For example, according to weak sustainability, replacing a natural forest with a park or agricultural land can be considered sustainable if the recreational or economic value equal the value of the biodiversity lost and further environmental impact caused. According to strong sustainability, cutting down trees in a natural forest and planting ...
For example, the manufacture and use of nitrogen fertilizer contributes around 5% of all global greenhouse gas emissions. [30] Livestock farming is a major source of greenhouse gas emissions. [31] At the same time, livestock farming is affected by climate change. Farm animals' digestive systems can be put into two categories: monogastric and ...
As the world population rises and economic growth occurs, the depletion of natural resources influenced by the unsustainable extraction of raw materials becomes an increasing concern. [5] The continuous alteration of the environment through water, mineral, and forest exploitation poses increased risks of climate-based displacement and conflict ...
Overexploitation does not necessarily lead to the destruction of the resource, nor is it necessarily unsustainable. However, depleting the numbers or amount of the resource can change its quality. For example, footstool palm is a wild palm tree found in Southeast Asia. Its leaves are used for thatching and food wrapping, and overharvesting has ...
Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater. Pollutants from farming include sediments, nutrients, pathogens, pesticides, metals, and salts. [1] Animal agriculture has an outsized impact on pollutants that enter the environment.
A farm that can "produce perpetually", yet has negative effects on environmental quality elsewhere is not sustainable agriculture. An example of a case in which a global view may be warranted is the application of fertilizer or manure, which can improve the productivity of a farm but can pollute nearby rivers and coastal waters (eutrophication ...
The major proximate drivers are biophysical factors and unsustainable land management practices, while the underlying drivers are social, economic, and institutional factors. [ 1 ] Land degradation is a global problem largely related to the agricultural sector, general deforestation and climate change .
Example of decoupling: Countries that managed to reduce their greenhouse gas emissions (working towards a low-carbon economy) while still growing their economy. In economic and environmental fields, decoupling refers to an economy that would be able to grow without corresponding increases in environmental pressure. [1]
