Studies prove that carcasses of dead animals are important for plant growth. Researcher, Dr. Roel van Klink, conducted an experiment and concluded that carrion, the decaying flesh of dead animals, is essential for many species. Since, carrion of large animals is an extremely nutrient rich, ephemeral resource. The Oostvaardersplassen Nature Reserve found that the leaving the deceased animals on the ground has had a positive effect on biodiversity. The remains attract more insects and other arthropods and increase plant growth. After five months the plants were significantly larger than usual; the biomass was five times larger and nutritional plant quality was higher than the controlled sites.
Many debates have started from this proposition to keep dead animals in nature reserves. The European legislation requires any dead animal to be removed or destroyed, unless the aim is to provide food for endangered scavengers, like vultures. However, in places like Kenya and Tanzania, the Mara River’s ecosystem relies on rotting carcasses for sustenance. The disposal of wildebeests in the river, not only feeds scavengers, but also releases nutrients (phosphorus and carbon) into the river after their body decomposes and releases algae and bacteria, which also nourishes the fish. Although many nature reserves benefit from this concept, the Oostvaardersplassen nature reserve abused their power in 2017-2018. The reserve starved 3,300 deer, horses and cattle to death. These opposing views cause controversy on whether or not decaying animals are beneficial or detrimental to the economy.
Many ecosystems rely on rotting carcasses for sustenance. In the ocean, over 60 species live off of the “whale-fall” communities. This is when a large whale dies and their body sinks to the seafloor, into a new ecosystem. Scavengers (hagfish, sleeper sharks, amphipods, etc.) in the ocean tear away large pieces of soft tissue from the whale and later, “bone-eating” worms help to digest the whale carcass. These new species, developed from the “whale-fall” communities, can last decades in the deep ocean. Unfortunately, many whales suffer from commercial whaling, which also affects the food chain for animals that eat whales. This time of mass slaughter killed off as many as ninety percent of living whales during the 18th and 19th century. Therefore, some of the first extinctions in the ocean have been from whale-fall communities.
Personally, I believe that animal carcasses are beneficial to nature and should be allowed. Though, some people abuse their power to benefit their own land, by slaughtering animals. For that reason, there should be set regulations to ensure the safety of animals so people won’t just go around killing innocent animals for their own advantage.
