During the past few decades, we have been witnessing that some people including even scientists are engaging in many preservation activities on endangered animals who are living in different places in the world. While some people have critics of these programs as they consume money, others praise the actions taken to rescue the creatures from extinction. I also strongly believe that the animals who contribute to keeping the diversity of natural habitats must be preserved in terms of their role in maintaining the balanced ecosystem or their contribution to a sustained food chain and, reproducing is devoted to keeping the diversity.
