By the second half of the 20th century, demands by some coastal states for increased security and customs zones, for exclusive offshore-fishing rights, for conservation of maritime resources, and for exploitation of resources, especially oil, found in continental shelves caused serious conflicts.
The growth of maritime transport and oil exploitation activities may increase the risk of oil spills.
That treaty did not establish a maritime boundary but provided for shared exploitation of petroleum resources in the part of the seabed claimed jointly by both countries.
Major threats to biodiversity in this region are industrial (trawling) and artisanal (line and longline) fishing, urban development, agriculture development, dredging and flow navigation, water pollution (runoff from the Orinoco and Amazon basins), mangrove deforestation, activities related to oil and gas exploitation, port activities, and maritime shipping [331].
The issues are those directly focused on economic activities: exploitation in deep water (P 7), securing vital maritime flows (P 18), bio-reducing the footprint of human activities (P 11), marine bio-economics (P 12) and, lagging far behind, sustainable tourism (P 14), the only issue with a score of "not important" reaching 20%%.
In this work, the possible exploitation of fiber-reinforced composites in the context of maritime transportation of compressed natural gas (CNG) is investigated.
Investigations of Mediterranean connectivity have increasingly turned toward maritime landscape models to frame questions of seaborne exploration, marine resource exploitation, trade and exchange, and seafaring culture.
This study also illustrates that the oldest and one of the most important maritime activities that has become a threat to diversity is human exploitation of marine resources.
In the 1970s the exploitation of offshore oil and natural gas became the major maritime industry, with Norway emerging in the 1990s as one of the world's leading petroleum exporters.
These pressures include different dynamics and levels of exploitation of fish populations, still high nutrient loads, and increased intensity of maritime transport as well as reduced input of toxic pollution and general progress in nature protection.
