David Archambault II
When the Standing Rock Sioux Tribe took a stand against the oil industry and Federal government to block construction of the Dakota Access Pipeline just upstream of their lands, their protest quickly came to represent the long and arduous struggle of indigenous peoples everywhere to protect their sovereignty and ancestral heritage. In his Presentation, the leader of this ongoing efforts. Former Tribal Chairman Dave Archambault, will reflect on his Tribe's rich history, and how honoring the past has powered efforts to preserve that heritage for future generations. He will share his experiences with the "Standing with Standing Rock" movement, the leadership decisions he's had to make in the moment, and strategies he's learned for successfully carrying the fight forward. And finally, he will discuss next steps, not just for Standing Rock, but for all of Indian Country to stand together against injustice.
A mass extinction event 65 million years ago killed off the dinosaurs, along with three quarters of the species on earth. Today, the world is changing so rapidly that scientists fear another extinction event-- the sixth extinction -- is underway. What does this mean for people and for the millions of other species who share our planet?

Not only do children have more opportunities to be exposed to environmental chemicals, but as children grow and mature, their unique physiologic, developmental, and behavioral differences make them especially vulnerable to chemical exposures. Because children are smaller than adults, their surface area–to–body mass ratio is greater. Children eat more food and drink more water per unit of body weight than do adults, and breathe at a faster rate. Infants and children of all ages spend more time on the floor or ground than adults. Therefore, children will come into more contact with contaminants on these surfaces. Chemical exposures can disrupt the critical and rapid stages of development that occur in prenatal and early childhood life that can affect their health for a lifetime.
Dwindling Numbers for an Iconic Insect: A Conservation Biologist Ponders Moving Beyond the Documentation of Declines
Karen Oberhauser Dr.
Monarch butterfly populations have been declining over the last 20 years. Because insect numbers are notoriously difficult to assess, and because they often show large annual fluctuations, simply documenting this decline has been a challenge. It is now important to move beyond simple documentation, and toward responding to the challenge posed by monarch conservation, and insect conservation in general. I’ll describe the amazing biology of migratory monarch populations, how citizens and scientists are documenting monarch numbers across their migratory cycle, and then discuss what all of us can do to help preserve this charismatic insect for generations to come.
