Success stories about some endangered species!
Experts predict that more than 2 million species face extinction. Here are some species which (1) may survive and some others which could (2) come back!
Humans’ first ever success story (3) could be the Arabian Oryx. It disappeared completely in the wild in 1972 but now its population is growing. Scientists believe there might (4) be about 1,200 in the deserts in the Middle East.
And one of the most famous success stories (5) must be the bald eagle. When this eagle became the symbol of the USA in 1789, there were around 100,000 birds. However, people started hunting them and their numbers fell to 417 pairs by 1963. Due to strict laws that were introduced, the population has now grown. That (6) can’t be a bad thing, right?
And the largest of its species? That (7) must be Wallace’s Giant Bee – it’s four times bigger than the average bee. It almost disappeared but scientists have recently found it in Indonesia.
And in the future, some extinct animals like the Tasmanian Tiger, the Dodo or perhaps even some dinosaurs (8) may return. Scientists are beginning to experiment with their DNA to make copies and recreate them. I can hear you saying, ‘This (9) must be a joke! You 10 can’t be serious!’ but I’m completely serious!
