Step-by-step explanation:
Some communities in South Africa have actively contributed towards keeping their environment clean. Grassroots environmental consciousness began in the 1970s when marginalized communities opposed unsustainable commercial developments and protested the construction of large dams. The devolution of authority over natural resources to local governments also empowered communities to create and enforce regulations on the use of local resources. Efforts by communities and non-governmental organizations (NGOs) have made direct impacts on conserving endangered species and habitats.
