Sustainability is one of the critical issues in the present arena of human activities on the earth. One of the easiest and effective tools of sustainability is the selection of the native genetic resources for food and agriculture purposes. I hereby give the example of this type of native Acacia tree, which does not need any water and special care but remains fresh and happy. Also, it provides the home with the various and diverse life of insects and rodents etc. I hereby suggest using the native genetic resources as a tool to sustain life on the earth.
