I had to leave these fascinating chimpanzees for my students and field staff to continue studying because, finding they dwindled from about two million 100 years ago to about 150,000 now, I knew I had to leave the forest to do what I could to raise awareness around the world.
我就必须告别这些神奇的黑猩猩 我的学生和研究基地的工作人员留下，继续研究 因为，了解到这些黑猩猩的数量 从100年前的200万只减少到如今的15万只， 我知道，我必须离开丛林， 尽我所能，提高全世界对这一切的意识程度。
