Many people believe that the ancient Mayans self destructed by their own practices.  They figuratively killed themselves by going head-on with progress but never realized to themselves that by doing so, they were slowly decaying and destroying their civilization.  The Maya built a lot of structures to cater to their increasing populace.  They cut down trees so that they can use those trees to burn limestone and use the burnt limestone to build pyramids, houses and other structures.

By looking back at what transpired with Mayan civilization, we can witness history repeating itself especially in today’s world.  We are also the same mistakes the ancient Mayans have made.  Another thing that can point out that history repeats itself is the climate change that the ancient Mayans experienced during their heyday.  We can consider them the “pioneers of everything” until around 6^th century A.D.  By 900 A.D., after which, most of the great stone cities of the ancient Mayans were totally abandoned.
