How have ecosystem changes affected human well-being and poverty alleviation? All of these are affected by changes in ecosystem services. Collapse of the Newfoundland cod fishery 3. Intensive use of ecosystems often produces the greatest short-term advantage, but excessive and unsustainable use can lead to losses in the long term.
To be successful, sites for protected areas need to be carefully chosen, ensuring that all regional ecosystems are well represented, and the areas need to be well designed and effectively managed. Once an invasive species has become established, its control and particularly its eradication through the use of chemicals or through the introduction of other species is not necessarily effective and is extremely difficult and costly.
These sectors are directly dependent on biodiversity and affect it directly. The private sector can make significant contributions, for example by adopting certain agricultural practices.
Many companies now show greater corporate responsibility and are preparing their own biodiversity action plans. International agreements need to include enforcement measures and take into account impacts on biodiversity and possible synergies with other agreements.
Most direct actions to halt or reduce biodiversity loss need to be taken at local or national level. Suitable laws and policies developed by central governments can enable local levels of government to provide incentives for sustainable resource management.
Ecosystem restoration is generally far more expensive than protecting the original ecosystem, but is becoming increasingly important as more areas become degraded. Possible actions include eliminating harmful subsidies, promoting sustainable intensification of agriculture, adapting to climate changelimiting the increase in nutrient levels in soil and water, assessing the full economic value of ecosystem services, and increasing the transparency of decision making processes.Human interaction can also be very beneficial when preserving and saving an endangered species, since humans have a lot of knowledge about many organisms and their life styles, we can emulate their environments that may have been destroyed or changing so they can maintain a livable ecosystem.

An introduced species (alien species, exotic species, non-indigenous species, or non-native species) is a species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental.
Non-native species can have various effects on the local ecosystem.
