TEXTO:
For the first time in a century, the global population of tigers has increased. In 1900, there were
approximately 100,000 tigers throughout Asia, a number that plummeted to 3,200 by 2010. Scientists now
say the trend has changed. They estimate that the population has climbed to just under 3,900. The
increases have been seen in India, Russia, Nepal and Bhutan. Countries with tigers set a goal of doubling
[5] tiger populations by 2022, and research suggests there is enough habitat left to accommodate this growth,
if the animals are properly protected. The increase is due in part to improved protections against poaching
in some areas, although that remains an ever-present threat.
