Resources are anything available in the environment that satisfy human needs. They must be technologically accessible, culturally acceptable, and economically feasible. Resources are classified based on their origin and exhaustibility. Planning is required for judicious use of limited resources to prevent depletion and ensure equitable distribution. Soil is an important resource that is formed over millions of years but is degraded through deforestation, overuse of fertilizers, mining, and overgrazing. Gandhi advocated conserving resources by avoiding greed and exploiting nature through sustainable production methods.
