Major conservation efforts typically focus on entire ecosystems rather than just individual species. This approach is essential because ecosystems comprise a complex web of interactions among various organisms, including plants, animals, and microorganisms, as well as their physical environment. By focusing on the ecosystem as a whole, conservationists aim to maintain biodiversity, ensure the sustainability of natural resources, and enhance the resilience of ecological communities against threats such as climate change, habitat destruction, and pollution.

Ecosystem-based conservation strategies promote the health of all species within the ecosystem, allowing for more effective management of natural habitats. Protecting an ecosystem not only benefits the numerous species that inhabit it but also addresses larger environmental issues, such as water quality, soil health, and air purity. This holistic approach recognizes that the survival of individual species is often intricately tied to the overall health of their habitats.

In contrast, focusing solely on individual species may neglect the broader environmental context in which those species exist, potentially leading to ineffective or short-lived conservation outcomes. Efforts confined to only terrestrial or aquatic species are also limiting, as they ignore the interconnectedness that exists between different ecosystems and the species that inhabit both land and water environments.
