Answer:
Equitable distribution of resources is necessary so that every organism gets its share of resources to meet the basic needs of its life-like water, food, and shelter.
The forces working against an equitable distribution of our resources are uneven distribution of resources geographically, the greed of certain humans, and the socio-economic gap between the rich and the poor.
