Many have reviewed the popular Jared Diamond's book, Guns, Germs and Steel. It is a good book that talks about the history of humankind and provides broad explanations for the direction in which different parts of the world have evolved.
There is a slightly less popular but equally engaging book by the same author called Collapse. Collapse is a effort to understand the reasons why certain societies of the world collapsed. Jared says that there are five major causes why societies collapse. They are,
- Damage that people inadvertently inflict on their environment
- Natural climate change
- Hostile Neighbors
- Decreased support by friendly neighbors
- Society's responses to its problems
It pains me to hear about people eating mud to survive in our times. Human population is straining the resources of the earth. If Gaia hypothesis is true, then earth will just realign itself to a newer equilibrium. There are multiple causes at play that has lead to this food crisis, but it is our responses to these problems that will define our future. What am I doing about it ? For starters, I am reducing my consumption to only what I really need. Stop wasting resources that are at my disposal.
