green infrastructure

A network of decentralized storm water management practices like green roofs, trees, rain gardens and permeable pavement that can capture and infiltrate rain where it falls thus reducing storm water runoff and improving the health of surrounding waterways These practices deliver multiple ecological, economic and social benefits or services that can have a positive impact on energy consumption, air quality, carbon reduction and sequestration, & more

The cost of reducing extinction risk of threatened plant and animal species is around $3.41 - $4.76 billion annually. Cost of protecting and effectively managing all terrestrial sites of global avian would cost about $65.1 billion then the cost of protecting global network sites for nature is around $76.1 billion. Compared to the $6.6 trillion we would have to pay without being protected

Compare the costs of biodiversity conservation to the net value of ecosystem services that are lost when they are not protected, according to McCarthy et al. 2012

Clean Air Act of 1970

Comprehensive federal law that regulates air emissions from stationary/mobile sources, authorizes EPA to establish NAAQS to protects public health and public welfare to regulate emissions of hazardous air pollutants Goals: set and achieve NAAQS in every state by 1975 in order to address public health and welfare risks posed by certain widespread air pollutants Failed to meet deadlines

· Home gardens are mainly subsistent so they're primary function is food production with the diversified planting and harvesting which provides people with firewood, fodder and timber and sustains soil productivity through nutrient recycling and reduces soil erosion. So everything is localized and the gardens can supply ¼ of the fuelwood requirements for a family thus decreasing deforestation and carbon emissions since consumption patterns are sustainable
