Abstract
About one‐quarter million people daily are added to the 5.3 billion that already exist on earth. This rapidly growing population is increasing the pressures on the global environment, threatening its ability to supply itself with adequate amounts of food, water, and fuel and with a quality environment. The growing use of fossil fuels, deforestation, and other human activities is increasing CO2 and other greenhouse gases in the atmosphere. The projected global warming is expected to increase temperatures generally and reduce rainfall and water availability to crops, especially in the temperate regions. The negative effects of global warming on agriculture can be offset to some degree by soil and water conservation, altering crop varieties, improving pest control technologies, implementing crop rotations, and employing other sound ecological technologies for resource use in agriculture.
