Issue Range shifts, invasive species and ocean acidification disrupting food chains

Summary

Over the longer term, the report expects rising temperatures could drive species out of the habitats they naturally occupy. Invasive non-native species could then gain ground at the expense of native wildlife. At the same time, ocean acidification and algal blooms could unsettle marine food chains, causing losses of food and livelihoods. The report warns that this could lead to more migration and deeper poverty. It explains that invasive species deepen biodiversity loss because they outcompete native wildlife and carry disease into new areas. Overfishing is also eroding livelihoods and food supplies for coastal communities, both in the UK and elsewhere.
