The city also is urging homeowners to tear out their lawns and plant drought resistance plants.

这个城市也敦促业主们拔光他们的草坪及耐旱植物。

In fact, the scientists are actively using the bank to breed genes for drought resistance into cultivated tomatoes — protecting food sources not only for desert rodents but for us.

事实上，科学家们正在积极地利用这个基因库为栽培的西红柿培育抗旱基因——不仅保护了沙漠啮齿动物的食物来源，也保护了我们的食物来源。

Just as we breed plants for qualities such as drought resistance or taste, the human robot breeder could guide artificial evolution to producing robots with specific qualities.

正如我们为了抗旱或味道等品质培育植物一样，人类机器人育种者可以引导人工进化来生产具有特定品质的机器人。
