Environmental changes are fueling human, animal and plant diseases, according to a study
Several large-scale human-caused changes to the planet, including climate change, biodiversity loss and the spread of invasive species, are making infectious diseases more dangerous to people, animals and plants, according to a new study. .Scientists have already documented these effects in more targeted studies that have focused on specific diseases and ecosystems. For example, they found that a warmer climate could help the expansion of malaria in Africa, and that a decline in wildlife diversity could increase cases of Lyme disease in North America.But the new research, a meta-analysis of nearly 1,000 previous studies, suggests that these patterns are relatively consistent across the globe and across the tree of life.“It's a big step forward in science,” said Colin Carlson, a biolog...
