Wildlife and living organisms on Earth play a crucial role in maintaining the balance of the ecosystem as part of natural cycles. Imagine a time when wildlife no longer exists. Perhaps in the early days, life will continue as usual, but immediately afterward, the consequences of the disappearance of animals will become evident.
Consequences of the Disappearance of Animals
Wildlife experts believe that the absence of animals can lead to a chain of problems. Farshad Eskandari, a wildlife expert, says: "Many of humanity's achievements are rooted in nature, and a large portion of the potential of plants and animals remains unknown. Any species that goes extinct may take with it an unknown solution to one of humanity's future issues."

This expert emphasizes the necessity of preserving biodiversity and adds: "The value of wildlife is not just in what we use today. Each species can be part of a large genetic bank, and with its extinction, a part of this irreplaceable reserve is lost."
Historical Experiences and Natural Cycles
To understand the impact of the removal of a species, the story of sparrows in China is illustrative. In 1958, during the 'Four Pests' campaign, sparrows were targeted as harmful creatures. This action led to an increase in insect populations and agricultural pests, causing serious damage to agriculture. Alireza Hashemi, an ornithologist, states: "A new study shows that the decline in sparrow populations has led to a decrease in rice and wheat production."
Similar examples exist in Iran as well. Hashemi says: "Birds like the rose-colored starling in the northeast of the country help control insect populations, and their removal could have significant consequences."
This ornithologist also points to the role of woodpeckers in controlling tree pests and states: "The removal of these birds eliminates one of the natural tools for pest control." Scavenger birds also play a role in cleaning nature and reducing pathogens by feeding on carcasses. Therefore, their disappearance means losing part of the natural services that human health depends on.
How Can We Hope for a Better Future?
Eskandari concludes: "If one day wildlife completely disappears from the Earth, we will face chain reactions. From disrupting natural cycles and reducing genetic diversity to harming vegetation and increasing erosion." He emphasizes: "In such conditions, the Earth may take on an apocalyptic appearance, and human survival will also face serious threats."
Finally, Hashemi notes: "If one day humans disappear from the Earth, nature can gradually restore parts of the Earth to its natural state, but the Earth without birds and other wildlife species will be completely different. The absence of a bird or a squirrel may not be felt in a day, but its consequences will gradually become evident in human life."
