      • Although it's true that water is a renewable resource, it's often wasted.

    • Poor crop choice. As the population grows, it doesn't make sense for desert-dwellers to grow thirsty crops such as cotton or raise cattle, which requires much more water than producing an equivalent weight of wheat or potatoes.
    • Newer plants. But simply switching which crops are produced may not be enough for some regions of the world. Instead, they may need to manipulate the plants own systems' for dealing with drought to increase production.
