Nature conservation

Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of the U.N.'s Convention on Biodiversity. Ultimately, these movements should be further promoted to encourage biodiversity and to conserve a functional ecosystem. Conservation goals include conserving habitat, preventing deforestation, maintaining soil organic matter, halting species extinction, reducing overfishing, and mitigating climate change. Different philosophical outlooks guide conservationists towards these different goals. The principal value underlying many expressions of the conservation ethic is that the natural world has intrinsic and intangible worth along with utilitarian value – a view carried forward by parts of the scientific conservation movement and some of the older Romantic schools of the ecology movement. Philosophers have attached intrinsic value to different aspects of nature, whether this is individual organisms (biocentrism) or ecological wholes such as species or ecosystems (ecoholism). More utilitarian schools of conservation have an anthropocentric outlook and seek a proper valuation of local and global impacts of human activity upon nature in their effect upon human wellbeing, now and to posterity.
