How Oil Harms Animals and Plants in Marine Environments. The type of oil spilled matters because different types of oil behave differently in the environment, and animals and birds are affected differently by different types of oil.
However, it's not so easy to say which kind is worst. First, we should distinguish between "light" and "heavy" oils. Fuel oils, such as gasoline and diesel fuel, are very "light" oils. Light oils are very volatile (they evaporate relatively quickly), so they usually don't remain for long in the aquatic or marine environment (typically no longer than a few days). If they spread out on the water, as they do when they are accidentally spilled, they will evaporate relatively quickly.
However, while they are present, light oils present two significant hazards. In contrast, very "heavy" oils (like bunker oils, which are used to fuel ships) look black and may be sticky for a time until they weather sufficiently, but even then they can persist in the environment for months or even years if not removed. Oil Spills in the Ocean and Oil Pollution. Charles Moore - the Great Pacific plastic trash island. Pollution. Introduction of contaminants that cause adverse change Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light).
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source—that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed 9 million people worldwide.[2][3] L'exportation de déchets dangereux vers les pays en développement bientôt interdite - Déchets - Environnement. Les pays en développement ne serviront plus d'exutoire aux déchets dangereux des pays développés.
C'est ce qu'ont décidé les représentants des 118 membres de la Convention de Bâle réunis pour la 10ème Conférence des Parties à Carthagène (Colombie) du 17 au 21 octobre 2011. Un « ban amendement » doit en effet interdire aux pays de l'Organisation de coopération et de développement économiques (OCDE) d'exporter leurs déchets dangereux vers des pays non membres de l'organisation. Aujourd'hui, l'action de la Convention de Bâle est limitée à un contrôle des mouvements transfrontaliers des déchets dangereux, reposant sur le principe du consentement préalable du pays importateur. Adopté depuis 1995, cet amendement était resté lettre morte, notamment sous la pression de l'Australie, du Canada et des États-Unis (ces derniers n'ont toujours pas ratifié la Convention) . « La division entre pays de l'OCDE et non OCDE est dépassée »

They are also found on every continent, except Antarctica.
