The extinction of dinosaurs can be partly attributed to human activities as well as natural disasters such volcanic eruption, earthquake etc. Humans has been endangering the life of animals in the wild long time before now. They managed to encroached on their territories thus making their habits inhabitable for them. Owing to this reason some of the big animals like dinosaurs were unable to tolerate the threat on their habitats and what they did was to flee to places where natural disaster became inevitable.

Dinosaur extinction is also known as the Cretaceous-Paleogene extinction event. Until now, the extinction of these species still comes as a mystery to scientists. However, most hypothesis point to climate change as being the dominant explanation. Remember that during these times the earth is still not that habitable for species to survive. Coupled with volcanic eruptions, and asteroid and meteorite bombardment, the atmosphere becomes occupied with various greenhouse gases intoxicating not only dinosaurs but all other species on earth. Plants, which are the major source of food, wilted and died, especially those that were not able to adapt to the extreme conditions. Those that were able to evolve or mutate may perhaps had significant decline in productivity. When the food chain collapse, it's effect accumulates from the primary up to the apex consumer. Thus, food shortage amongst species also become apparent.
