strong versus weak

I was watching this beautiful documentary on Animal Planet, which was presented by non other than David Attenborough. Nature has gifted to all its creatures its own way of defense and protection against the extreme conditions.
The documentary was on how do herbivores protect themselves from the difficult situations and from the predators. It’s seen that zebras, deer, elephants and many others herbivores are usually in a group; this helps them to fight back against the strongest predators also. A calf was chased and caught by the lion; it’s the most common sight in the savannas, but was amazing was that the entire herd chased back the lion and finally the calf was rescued.
Here it’s team work, however weak you are, in a team one can chase or face the strongest of the difficulties. Another beautiful phenomenon in nature is that even when alone these animals (deer, chital …) can run as the same speed as that of cheetahs, leopard…) to protect themselves. So if alone or in team if you are strong you win the battle.
