               Five Amazing Forests in the World 1. Crooked Forest, Poland This grove of oddly-shaped pine trees just outside Nowe Czarnowo, West Pomerania, is a man-made wonder, but nobody is quite certain how or why. Some believe that some sort of tool or technique was used when they were planted in the 1930s so that they could be used in ship building. Others speculate that the young saplings were crushed by tanks during the Second World War and that’s what made them grow this way.

    In the cycle of life, predators always occupy an important position. They are killers. But they kill, only to 'kill' their hunger. In fact, the story of the animal kingdom is full of predators trying to catch prey, and the prey trying to outwit predators. It is the balance between the two that takes the drama of life forward. In the wild, there is no place for the weak, whether it's the predator or the prey, and only the fittest survives. The hunters keep populations healthy by weeding out the old and the sick. Of course, there are also creatures that steal the prey caught by others, like hyenas.      We have collected information about some animals for which you must know. 1 .
