Throughout history, human have considered lions the biggest predators in the world. However, the biggest predator for lions is human. During 1960, there were 450,000 lions in the world, but the recent study shows that there are fewer 20,000.

The reason for the declining is because of hunting. This activity has largely damaged the population of the wild cats and influenced the balance between lions and other cattle cultures. For example, if we killed the lead male lion in the lion group, it can have a drastic effect to the whole group.

After the former lead male lion got killed, a new male lion will come into the group and possibly kill all the cubs and some of the female lion. Lions are the most vital center point in many ecosystems. If the number of lions keeps decreasing, our whole environment will eventually collapse, because it will affect the water system, the prey’s migration, and the cattle will overgraze and destroy the vegetation. So now people associate with National Geographic to found the Big Cat Initiative in order to prevent the illegal hunt of the big cat and to maintain our ecosystem.
