Soil degradation .4
Problem: Overgrazing, monoculture planting, erosion, soil compaction, overexposure to pollutants, land-use conversion - there's a long list of ways that soils are being damaged. About 12 million hectares of farmland a year get seriously degraded, according to UN estimates.
Solutions: A wide range of soil conservation and restoration techniques exist, from no-till agriculture to crop rotation to water-retention through terrace-building. Given that food security depends on keeping soils in good condition, we're likely master this challenge in the long run. Whether this will be done in a way equitable to all people around the globe, remains an open question.
