not including the oceans. Can you unpack this stat? DB: Essentially 43%of the seven continents is devoted now to feeding humanity.
and then letting it run off into the ocean. And then it goes into the cycle
like finding way to desalinate sea water cheaply and easily. If we did that we would not have to worry about depleting aquifers
because it would take us a very long time to deplete all the water in the oceans.
The good news is that we â â¢ve been dealing with sea level rise and weird weather for most of human history.
and can build sea walls or shift populations. The majority of people driving climate change those are the rich will adapt fine, no problem.
There are projects testing out the possibility of seeding the ocean with iron; this is a fertilization scheme.
Ocean plankton are one of the biggest CO2 sucks on the planet, and if you fertilize them there might be more blooms.
Unlike corn or even sugar ethanol, halophyte algae (algae that grow in saltwater) do not compete with food stocks for freshwater. oewhen the cost of pumping ocean water into so-called wasteland regions such as the Sahara
halophyte algae farmers could use solar-powered pumps to move water up from sea level or even up from underground aquifers such as the Nubian sandstone aquifer system that sits beneath desolate regions of Libya, Chad, and Sudan.
Tidal-current turbines and tidal-stream turbines tapping the power of sea systems like the Gulf stream could provide energy for power-hungry states such as Florida.
The Center of Excellence in Ocean Energy Technology at Florida Atlantic University The Issue: Hunger The earth population is projected to increase by 2. 5 billion people in the next four decades,
Individuals (mostly women and children) are forced often to trek long distances to lakes ponds, or public water pumps in other villages,
