Resources are Scarce! Resources are scarce and not distributed properly. Generally because of few reasons- Human Security & Conflict Pressure on Natural Resources Mismanagement by State, Business & Local Community Legal Issues

Cont… Human Security & Conflict: Conflict on Land, Natural resources extractions, natural degradation Pressure on Natural Resources: Globalization, Development, and Environment, Demographic Factors, Pollution, and Environmental Degradation, Inter-dependence of Water, Forests, and Minerals, Use of Water in Other Commodities, Climate Change

Cont.. Mismanagement by State, Business & Local Community: Basically caused by government, city corporation, industries, municipalities and households Legal Issues: Caused by inter governmental issues or global legal issues

Interrogated approaches can be taken… The problems can be solved through- Strengthening Regional and Global Cooperation Learning from Best Practices Promoting Integrative Policies Applying Science and Technology Changing Mindsets and Behavior

You have to change your behavior in some of your daily activity – Do not use too much electricity in day time, do not turn on lights unnecessary, turn off your lights when you will go outside your room Try to do gardening in your home, plant trees. Manage your household solid waste, try to recycle your waste, avoid using polythins and plastics. Dump your waste in proper places. Turn of you stoves when you have done your cooking. Do not use vehicle un-necessarily where there is a walking distance Try to use cycles, bus as vehicle to reduce emissions. Know the causes and remedies of environmental pollution. Let other people know about your environmental concern through sharing information with family and peers.
