Notice something in the picture? Where a red-headed spider has preyed on a green insect. You may be surprised that the size of the green insect is almost the same as that of the spider! Killing one another without weapons is quenching hunger! This is nature, one has to kill another in the forest to survive. Ever wondered? If we had to kill another human being to satisfy our hunger, there would be no food. Think? How cruel the matter would have been. People used to hide in different places for fear of their lives. How much more chaos would have been created!
