Explanation:
A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs. This may be behind the dinosaurs' demise. Common sparrows are going extinct because of mindless urbanisation. They are losing not just their natural habitats but also the essential human touch they need and thrive upon. The indifference caused by a lack of emotional connect has pushed these birds to the edge of extinction.
