After a bit of meditation about our relationship with the existence around, it soon starts to amaze us as to how every organism on this planet, apart from human beings, have found a balance with surrounding environment. Every organism only consumes from the nature exactly what is required to survive. Even the organisms who hibernate during winters only store enough to go through the hibernation.
Accumulation beyond what is absolutely required for co-existence with nature is absolutely a no in all plant & animal life around us. Every organism also contributes to well being of existence by performing important functions of cleaning & rejuvenating natural resources as one's limited existence allows.
This reality is in stark contrast to the great imbalance human race has created with nature. From this perspective, when I meditate on the reason for this imbalance, it is not very difficult to see.
