Manna from Heaven - How to feed the World?

According to the Bible God made the world & everything in it in 7 days. Presumably when he did that there was balance & the complex interrelated systems & biosphere worked effectively. Over the millennia we, who were created thinking, sentient, beings, have managed to wreak havoc & destruction on this beautiful planet. 

Not only that, we have multiplied to the point where we are using up all the natural resources at an unsustainable rate. Look at the Population Matters website, the bare statistics are there in easily assimilatable form.

That world population needs to be fed. Currently David Beasley, head of the U.N. World Food Program, said its latest analysis shows that "a record 345 million acutely hungry people are marching to the brink of starvation" — a 25% increase from 276 million at the start of 2022 before Russia invaded Ukraine on Feb. 24. Globally, hunger levels are alarmingly high. According to the 2022 State of Food Insecurity in the World (SOFI) report, the number of people affected by hunger rose in 2021 to 828 million, an increase of about 46 million since 2020 and 150 million since 2019, before the outbreak of the COVID-19 pandemic.The inequality of access to good, nourishing food is shocking.

Add to this mix that there is increasing probability of acute water shortages & any intelligent person can see that we are marching towards a massive problem. The combination of both food & water shortages is a recipe for disaster.

We need to change our behaviour before it's too late. Food & water are so basic to life that countries need to be as self sufficient & sustainable as possible. The UK is an island. Importing food from around the world isn't sustainable any more. The world has the capacity to produce enough food for everyone & make sure that it is shared equitably. But that will need political will to make difficult decisions as well as individuals in the world of the "haves" to share equitably with the world of the "have nots". Otherwise there will be civil unrest on a huge scale.

Unfortunately I don't believe in "manna from heaven". We created this mess. We have to sort it out & there isn't much time.
