We're Oversalting Our Food, And It's Not What You Think

Dry regions produce a third of global food but face challenges due to soil salinity. Salt accumulates in dry soils, affecting crops by blocking water uptake. Historical examples like Mesopotamia show the impact of salty soils. Current solutions include flushing soils with water and planting deep-rooted vegetation to manage water tables and salt levels. These methods help preserve farmland and maintain food production.
