Wildlife in Sin City

Singapore is such a safe and peaceful city to the point of being boring. The wildlife here were those behind bars, to be kept at a safe distance. They are wildlife after all. But the bored citizens would amuse themselves with some pet dogs, pet birds and pet fishes, like the thousand dollar carps in district 9, 10 and 11. The owners feel very safe, the pets are also safe.
 
Then things happened. A crocodile was spotted in Sungei Buloh and it caused a stir, so much attention. Then a family of otters was also found there, a few hornbills, and wild boars around the reservoirs. The people got so excited with the wild life. They have not seen them in their entire life and found them so novel and charming in their own ways. They are so nice, cannot possibly cause any harm here. Everyone was endeared to them. I took many photos of the croc, the hornbills and the otters in Sungei Buloh.  They even commissioned David Attenborough to do a special series on the wildlife in Sin City.
 
And because life is good in Singapore, the new migrants started to multiply. Otters were everywhere, even in the city and canals. Hornbills became accustomed to HDB flats. Have yet to see the crocodiles outside Sungei Buloh. Oh, I forgot, the monkies are still in Bukit Timah and MacRitchie Reservoir area. The only nuisance was the crows. With their increasing numbers some even attacked people. Fortunately their wild behavior led to their termination and not many were found in the city anymore. Some have become PRs in Sungei Buloh and attacking the smaller birds, the local residents.
 
The latest, hornbills attacked pet birds hanging outside HDB flats and devoured the pet birds, and eating fruits planted on the corridors. Otters sneaked into private ponds to eat the thousand dollar pet carps. Wild boars digging into gardens and destroying the manicured parks and paths. Some even attacked people in their path.
 
This is only natural. When they grow in numbers, not only that they have to compete for food, they grow in confidence, and knowing that the citizens are harmless and hapless, they would attack, applying the law of the jungle, the fittest shall survive. The locals had no chance against the wildlife that had made this city their permanent residence. They are bigger, fiercer, hungrier and still have the wild instinct of survival.
 
How long would it last before the locals got terminated and replaced by the foreign wildlife? I mean how long would the local wildlife be made extinct or forced to migrate elsewhere and their habitat, their homes, be taken away from them when the foreign wildlife make this their new home, when their number grows and become a majority here?
 
The pet birds in HDB flats are fearing for their life. How about the rich carps in district 9, 10 and 11? Do they feel safe within the confines of their walls and fence, that the wildlife would leave them alone?
