Environmental activism aims to protect the natural environment from destruction or pollution. However, since 2000 environmental laws and regulations have come under increasing attack from corporate and political leaders who oppose further restrictions. As a result, nonprofit environmental groups play an important role by educating the public, organizing grassroots political pressure, and holding governments and companies accountable through legal and policy advocacy. For example, Greenpeace has pressured the Indian IT sector to reduce its carbon emissions and consider more sustainable infrastructure growth. At local levels, citizen initiatives encourage simple lifestyle changes like using less energy, water, and transportation resources to help address environmental challenges.
