NYT: An Up-Close Look at a 2 Percent Difference

From the NYT article, An Up-Close Look at a 2 Percent Difference:

“Chimpanzees,” which will be shown on most PBS stations tomorrow night, tugs at the heartstrings, but tastefully. Sad, slightly sentimental music and luscious nature photography drive home the story of the thousands of chimpanzees who have been brought to the United States, mostly for human profit in medical research and the entertainment industry...Happily this is also the story of humans who are dedicated to making the chimpanzees’ remaining years far less traumatic.
