home for us and for those who are to come. The failures that we need to correct arise both from poverty and from the short-sighted way in which we have often pursued prosperity. Many parts of the vicious downward spiral: poor people are forced to overuse world are caught in (5)ª environmental resources to survive from day to day, and their impoverishment of their environment further impoverishes them, making their survival even more difficult and uncertain. The prosperity attained in some parts of the world is often unstable, as it has been secured through farming, forestry, and industrial practices that bring profit and progress only over the short term.

Food production is a driver of the climate crisis and a (24) of it. ( 25 ) the food system will require a wide variety of actions, including increasing crop diversity, delivering climate (26) to farmers around the world, expanding conservation programs and offering growers insurance that pays out when an index such as rain or wind speed falls above or below a fixed limit. The Biden administration is supporting research into "climate-smart" agriculture, an approach to managing cropland, forest, fisheries and cattle that attempts to address the intersecting challenges of the climate crisis and food ( 27 ). In May, the UN secretary general, António Guterres, said that climate-related disasters and extreme weather were a driver of global hunger and that 1.7 billion people ( 28 ) by the climate crisis over the last decade. Experts say (29) action is taken, we can expect to see increased food prices, decreased availability and conflict over water, which will primarily affect poorer countries and low-income Americans, (30) everything from school lunches to food aid programs. © Copyright Guardian News & Media Ltd 2023 (1) sriracha (2) drought かんばつ 世界中で人気のチリソース
