Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land".One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". [1]
An existing degraded natural ecosystem (e.g. a forest) might be restored to a healthy natural ecosystem, e.g. by removing pollutants or restoring key megafauna, such as deer. A degraded modified ecosystem (e.g. farmland) might be restored to a more functional modified ecosystems, perhaps by restoring hedgerows which can help improve soil quality.
[9] [10] [11] Habitat loss is a leading cause of species extinctions [11] and ecosystem service decline. [12] Two methods have been identified to slow the rate of species extinction and ecosystem service decline: conservation of quality habitat and restoration of degraded habitat. The number and size of ecological restoration projects have ...
Due to the major role trees have on ecosystems it is important to better understand components like the ecosystem, waterways, and species present in areas that are being re-planted. Prior research helps limit the depletion of biodiversity which can hinder medicinal discoveries, and alter gene flow in organisms.
SDG 15 is to: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss." [67] The proportion of remaining forest area, desertification and species extinction risk are example indicators of this goal. [31] [68
The danger of overexploitation is that if too many of a species offspring are taken, then the species may not recover. [12] For example, overfishing of top marine predatory fish like tuna and salmon over the past century has led to a decline in fish sizes as well as fish numbers.

Land restoration, which may include renaturalisation or rewilding, is the process of restoring land to a different or previous state with an intended purpose. That purpose can be a variety of things such as what follows: being safe for humans, plants, and animals; stabilizing ecological communities; cleaning up pollution; creating novel ecosystems; [1] or restoring the land to a historical ...
Forest restoration, when implemented appropriately, helps restore habitats and ecosystems, create jobs and income and is an effective nature-based solution to climate change. Moreover, according to FAO, forest and landscape restoration yields many benefits for the climate, including greenhouse gas emissions sequestration and reduction. [9]
