I was trying to think what the future of the world with Global Climate changes will look like:

There is a book called: "Nomad Century" by Gaia Vince which my wife was showing me that she bought which likely will go into more detail than what I'm writing here.

But, as I think about it now what I'm seeing is a stark difference between the Have and Have not nations which is sort of like Lifeboat theory in that people won't survive as much in the countries that don't have their lifeboat intact.

A Lifeboat would be enough infrastructure so people wouldn't need to panic so much about food, shelter and clothing. 

In the mid  1980s I went to India and Nepal and realized that the poorest homeless person in the U.S. could still get food and sometimes shelter and usually clothes here in the U.S.

But, at that time this just wasn't true necessarily of people without homes or jobs in India or Nepal. Over there if you didn't have any family or friends to help you dying might be your best option often because jobs were ONLY given usually to those educated some and at that time about 60% to 80% of the people had not even gone to 1st grade because there was no public government sponsored education like we have here in the U.S. at that time.

My wife and I actually paid for a year of school for two boys in Rewalsar that we met called Raju and Biju because they met us and we wanted to do something for their family at that time.

So, what we experienced likely in the 1980s (1985 and 1986) in India and Nepal will likely be the plight of most people in 3rd world nations in the present or future where the slightest calamity of weather or flooding or drought will kill off thousands of people directly or indirectly.

So, the point is that the homeless people in the U.S. are much much much richer in reality than the homeless of most people in 3rd world nations right now.

And in the 1980s when I was there this difference in wealth in a real sense was often the difference between life (in the U.S.) and death in a 3rd world country.

So, it makes perfect sense to me that 10,000 people a day are trying to walk over the Mexican border from Central and South America now because they don't want to die or be murdered by Gangs in their home countries.

And this is sure to get much worse over time where 100,000 people are trying to cross the border a day as things get much worse over the next 10 to 20 years in Central and South America caused by Global Warming.

For example, Bolsonaro, which was Trump's clone in Brazil has completely collapsed the water cycle in the Amazon River Basin to the point where the Rain forests are on their way towards turning into a permanent desert there. How many people will die from this alone?
