Common Mistakes to Avoid
India has plenty of water because 70% of Earth's surface is water, so there's no real water crisis.
Groundwater is infinite and gets replenished every year, so overuse is not a problem.
Canal irrigation is the most common method in India, so it must be the largest source of irrigation.
