A United Nations world wide ecological network can provide stability in the world, it will give room to natural habitats and can be a place of refuge for victims of war. When owned by the United Nations worldwide political stability will be provided by a visable role of the United Nations. If also considering routes of migration of wildlife this ecological network will be the main instrument next to a durable economy to keep our planet healthy.

Ecological networks contain four main elements:

Core areas:
These are areas where the primary function is biodiversity conservation. They are usually legally protected under national or European legislation (e.g. Natura 2000 sites). These areas should provide a substantial representation of key natural or semi-natural ecosystems and contain viable populations of important or threatened species. Land use within these areas is managed to give priority to biodiversity conservation.

Corridors:
These are areas of suitable habitat that provide functional linkages link between core areas. For example, they may stimulate or allow species migration between areas. Corridors can be continuous strips of land or 'stepping stones' that are patches of suitable habitat. Using corridors to improve ecological coherence is one of the most important tools in combating the fragmentation that is threatening so many of Europe's habitats. Generally speaking corridors can be associated with higher levels of land use, as long as their function is maintained.

Buffer zones:
Protected areas should not be considered as islands that are safe from negative external effects. The resource use that occurs outside them can have serious impacts on species and habitats within, for example air/water pollution from industrial activities around a protected area can have serious effects on species inside it. Buffer zones allow a smoother transition between core areas and surrounding land use. The size and utilisation of buffer zones depends heavily on the particular needs of the specific ecosystem and its local population.

Sustainable use areas:
These are remaining areas that can come under more intensive land use. But they should still take full account of the successful provision of ecosystem goods and services.

Stability of ecological networks
The relationship between ecosystem complexity and stability is a major topic of interest in ecology. Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem. Ecosystem complexity was once thought to reduce stability by enabling the effects of disturbances, such as species loss or species invasion, to spread and amplify through the network. However, other characteristics of network structure have been identified that reduce the spread of indirect effects and thus enhance ecosystem stability. Interaction strength may decrease with the number of links between species, damping the effects of any disturbance and cascading extinctions are less likely in compartmentalized networks, as effects of species losses are limited to the original compartment. Furthermore, as long as the most connected species are unlikely to go extinct, stability increases with connectance and nestedness.

Other applicationsAdditional applications of ecological networks include exploration of how the community context affects pairwise interactions. The community of species in an ecosystem is expected to affect both the ecological interaction and coevolution of pairs of species. Related, spatial applications are being developed for studying metapopulations, epidemiology, and the evolution of cooperation. In these cases, networks of habitat patches (metapopulations) or individuals (epidemiology, social behavior), make it possible to explore the effects of spatial heterogeneity.

A worldwide United Nations ecological network can be treated like the international waters.

The terms international waters or trans-boundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands.

Oceans, seas, and waters outside of national jurisdiction are also referred to as the high seas or, in Latin, mare liberum (meaning free seas).

Ships sailing the high seas are generally under the jurisdiction of the flag state; (if there is one) however, when a ship is involved in certain criminal acts, such as piracy, any nation can exercise jurisdiction under the doctrine of universal jurisdiction.

  • HI there. I like the idea. At the very least i spread it on my FB.

    It is a bit B.S. as you say snipes but at the very least it's a idea and going in a good way. We can't avoid those firsts very common sense afirmations.

    Keeping our planet healled is our only chance to get life (with us on) going on.

    IMAO
