  16. 16. Human Environment Human beings interact with the environment on day-to-day basis and modify it according to their needs. Due to modernisation, our needs grew, so we learned new ways to fulfil our needs. We learned to grow crops and create a system wherein transaction take place. For example: Barter system, trade and commerce, etc. Furthermore, we gather things as per demands. Example: to construct a building, we need raw materials including rocks and wood. For this, we may look to nature - we can get rocks from the mountains and wood from cutting down trees.
