Conservation efforts play a big role in reducing global biodiversity loss. While just 17% of land and 8% of oceans are under some form of designated protection, there are at least five proven conservation strategies. Marine Protected Areas protect countless species from overfishing, pollution and habitat destruction. Invasive species cost the global economy more than $423bn (£333bn) every year and are a top driver of global biodiversity loss; removing them is critical to stem biodiversity loss. As well as protecting wildlife, restoring wetlands helps prevent floods, provide fresh drinking water and reduce coastal erosion. Saving and restoring keystone species can help save a host of other species that rely on their presence. Protecting forests also is key. Natural forest regeneration, where trees are allowed to grow back spontaneously with limited human intervention, is gaining traction worldwide.
