In recent years, wild animals raised in captivity have been given more living space and more natural surroundings. Still, says Marcus Phipps of TRAFFIC, there are still some extremist animal rights groups overseas who wish to close all zoos and sea-world theme parks, with the goal of returning the animals to their natural habitats.
即使近幾年來被豢養的野生動物們，已獲得比較開闊的生活空間、更接近自然的環境，但根據來自加拿大的台北野生物貿易調查委員會駐台代表斐馬克的說法，在北美和歐洲仍有一些倡導動物權的激進團體，希望能促使動物園、海洋水族館停業，以幫助動物重返自然。
