There are many animals out there that are important to us and our environment and need to be helped. The population in the western Pacific, however, is critically endangered. Monoculture , the agricultural method of growing a single crop , can also reduce genetic variation. The Mission Blue Butterfly is one of the dozen insects on the endangered species list. Development for housing, industry , and agriculture reduces the habitat of native organisms. Non-native plants crowded the cyanea out of its habitat, and non-native animals such as pigs, rats, and slugs ate its fruit more quickly than it could reproduce. Or does it?

Another significant challenge to conservation is the international trade in rare species. This species is a dogfight to prevail and live on as a species, but are terribly losing.

People do not really care that somewhere, far away from their comfortable homes, species of animals and plants are disappearing from our planet forever.
