Biodiversity is a concept that's commonly referenced, yet regularly misunderstood. The complex_______ not only refers to the unbelievable variety of life on Earth, but to how everything from genes to entire ecosystems interact to make the planet habitable. The bad news: science shows that biodiversity is _______ worldwide at a faster rate than at any time in human history. That’s obviously devastating for everything in nature--including us.

“If biodiversity disappears, so do people,” says Dr. Stephen Woodley, field ecologist and bio-diversity expert with the International Union for Conservation of Nature. “We are part of the _______ and we do not exist without it.”

Preventing such a catastrophe, says Woodley, begins with understanding why biodiversity is declining, and then taking action to _______ course.

“The two greatest _______ of biodiversity loss are habitat loss, primarily on land, and overexploitation, primarily in the ocean,” Woodley says. He explains that we can solve these problems by permanently _______ more lands and oceans and managing them for their conservation values.

That's the mission of the global Campaign for Nature, a partnership of the Wyss Foundation and the National Geographic Society. Instead of simply protecting 30 percent of the Earth, the_______ also encourages nations, in full partnership with local communities, to focus on the right 30 percent. Those areas, says Woodley, _______ the most important biodiversity, such as endangered species and ecosystems and rare species and ecosystems.

The campaign also recognizes the importance of_______ local rights. Local peoples manage or hold tenure(保有权) over lands that support about 80 percent of the world's biodiversity, making it ________ for these communities to be full partners in developing and implementing strategies.

________, protecting the health of key biodiversity areas is vital for tackling climate change, says National Geographic Explorer-in-Residence Dr. Enric Sala. Pairing the international Paris Agreement to combat climate change, Sala's paper asserts, “would ________catastrophic(灾难性的) climate change, conserve species, and secure essential ecosystem services.”

“Biodiversity is stability,” says Sala. “Trees, wetlands, grasslands, peat bogs(泥炭沼泽), salt marshes(盐沼), healthy ocean ecosystems, mangroves(红树林), and plants ________ much of the carbon pollution humans put into the atmosphere. Yet, right now, less than half of the planet is in its natural state, which isn't enough.” Bottom line: Nature needs us to act-now. “Moving to Mars is not a(n) ________,” Sala adds. “The only conditions for our life and for the prosperity of human society are here on Earth ...we are ________ protecting it.”
