The carrying capacity of our planet is not unlimited. The amount of production we can do to satisfy our needs is limited too as we do not have unlimited resources at a particular point of time. We are consuming more and more. We are creating huge amount of waste and polluting our planet without much consideration. WE are responsible for our problems.
Virtual or Embedded WaterÂ
It is the amount of water that is required to produce food or any other product that we use and to transport it to the market and thus essentially embedded in the item. For example, 1 kg of wheat takes around 1000 liters of water to produce. The world’s population is growing by roughly 80 million people each year. Changes in lifestyles and eating habits in recent years are requiring more water consumption per capita, putting a stress on the available fresh water resources. People in high income countries consume greater amount of virtual water than in low income countries because of different lifestyle and diet.
