World Animal Day 2021 (October 4) is perhaps a good time to reflect that thousands of species of birds and animals have gone extinct so far. The rate of extinction is such that even now many species are literally disappearing every day. This is not only bad for the environment, but can even one day harm humanity due to the severely disturbed balance of nature. Serious efforts are needed to stop this worrying trend.
Fortunately, scientists are doing what they can to bring these animals back to the wild. Even when some species went extinct in the wild, scientists used translocation and captive breeding to get these species to roam the wild again.
However, this is easier said than done and a lot of care, research and data collection is required before a species is successfully reintroduced into the wild.
It’s not just about raising an animal in captivity and simply releasing it into the wild. Reintroduction into nature takes place in phases for a variety of reasons.
First of all, it must be considered that the reintroduction must not disturb the balance of the wild ecosystem from which the animal has become extinct. Once an animal has disappeared from its wild habitat, the ecosystem changes to accommodate the absence. New food chains can gradually develop and the reintroduction of the animal can again upset the delicate balance. Environmentalists must take into account the threat to the animal that is being reintroduced.
However, all conservation efforts over the decades are gradually bearing fruit. A study conducted in 2020 indicates that conservation actions between 1993 and 2020 saved up to 48 species of birds and mammals from extinction.
Examples of some of these animals are the Eurasian lynx, Tasmanian devil, Przewalski’s horse, red wolves, and Eurasian beaver.
