In fact, modern tools like maps and satellite navigation contribute to annual savings of up to 3.5 billion liters of gasoline and more than one billion hours of travel time. As a result, farmers are better able to get their goods to market before they perish, and to build more efficient irrigation systems, which save the global agricultural industry $8-22 billion annually.
事实上，地图和卫星导航等现代化工具每年可以节约高达35亿升汽油和超过10亿小时的旅行耗时。农民们因此可以在商品腐败之前将它们运抵市场、修建更高效的灌溉系统，并因此每年为全球农业节约下80－220亿美元的开支。
