We talk with Carl Schreck, USGS biologist, on the effects humans are having on aquatic life by introducing chemicals and waste products into lakes and streams. How do these contaminants affect aquatic species' reproductive systems, metabolism, mood, growth development, and more? Listen to find out.

Each year hurricanes and tropical storms cause billions of dollars worth of damage to the Eastern United States. With the peak period being August and September, it's the perfect time to remind ourselves of the risks and discuss what research the USGS does in regard to hurricanes and strong storms.

We catch up with Tom Armstrong, Senior Advisor to the Director on Climate Change, to ask him some burning questions about how climate change is affecting the planet and our lives.
