We are different in many aspects, including our appearance, personality, interests. Our home planet Earth is full of various kinds of flowers, fruits, animals. Our equipment, utensils, playthings, and movies we see vary. The world deprived of such variety is monotonous and intolerable. The obvious diversity all around the world gives beauty to our life.

The idea for the current book is taken from the field of biodiversity, which refers to the various kinds of living species, including plants, animals, fungi, and bacteria on our home planet earth. Scientists estimate that the total number of species of land plants should be more than 450,000. There are about two million species of animals, most of which are insects. Scientists declare that more than two million marine species exist. It is noteworthy that the earth’s biodiversity is so rich that many species on land and the seas have yet to be discovered.

We Are Different shows the importance and necessity of this variety with attractive pictures. Unfortunately, the magical earth’s biodiversity is seriously at risk because of harmful activities human. I hope one day all humans learn to respect living organisms and have a concern about the environment, ecosystem, and biodiversity.
