Floods and Pests
Southeastern Australia’s worst floods in 50 years have forced thousands from their homes and driven a frightening number of snakes and spiders into populated areas. Other wildlife are also scrambling for higher ground, including skinks, ants and crickets.
The hordes of spiders invading people’s homes have proven to be the most traumatic for many residents. But they are advised not reach for insecticides because the arachnids will eventually leave when the waters recede.
Researchers say they have found that the vast amounts of microplastics released into the environment from wastewater treatment plants each day may be “hubs” for antibiotic-resistant bacteria and other pathogens. A team from the New Jersey Institute of Technology says the plastic pollution forms a slimy layer of film on the surface of wastewater, which collects dangerous microorganisms and allows them to commingle and mix with antibiotic waste. The scientists say this poses a threat to marine life and human health if the plastic-borne pathogens bypass the treatment process, which is typically not designed to remove the plastics.
