為什麼要保護野生動物？

02-25

從來沒有想明白過這個問題。果殼網那個《為什麼要保護野生動物》也寫得十分淺嘗輒止，只簡單說了幾句保護野生動物就是保護自然就是保護人類，可為什麼呢？保護自然環境我能理解，改變地貌氣候會產生變化，缺少樹木二氧化碳含量太高會溫室效應海平面升高人類沒有陸地繼續生存。那麼保護一個沒有人類干預也早晚會滅絕的野生猩猩的意義在哪裡呢？尤其是這個猩猩對人類沒有任何實用價值，從動物保護的角度來看不能被人參觀更不能和人親近，那人類還非要累死累活去保護它，它繼續活下去的意義在哪裡？為什麼物種的多樣性很重要呢。死掉90%其所在的生物璉和人類生存沒有任何瓜葛的動物，人類為什麼會因此受害呢？

1.保護生物多樣性，維持生態環境穩定

Promote Biodiversity

Biodiversity is essential for a healthy and functional ecosystem. If wildlife is extracted from its natural habitat, the delicate balance of the ecosystem will be disturbed which will then lead to disastrous results. For instance, there is a wide diversity of species living in a tropical rain forest. If any species should become extinct, the food chain will be disrupted affecting all the species. For this reason, promoting biodiversity is one of the main reasons why we should protect wildlife.

2.對人類製藥學和生物學發展有益

Beneficial For Humans

One can learn a lot from animals which can benefit the human race. For instance, a lot of medicines have been derived from the chemicals produced by animals. These medicines are then used to help cure various health conditions, such as heart diseases, disorders, and other illnesses. In fact, based on the statistics provided by the U.S Fish and Wildlife Service, more than 25% of the medicinal prescriptions given every year contain chemicals from animals. For instance, there are scientists who are studying venom from the pit viper to cure the symptoms of Melanoma, and the venom from a tarantula can help fight neurological disorders.

Wildlife protection is essential because if the animal is gone, it will be impossible to study and learn from them. Unfortunately, a lot of wildlife has disappeared from earth due to human activities, such as the Bali tiger, Mexican grizzly bear, and the Japanese wolf.

3.保護野生動物的生存環境對於人類的生存環境也有好處

Conservation Of Natural Habitat

When we conserve and protect the natural habitat of wildlife species, we enrich our planet. To do so, we must keep the animals in their natural place. Conservation of natural habitats will also be beneficial for humans since it helps keep the essential watersheds intact and ensuring clean, fresh water.

Today, there are now wildlife preservation programs wherein they allow the animals to roam freely in their natural habitat. Some of these programs also allow the animals to interact with humans. This is beneficial since it educates the people and raises awareness regarding the importance of protecting these wildlife species.

保護動物到底有什麼意義？ - wheeler 的回答

利用他們

首先，我們保護野生動物是保護野生動物免受人類活動的危害而不是其自然消亡，因為人類活動引起的野生動物數量變化並不包括在其自然消亡的原因內，影響某物種自然消亡而並非環境迫使其消亡的情況必將反作用於環境，導致環境變化。你可能說某些動物會受到天災，我們會保護那些動物，將其轉移。但這種情況的前提是人類在之前已對其造成了影響，導致其數量非自然變化進而危害環境。另外物種豐富度決定環境抗壓能力，舉個簡單的例子。一個環境只有人牛草1，那麼一場暴雪過後草1全跪了，人牛相繼全跪。另一個環境有人牛草1草2，同樣一場暴雪，草1跪了，但草2抗寒沒跪多少，整個環境還沒崩潰。
