The British conservationist once said, "What you do makes a difference, and you have to decide what kind of difference you want to make."
And Trump used that quote in her new book, "Women Who Work."
Goodall said she wasn't aware Trump was using her words, but she wasn't necessarily upset. Instead, she pushed Trump to take them to heart.
Goodall argued Trump administration policies have jeopardized wildlife, natural resources and national monuments.
She said, "[Ivanka Trump] is in a position to do much good or terrible harm. I hope that Ms. Trump will stand with us to value and cherish our natural world and protect this planet for future generations."
But how much Trump can, or will, do on the environmental front is up for debate.
But others note Trump hasn't explicitly supported climate policies. And because most of her work happens behind closed doors, her role and influence isn't explicit, either.
