As of today, more than 900 species are extinct, and about 17,000 are threatened to be extinct. Yet, many people are not aware of the fact that certain species of animals have disappeared on the earth. Hence, we created a campaign not only to arouse public interest in this issue but also to commemorate the disappeared ones. We selected twelve human-induced extinct animals to cherish one by one, every month. We wanted to become the voices of them as our campaign name suggests. We hope the campaign raise awareness of people so that endangered animals can be prevented from extinction.
