To mention a few: materialism, planned obsolescence, and a desire for large families. Participation of PAMB in protected Materialism presumes that man’s fundamental needs are material. With it, area management 4 individual identity becomes equated with the accumulation of material possessions. The drive to accumulate wealth originated in the belief that man is separate from nature and its master. This attitude has led to the abuse of The mangroves of natural systems and resources.

Solid wastes: Their In the face of a wide reassessment of values, the pursuit of materialism has potential hazard begun to recede. One alternative to materialism is the so-called voluntary simplicity.
