New data has revealed that the population of humpback whales has made a drastic comeback since commercial whaling was outlawed.
The population, which was once so small the species was threatened by extinction, has grown from just a few hundred to more than 25,000 since the 60s.
A University of Queensland study has found that population was able to flourish thanks to the outlawing of commercial whaling in 1962.

Though fears have now taken a new turn, for if the population was to continue growing at this rate it could become unsustainable.
It’s believed numbers are increasing by 10 percent every year, virtually doubling every seven years.
Scientists had originally expected the growth rate to slow down as numbers stabilised, but that doesn’t seem to be the case.
If the rate stays the same, by 2022 there could be at least 50,000 humpback whales.
