hunting or harvesting natural populations at a rate that exceeds their ability to replenish their numbers

sustainable development

human activities that meet present needs for a reasonable quality of life without exceeding nature’s limits and without compromising the ability of future generations to meet their needs

all species classified as critically endangered, endangered, or vulnerable
