The document proposes three models to promote sustainable environment management during the COVID-19 pandemic: 1) a "Goodbye Methane" model to convert agricultural and household waste into biogas and biofuel using a mobile app, 2) a community forestry and vocational training model to employ locals and promote ecotourism, and 3) a government-supported loan program for green entrepreneurship. The models address issues of methane emissions, unemployment, and economic stability while following health protocols. Feasibility analyses and examples demonstrate how the models could be implemented through cooperation between various stakeholders.
