Global access to clean water is at a tipping point. Increasing pollution degrades freshwater sources, exposing millions to unsafe water; 25% of Americans drink from systems not meeting current safety regulations.

Bryan Eagle, CEO of Glanris (a manufacturer of sustainable water filtration media), addresses this scarcity. He discusses actionable ways to reuse wastewater for potable and non-potable uses, and to find more economical methods for ocean desalination.

Eagle, who previously founded Skywire and helped launch the Discovery Channel, shared these insights at a TEDx event. Learn more at ted.com/tedx.

This "Eco Eye" episode, hosted by Duncan Steward, examines Ireland's water supply challenges. Parts of Roscommon endure continuous 'boil' notices due to contamination, and Dublin faced water shortages last October during a major web summit.

However, students at Kilmeena National School in Mayo, led by Principal Mickey Carney, are demonstrating exceptional understanding of water conservation. These children are now leading the way in protecting Ireland's most vital natural resource, providing important lessons for the community.

Hosted by Duncan Stewart, the 'Take, make, dispose' model describes our current linear economy: extracting raw materials, making products, then discarding them. This 20th-century consumerism has led to dwindling resources, overflowing waste, and significant environmental damage.

In contrast, the Circular Economy offers a progressive, efficient, and environmentally friendly alternative, mimicking nature by eliminating waste. The final Eco Eye series 12 program explores this model, showcasing Irish companies adopting it and featuring experts discussing its challenges and opportunities.

Ireland's public sector spends €9 billion annually on goods and services, totaling €100 billion over the next decade. This significant public expenditure presents a crucial opportunity to reduce carbon footprint, conserve energy, and boost environmental awareness among citizens.

Dublin fireman Neil McCabe demonstrates how this investment could foster environmentally friendly buildings and generate substantial cost savings. Transitioning to a green, low-carbon economy would not only save money but also create jobs.

The question remains whether local authorities and the government will embrace this vision. This discussion, hosted by Duncan Stewart, was published on Feb 18, 2014.
