According to strong sustainability, cutting down trees in a natural forest and planting ...

The same can apply to the climate crisis, which may cause sea level rise on some Pacific islands. This type of damage is often not valued by the market, preventing those affected from being compensated.
Examples of environmental impacts of animal agriculture: Meat production is a main driver of deforestation in Venezuela; Pigs in intensive farming; Testing Australian sheep for exhaled methane production to reduce greenhouse gas emissions from agriculture; Farms often pump their animal waste directly into a large lagoon, which has environmental ...

[16] [17] The definition of sustainable agriculture varies depending on whether it is being defined within political or scientific discourse. [18]
Potential ecological issues could include the dispersal from agricultural habitats into natural environments, and host-switching or adapting to utilize a native species. In addition, predicting the interaction outcomes in complex ecosystems and potential ecological impacts prior to release can be difficult.
A problem with defining land degradation is that what one group of people might view as degradation, others might view as a benefit or opportunity. For example, planting crops at a location with heavy rainfall and steep slopes would create scientific and environmental concern regarding the risk of soil erosion by water , yet farmers could view ...
