Non Governmental Organizations (NGOs), as major actors of the civil society, play a vital role in promoting conservation of natural resources, environmental protection, sustainable development, and environmental justice. While their location, size, organizational forms, scope, and impacts can vary widely, all of them operate towards the same mission of protecting the environment from degradation due to industrialization, uncontrolled development, depletion of bio-diversity, and over consumption of natural resources. Although environmental conservation has been a part of civil society involvement throughout history, environmental NGOs have emerged as a major sub-sector of the NGO sector during the past three decades. Their impacts are among the most visible contributions to humanity by the global NGO sector.
