恐龙之丘

Many billions of years ago, dinosaurs lived peacefully and harmoniously with other animals on Earth. Like many animals, they reproduced through the union of male and female, giving birth to offspring. Typically, after a mother dinosaur laid her eggs, she would place them on the mountaintop closest to the sun, as the sun's heat could hatch the eggs into baby dinosaurs. 　　Later, Earth's environment grew increasingly harsh, and temperatures gradually dropped. When dinosaur eggs were placed on the mountaintop again, the sun could no longer provide enough heat to hatch them. Eventually, dinosaurs disappeared from the face of the Earth. 　　This is a fable about growth. Dinosaurs became extinct because they overprotected their young: the baby dinosaurs were unable to solve life's challenges on their own, ultimately leading to the destruction of the entire dinosaur species.
