Water in the seas and oceans are pulled around the planet, and so is the water in underground aquifers.
With so much water being removed we have created an instability in the earth's crust. What water is left is sloshing about more than it would have done, and we are getting a definite wobble that is causing earth to move the pole alignments to compensate.
It is pretty awful when areas like Mexico sell their precious water to fracking and drilling companies, which leaves a country with terrible water shortages to suffer further drought to farming. This is another reason to ban Fracking and drilling and find some other way to power the world than using fossil fuels.
We really are in crisis. Intensive farming has to stop, especially where it is using water from under the ground to water great expanses of corn production that are genetically modified and use glyphosphate as weedkiller. The ground is dying.
We all have to wake up, and realise what we buy in the supermarket drives these policies of agriculture. The water that comes off the fields gets back into the groundwater we drink, so many of our water sources are now polluted.
At least with hydroponics we have a chance to produce food intensively, that doesn't involve draining aquifers.
We we also don't need to be using petrol and petrochemicals. We can do without the pollution they cause in production, and the carcinogens they create in our atmosphere from burning them in our cars and industry.
Our food security as a planet should be our foremost concern, keeping valuable resources for future use if they should be needed.
We in the west waste so much food. We need joined up thinking between food science, energy production, and waste management that will redress the imbalance that is causing our planet to try and adjust to our excesses.
