The scientific data is clear: a diverse environment is beneficial to human health and the prevention of allergy illnesses. Nonetheless, population pressures and global warming are destroying biodiversity in the ecosystem and human living environment. In Europe, for example, the start of the plant growing season has advanced by an average of 10 days during the last few decades. These alterations have shifted food chains and created mismatches in ecosystems where diverse species have evolved synchronised dependencies on things like nesting and food availability, pollinators, and fertilisation. Climate change is also causing disease-carrying organisms' habitat ranges to shift, putting them in contact with prospective hosts who haven't evolved immunity. Climate change is particularly harmful to freshwater habitats and wetlands, mangroves, coral reefs, Arctic and alpine ecosystems, dry and subhumid areas, and cloud forests. Many species are ill-equipped to cope with the speed and scale of climate change, leading to extinction on a local and global scale. Furthermore, excessive carbon dioxide causes saltwater heat and acidification, which results in a progressive loss in phytoplankton and fish development, as well as an invasion of bacteria that depletes the oxygen content of water. These local alterations increase the size and scope of maritime dead zones and have farreaching implications for the food chain and biodiversity far beyond the Arctic.
