Are bioplastics better for the environment than conventional plastics?

Minnesota farmers are closely following the debate over how best to manage nitrates. Many farmers—no one knows the number exactly–are already taking action to lower their use of nitrates, which can contaminate water.

A new three-year project between the health department and the U.S. Geological Survey designed to improve the way arsenic, a carcinogen, is measured in private wells and to develop guidelines to help contractors avoid drilling high arsenic wells in the first place.

The amount of plastic debris in our oceans and water sources - especially nanoplastics that are increasingly prevalent in our food chain - is so enormous it's often beyond comprehension, and immensely difficult to address. As countries continue to industrialize and single-use products become more commonplace, the flow of harmful plastics into the environment seems insurmountable. But a number of clever inventions and dedicated individuals are working to help get plastics out of our water - and more importantly - encourage practices to reduce, reuse, and recycle.

Nationally, only about a third of municipal solid waste is recycled. An initiative to use simpler, standardized signs and labels is helping communities reap greater benefits from recycling.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

Lack of access to sanitary bathrooms in the village of Kivalina, Alaska led to the implementation of a novel, home-based water sanitation system, currently being tested for effectiveness. The hope is that it proves to be a solution for areas all over the state with lack of access to clean water systems.

Property rights, circumscribed jurisdictions, and conflicts with neighbors exacerbate Native American efforts to restore tribal land and resources. Some tribes have found success by tapping into a trend of support from the government and conservationists.

Prescription drugs are greatly polluting the national water supply, causing researchers to begin looking for a method to better filter water and dispose of unused medicine.

Throughout India, wastepickers – people who scour landfills for garbage they can sell to recyclers – live at the bottom of society. But the city of Pune did something radical: with the help of a collective, they did away with expensive garbage trucks, and now all household garbage is collected by wastepickers with pushcarts. Pune saves millions of dollars each year and recycles more – and the wastepickers have decent wages and social standing. The concept is now spreading globally.
