Thoughts and Reflections: Irrigation

             
       When irragation was invented, it helped a lot of farmers to raise more food which led to high productivity and trades. It also allows population to increase. building irrigation was hard back then because there was no power, so people then used hand tools to build great irrigation canals. I think people back then were amazing, creative and smart because building irrigation canals is not easy without any power.
