To avoid desertification, we reforest all plateaus and forest basins by planting more trees to replace cut and fallen trees.

Establishment of “green institution” policies in every learning institution will add value to the environment. “Greeneye-habitat,” where people are taught the significance of the habitat and the use of renewable energy instead of wood and charcoal, is important.

Governments adopt proper settlement policies. Watercourses be protected and people settle nearby riverbanks. Proper waste disposal such as burying wastes into the soil and recycling the waste to reuse it as fertilizers and other useful products be employed.
