What is the future of the next 10 or 20 years on earth? As a precognitive I can see a whole lot of people dying from Starvation and Wars

Does this have to happen?

In some ways nothing "has to happen" but trying to get something else to happen that you might prefer worldwide will take so much energy, love and patience and work that it is presently unlikely to happen.

However, that being said, almost anything can and will happen both good and bad around all this in the coming years.

The biggest factor here is not Trump or Putin or Xi.

The biggest factor is Global Climate changes and people moving around the world to try to survive this as food prices go through the roof from ruined crops worldwide as the winds continue to increase in velocity over the years blowing away crops and sometimes trees as well.

The flooding will likely continue haphazardly when we least expect it worldwide while other areas might have severe droughts. So, both flooding away communities some places and droughts other places will become much more normal.

And both of these things will prevent people growing enough food to live at a price people can afford to pay worldwide. 

So, mass starvation worldwide is something we all need to prepare for now.

How do you prepare for this?

By Buying or renting land where you have a good and relatively inexpensive water source so you can grow your own food.

I know people that have only 2 1/2 acres of land who are able to grow 70% of the food they eat and have done this since the 1970s. So, this can easily be done if you have access to land and water cheap enough to do this too.
