Claim: The businesses, communities, forest and natural resources and our personal lives do not need a sustainable management.
Evidence: Our personal lives also need to be managed sustainably. 
Forest and natural resources need to have sustainable management if they are to be able to be continually used by our generation and future generations. 
For example, the practices of a business should be sustainable if they wish to stay in businesses, because if the business is unsustainable, then by the definition of sustainability they will cease to be able to be in competition. Communities are in a need of sustainable management, because if the community is to prosper, then the management must be sustainable.
