Environmental resource management is an issue of increasing concern, as reflected in its prevalence in several texts influencing global sociopolitical frameworks such as the Brundtland Commission's Our Common Future, [3] which highlighted the integrated nature of the environment and international development, and the Worldwatch Institute's annual State of the World reports.
However, climate change may preempt this FAO scenario as a study by the International Union of Forest Research Organizations in 2009 concluded that the stress of a 2.5 °C (36.5 °F) temperature rise above pre-industrial levels could result in the release of vast amounts of carbon [21] so the potential of forests to act as carbon "sinks" is "at ...
[32] [33] As of 1947, the planet had 15 to 16 million km 2 (5.8 to 6.2 million sq mi) of mature tropical forests, [34] but by 2015, it was estimated that about half of these had been destroyed. [35] [21] [36] Total land coverage by tropical rainforests decreased from 14% to 6%. Much of this loss happened between 1960 and 1990, when 20% of all ...
Radioactive Plutonium-244 has a half-life of 80.8 million years, which indicates the time duration required for half of a given sample to decay, though very little plutonium-244 is produced in the nuclear fuel cycle and lower half-life materials have lower activity thus giving off less dangerous radiation.
Potential resources: Resources that are known to exist, but have not been utilized yet. These may be used in the future. For example, petroleum in sedimentary rocks that, until extracted and put to use, remains a potential resource. Actual resources: Resources that have been surveyed, quantified and qualified, and are currently used in development.
The effectiveness of shifting of this act will only become clear over time as concerns regarding its implementation become apparent based on the fact that, historically, there has been a lack of capacity to enforce environmental laws and a lack of working tools to bring environmental-protection objectives into practice.
[1] [2] Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. [3] Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can ...
A more significant number or variety of species or biological diversity of an ecosystem may contribute to greater resilience of an ecosystem because there are more species present at a location to respond to change and thus "absorb" or reduce its effects. This reduces the effect before the ecosystem's structure changes to a different state.
