Similarly, the search for solutions to the world's grave environmental and developmental problems must go beyond technical-utilitarian proposals and address the underlying causes of the crisis. Genuine solutions, in the Bah ' view, will require a globally accepted vision for the future, based on unity and willing cooperation among the nations, races, creeds, and classes of the human family. Commitment to a higher moral standard, equality between the sexes, and the development of consultative skills for the effective functioning of groups at all levels of society will be essential. The Bah ' International Community is, therefore, pleased to offer the following elements for possible inclusion in such a declaration of principles. In order to reorient individuals and societies toward a sustainable future, we must recognize the following.
Unity is essential if diverse peoples are to work toward a common future.
The Earth Charter might well identify those aspects of unity which are prerequisites for the achievement of sustainable development. The unrestrained exploitation of natural resources is merely a symptom of an overall sickness of the human spirit. Material development must serve not only the body, but the mind and spirit as well. The changes required to reorient the world toward a sustainable future imply degrees of sacrifice, social integration, selfless action, and unity of purpose rarely achieved in human history. These qualities have reached their highest degree of development through the power of religion.
