In 1990, the Idaho Conservation League hosted a "Trash In" on the steps of the Idaho State Capitol to bring attention to the need for improved recycling and waste management in Idaho.

This year the Idaho Conservation League is celebrating 50 years of advocacy and hard work - protecting Idaho's public lands, waterways, air quality and wildlife.

Jonathan Oppenheimer, the ICL External Relations Director, joined Idaho Matters to talk more about the anniversary.
