There are no conditions for their existence, and therefore they disappear like dinosaurs became extinct. Each historical period has its own birds, animals, and people. And just as our life is assigned a certain period, so the species of animals exist for a limited time.
Therefore we need to regret only one thing when we leave this world: Have we used the life given to us correctly? You need to agree with what is given to you and try to do everything that is still possible to do.
