Pollution of the world's water seriously threatens the elaborate sensory system of marine animals. Small amounts of some chemicals may not be directly poisonous, but they may have indirect, often invisible effects. They may destroy, suppress, mimic, or mask vital phenomena, garbling the messages on which aquatic life depends, confusing sea creatures, and altering their behaviour.
Pheromones are the naturally secreted chemicals by which water animals communicate up one another. Animals use these chemical messages to guide their migrations; discriminate between individuals; recognize sex and reproductive states; and sense aggressors, predators, friends and their young.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
