Several civilizations fell in conjunction with environmental change. though the change in the external environment might not have been the only cause it certainly was a major contributor to the fall of the civilizations below (in no special order):
yes
a change in climate means that certain plants may not be able to survive. this then causes a decrease in herbivores, and then a decrease in carnivores because of the lack of food.
The climate change in Alaska is causing the amount of animal habitats to decline, forcing Alaskan hunters to find and alternate food source. The change in climate is also causing erosion damage to houses in some areas of Alaska.
Because the climate change
A species that is genetically diverse is more likely to survive in the event of a major change in it's environment, because of chance. A large swing in climate for instance, could entirely wipe out a species that was solely suited to a specific climate. However, if a portion of the species is more adaptable to a colder climate, and a portion is more adaptable to a warmer climate, even though a climate change would mean death for a large portion, a portion would be more likely to survive.
yes
climate change
Extinction, climate change, decrease or increase in animals, loss of food.
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
The decline of floodplain civilizations, such as those in Mesopotamia and Egypt, is often associated with the end of the Bronze Age around 1200 BCE. Factors contributing to their decline include climate change, political instability, invasions, and shifts in trade routes. New empires, such as the Assyrians and Persians, emerged during this period.
Change of climate,potchars,and other animals eating them.
There are various opinions as to what happened to the Indus valley civilization. Probably them most held is that climate change (disappearance of the monsoons) resulted in a migration to the east but in smaller more isolated towns.
new predators new disease new climate or environment change new competitors for food or land these all contribute to extinction
a change in climate means that certain plants may not be able to survive. this then causes a decrease in herbivores, and then a decrease in carnivores because of the lack of food.
Most likely, the end of the last ice age.
