A piece of land at a hillside will be developed as a residential area. As a housing developer, suggest steps on the conservation and restoration of the ecosystem in that area. Give some details.
Suggestion 1: The housing area is built far away from the hillside. This ensures the safety of residents and houses.
Suggestion 2: Replant all trees that were cut so that the roots of the trees can grip the soil. This maintains the hillside stability and avoids landslide.
Suggestion 3: Plant grass to cover the Earth. This avoids heavy rain from causing soil erosion and rain water to drain soil and mud which causes mud flood
Four important components of food security:
food availability (ketersediaan)
