Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Around 40% of the Earth's original forest cover has been lost in the last 8000 years. [14] Desertification: Human-led changes in land management practices lead to changes in the ecological characteristics of a region. Land mismanagement and climate change can lead to a loss of ecosystem services, such as through degradation of soil. [15]

[ 10 ] [ 11 ] [ 12 ] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle , 1.2 billion sheep and 1 billion domestic pigs .
The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
In situ Biomining, is the one current method utilizing bioleaching that serves as an effective and viable replacement for traditional mining. [21] Because in-situ biomining, negates the need for the extraction of the ore bodies, this method stops the need for any hauling or smelting of the ore. [20]
Reuse of human excreta focuses on the nutrient and organic matter content of human excreta unlike reuse of wastewater which focuses on the water content. An alternative term is "use of human excreta" rather than "reuse" as strictly speaking it is the first use of human excreta, not the second time that it is used. [3]
