The changing world has led to numerous developments in the ecosystem. Some of the species have become extinct, while new ones have emerged. The changes in the environmental patterns and ecological conditions leading to the innumerable kinds of living things. Notably, Australia has numerous invasive species that have emanated from human activity or by accident. Arguably, they have both the tremendous and detrimental effects on the life of the ecosystem. One of the primary challenges affecting Australia is the invasion of the non-native kinds of living organisms. The concern of this paper is to affirm that the non-native species in Australia pose a significant threat due to their continued concentration in various parts.
Effects of Non-native Species in Australia
The debate regarding the impact of the exotic species on Australia has attracted numerous arguments from scholars and citizens. Moreover, this type of living organisms consists of the plants and animals. Notably, human beings have termed the non-alien species as a risk to society due to the health issues, human harm, and economic loss (Jackson et al.). The primary examples of non-native animals in Australia include the dingo, echidna, koala, platypus, and kangaroo. Moreover, they get concentrated in the wildlife and zoos in various cities of Australia.
Notably, the non-native species impact the biodiversity of Australia. Moreover, the impact of the species on the ecosystem is unclear due to the direct and indirect trails of the effect on the ecosystem. For instance, since the introduction of the cane toad of non-native species in 1935, their population has immensely increased over time leading to the reduction of other species in the ecology (The Nature Conservancy). Therefore, the primary impact involves the reduction of other living organisms. The case is experienced in most parts of Southern Australia. Besides, large toads that poison any predator exhibit the tropical parts. The Southern parts of Australia contain the small and large types of toads, rendering it dangerous for other species that depend on their survival. Furthermore, the invasion of the toads in the Southern front leads to confusion; this is due to a decline of the predators’ population. For example, the stochastic weather conditions and Cane toads may cause their reduction. The presence of the toads as one of the non-alien species in Australia influences varied perceptions of the changes realized in the ecosystem, which may not be true.
Living organisms depend entirely on the ecosystem for their survival. The impact of the non-alien species on the ecology to pose a risk that threatens the wellness of human beings through the impact on fisheries, freedom, security, and health (Jackson et al.). The non-alien species become poisonous to other predators in Southern Australia and lead to a massive reduction of the different kinds of animals. Moreover, the presence of the numerous invasive types of organisms affects the fish.
The Non-native Species that have Invaded Australia
Non-indigenous species have led to numerous changes in the ecological conditions in Australia. Notably, the many invasive kinds of living organisms have invaded Australia. The freshwater fish in the Australian lakes indicates lack of diversity and little specialization (The Nature Conservancy). Therefore, the non-native fish have invaded the primary water points of Australia, leading to change in biodiversity. The Brumby is the non-alien species that got into Australia from Europe. The strong horses are concentrated in the northern territory and Queensland. Secondly, the cane toad and dromedary camel represent other species that have contributed to the environmental degradation in significant parts of Australia. The other non-native species include the European honey bee, which was introduced to Australia to aid in the pollination. The species get concentrated in the Northern and Southern parts of Australia.
Method for the Removal of Non-native Species
The non-native species both the adverse and tremendous effects on the ecosystem. Most notably, they have a negative impact on the ecology as they affect the wellness of human beings and cause environmental degradation. The primary non-alien species in Australia can be removed from the Southern, Northern parts, and Queensland through eradication. Moreover, the Australian government has a fragile ecosystem due to extensive mining activities that interfere with biodiversity (Diamond 378). Therefore, it should minimize the mining activities to conserve the environment and promote a balance in the ecosystem.
Benefits of the Removal
The non-alien species have numerous disadvantages to the ecology. Moreover, the Non-native living organisms affect the native species. The primary advantage of their removal from the ecosystem is that they would facilitate a balance of the ecosystem (Chesapeake Bay Program). Besides, it would enable the indigenous species to survive and achieve a balance in biodiversity. Additionally, it would improve the wellness of people’s lives through the nourishment of the fishing activities. Sustainability is crucial to the ecosystem, as it would trigger a balance in the ecology and other native species from becoming extinct. Poor sustainability practices insinuate the loss of lives, which, in turn, escalates into an imbalance in the ecosystem. The imbalance further leads to the starvation and death of other species in the long run.
Ultimately, the non-native species in Australia pose a significant challenge to the ecology. Arguably, they got introduced into Australia from different parts of the world. The Southern, Northern, and Queensland parts of Australia contain numerous non-indigenous species. The primary effects of the non-indigenous species include the reduction of the indigenous species, the imbalance of the ecosystem, health issues to human beings, and insecurity. Above all, the non-alien species can be removed from Australia through eradication.
