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.

The most widely accepted theory is that a catastrophic asteroid impact caused the extinction of non-avian dinosaurs around 66 million years ago.

Dinosaurs went extinct around 66 million years ago, likely due to a combination of a massive asteroid impact, volcanic activity, and climate change. This event caused widespread destruction of habitats and food sources, leading to the demise of many species, including the dinosaurs.

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.

Dinosaur extinct because it is an ancient animal that live in the forest and it the strongest animal in the world it extinct because they do not lay more eggs

No, I do not think that is the answer. The correct answer is between Greencrayon and Shavkat.

It was being claimed that the life of dinosaurs ended when a huge meteorite crashed Mexico's Yucatan Peninsula estimate 65 million years ago.

The dinosaurs extinct due to many reasons. It exist 96 million years ago. The volcanos, climatic changes, soil erosion , earth quake etc are the few causes.

The most widely accepted theory is that dinosaurs became extinct due to a combination of factors, including a massive asteroid impact and/or a period of global cooling that caused drastic changes in climate. This event, known as the Cretaceous-Paleogene extinction event, occurred 66 million years ago and is thought to have caused the death of up to 75% of all species, including the dinosaurs.

Evidence suggest an asteroid impact was the main culprit, volcanic eruption that cause large scale climate change my also have been involved, together with more gradual changes to Earth's climate that happens over a million of years

Dinosaursia, or the dinosaurs' business, began as a branch of the overtone taxa family, the good ones didn't care about you, so to speak. These overplayed dinosaurs probably felt left out of the riddle, because they died aandoned questions about music. It's possible that hearing with cold hard music caused their death, as they likely would have been more afraid of humans. It is a mystery we can't answer.
