My post of yesterday on water leakage is a reminder that water is a key resource in our food supply. I recently came across some very interesting (and worrying) statistics:
Today, 800 million people go hungry.
By 2050 the world's population may have reached 10 billion.
About 30% of all our food ends up rotting on farms or in landfill.
In the UK households waste 20% of groceries simply because of confusion over labels ("best before" does not mean "do not eat after").
It takes over 30 times a much water to produce 1kg of beef as it does to produce the same weight of potatoes.
It takes 25kg of feed to produce 1kg of beef but just 2kg for 1kg of crickets. Let's eat more crickets.
There are some 50,000 edible plants in the world but just 3 (wheat, maize, rice) account for 60% of the world's calorie intake.
There are over 100,000 species of algae but we cultivate just 20 for food.
Vertical farming can use 95% less water than conventional cultivation.
Food for thought.
