Warm winter leads to a significant decrease in road salt usage in Michigan
Michigan experiences a reduction in road salt application, benefiting budgets and the environment.
In short:
- Michigan's mild winter resulted in a 37% drop in road salt usage on state highways.
- This decrease may save the state approximately $10 million and mitigate environmental impacts.
- Experts suggest that warmer winters could reduce the future need for road salting.
Key quote:
"We’ve been trying to make a conscious effort to reduce our salt use."
— Tim Croze, statewide maintenance and operations manager for the Michigan Department of Transportation
Why this matters:
Runoff containing road salt can infiltrate freshwater systems, leading to elevated salinity levels in lakes, rivers and groundwater. This increase in salinity can disrupt aquatic ecosystems, harming or even killing plants and wildlife adapted to freshwater environments.

Argentina's wetlands under threat from new development projects
In Argentina's Paraná delta, known as "Earth's fourth lung," the push for luxury real estate threatens the region's diverse ecosystems and local communities, with private interests prioritizing spas and helipads over environmental and social health.
In short:
- The Paraná delta, a vital environmental and biological reservoir, faces severe threats from overdevelopment, including habitat destruction and pollution.
- Real estate developers are displacing local communities and altering the landscape with luxury homes and gated communities, impacting traditional livelihoods.
- Efforts to protect these wetlands are hampered by stalled legislation in Congress, reflecting a broader undervaluing of wetlands by society and political interests.
Key quote:
"We are the fourth lung of the world. Our delta gives oxygen to the planet, but today, they are damaging it terribly."
— Juan Carlos García, islander and descendant of the Indigenous Guaraní people
Why this matters:
The ongoing conflict in the Paraná delta serves as a microcosm of global environmental challenges, underscoring the need for sustainable development practices that consider health outcomes and preserve ecological integrity. We are reminded once again that in the battle for environmental conservation, "victories" are seldom permanent and forever subject to the politics of the moment.

Shell to divest Nigerian onshore oil operations amid environmental concerns
Shell's proposal, if approved without restrictions by the Nigerian government, could limit the oil giant's liability for decades of environmental pollution.
In short:
- Shell has agreed to sell its onshore oil business in Nigeria's Niger Delta to a consortium for $2.4 billion, aiming to reduce its West African footprint.
- The sale faces scrutiny from activists demanding Shell address longstanding environmental damages before finalizing the deal.
- The Nigerian government's approval is required for the sale, involving assets primarily owned by the national oil company NNPC.
Key quote:
“It would be a matter of very grave concern if the obvious legacy issues, especially the environmental and decommissioning issues, are not adequately and transparently addressed before and by any eventual divestment.”
— Ledum Mitee, local activist
