) Algae to make oil. Let's build dikes around Bangledesh and Florida for global warming induced rising sea waters. It is too late to stop Global warming so let's prepare for it. Let's improve water desalination technology. Let's create better technology for electric car batteries.
Well said!
