Jane Goodall

Sixty years after the start of her groundbreaking study of chimpanzces in the wild, the primatologist looks for a silver lining in the pandemic.

Chimpanzees have no     1     of deadly foes. Logging, mining, deforestation, human population growth,the bush-meat trade, the exotic pet trade,medical research, bad zoos: All have helped     2     the global chimp population from more than a million in 1900 to less than 300,000 today,   according to the international Union for Conservation of Nature. Now, add COVID-19, “The pandemic is a nightmare.” says Jane Goodall over the phone from her family home in Bournemouth. U. K. where she has been     3     in place since March. Because chimps share nearly 99% of human DNA, they are     4     to human-borne diseases. Human respiratory viruses are already the leading cause of death in some chimp communities. and while there have been no reports of COVID-19 outbreaks vet. all great apes are believed to be susceptible to the coronavirus that causes it.

To prevent transmission, scientists have     5     great-ape research across Africa, including at the center Dr. Goodall founded in Tanzania's Gombe Stream National Park. The     6     of a deadly virus wiping out vet more of this endangered species is “terrifying,” she says. This was supposed to be a festive time for Dr Goodall. 86. Galas around the world were meant to celebrate the anniversary of her     7     study of chimpanzees in the wild. which began 60 years ago on July 14. 1960. Instead， Dr. Goodall, who usually spends 300 days a year trotting the globe to give talks and meet leaders as an environmental activist, has been putting in long hours trying to     8     masks for local Tanzanians, raise funds for conservation projects run by the Jane Goodall Institute and cheer up staffers over Skype and Zoom.

But the new's isn't all bad. she hastily adds. Befitting someone who used the word “hope” in the titles of three of her past four books. Dr. Goodall isn't above squinting（斜视）to find a silver lining. “I think people are seeing that we brought this pandemic upon ourselves by     9     the warning of scientists.” she says. She hopes that policy makers recognize that raising animals in unhygienic factory farms or trafficking and selling them in     10     markets makes it easier for viruses to jump from animals to humans.

“I think this is waking people up,” she says.
