Video: Shallow-water mining is not the answer to deep-sea mining
Because of the environmental and economic concerns associated with mining mineral deposits on the deep seabed, some companies and countries are considering shallow-water mining instead. A recent open-access paper raises concerns about viewing shallow-water mining as an eco-alternative to deep-sea mining.

Severe flooding can deteriorate the soil and make large-scale landslides and embankment breaches more likely during future heavy rains. Cement treatment can fortify soils against disaggregation. A recent investigation of cement-treated soil samples from a 22-year field test confirmed such soils maintain their strength long term.
