In EMA's first annual Benefit Gala, attendees discussed the long-term impact of a "dangerous" Trump administration and the need for increased awareness on environmental crises.

The Environmental Media Association (EMA) held its first annual Honors Benefit Gala on Saturday evening. Over the course of the night, Jane Fonda, Elizabeth Olsen, CEO of Oneida Nation Enterprises Ray Halbritter and President of LA Car Guy Mike Sullivan were all honored for their contributions, both locally and globally, to making the Earth a safer and cleaner place to live for generations to come. 

Elizabeth Olsen had all eyes on her during the Environmental Media Association's first annual benefit gala in LA Saturday.

The Ingrid Goes West ingenue, 29, made a sultry show in a chic black dress which dipped low to offer maximum amounts of cleavage.

Elizabeth, who is the younger sister of clothing designers Mary-Kate and Ashley Olsen, gave her stylish sisters a run for their money in her classic look.
