Signal Crop diversity shrank 75% in the 20th century

Summary

The report finds food security under threat as pollinators and pest-controlling species decline and agricultural biodiversity weakens. Crop diversity dropped by 75% during the twentieth century. Because around 69% of UK land is farmed, the loss of beneficial invertebrates could translate into lower crop yields. The report is particularly concerned about the effect on nutrient-rich fruit and vegetables. Overfishing is also eroding livelihoods and food supplies for coastal communities, both in the UK and elsewhere. Over the longer term, the report expects ocean acidification and algal blooms could disrupt marine food chains and cause losses of food and income.
