"My long-term vision for a better rural farm policy in the future would include new wildlife corridors, agroforestry, walking paths and bike trails, natural prairies, restored wetlands, and a return to naturalized rivers. This would require returning some private land back to public land, of retiring a percentage of today's Midwestern farmland. These things would support wildlife, outdoors activities, and provide greater tourism opportunities in the Midwest. These things would protect the soil, water, and help with biodiversity compared to what it is today. They would also help to enhance the quality of life for those who are living in the Midwest and they would entice others to move there for new opportunities. And, more kids could grow up doing the outdoor activities that I did."

Land use change-for example, the conversion of natural habitats to agricultural or urban ecosystems-is widely recognized to influence the risk and emergence of zoonotic disease in humans1,2. However, whether such changes in risk are underpinned by predictable ecological changes remains unclear. It has been suggested that habitat disturbance might cause predictable changes in the local diversity and taxonomic composition of potential reservoir hosts, owing to systematic, trait-mediated differences in species resilience to human pressures3,4. Here we analyse 6,801 ecological assemblages and 376 host species worldwide, controlling for research effort, and show that land use has global and systematic effects on local zoonotic host communities. Known wildlife hosts of human-shared pathogens and parasites overall comprise a greater proportion of local species richness (18-72% higher) and total abundance (21-144% higher) in sites under substantial human use (secondary, agricultural and urban ecosystems) compared with nearby undisturbed habitats. The magnitude of this effect varies taxonomically and is strongest for rodent, bat and passerine bird zoonotic host species, which may be one factor that underpins the global importance of these taxa as zoonotic reservoirs. We further show that mammal species that harbour more pathogens overall (either human-shared or non-human-shared) are more likely to occur in human-managed ecosystems, suggesting that these trends may be mediated by ecological or life-history traits that influence both host status and tolerance to human disturbance5,6. Our results suggest that global changes in the mode and the intensity of land use are creating expanding hazardous interfaces between people, livestock and wildlife reservoirs of zoonotic disease.

In December, Antarctica lost its status as the last continent free of COVID-19 when 36 people at the Chilean Bernardo O'Higgins research station tested positive. The station's isolation from other bases and fewer researchers in the continent means the outbreak is now likely contained.

Dr. Arnott added: "Our research shows for the first time how microplastics are disrupting and causing behavioral changes among the hermit crab population. These crabs are an important part of the ecosystem, responsible for 'cleaning up' the sea through eating up decomposed sea-life and bacteria. By providing a hard, mobile surface, hermit crabs are also walking wildlife gardens. They host over 100 invertebrate species-far more than live snails or non-living substrates. Additionally, commercially valuable species prey on hermit crabs, such as cod, ling, and wolf-fish. With these findings of effects on animal behavior, the microplastic pollution crisis is therefore threatening biodiversity more than is currently recognised so it is vital that we act now to tackle this issue before it becomes too late."

Drones, robots and autonomous systems can transform the natural world in and around cities for people and wildlife.

Part of pandemic preparedness is acknowledging that human, wildlife, and ecological health are inseparable.
