Biodiversity, legacy of ancient Noah 1

Since the time of the destruction of dinosaurs 65 million years ago, biodiversity is more serious than ever. The hot focus of the problem lies in tropical forests, of which 10 million species live on Earth and 50-90% in tropical forests. However, they limit 17 million hectares a year and at this rate, scientists believe that 20% of all species can be destroyed in the next 30 years.
