Drop into the Ocean

Produced in 2005, this 15 minutes short is a Greenpeace documentary which outlines the threats to our oceans and what can be done to restore their health.



It is currently used by Greenpeace to promote its new campaign for the oceans: Defending our Oceans

Greenpeace wrote:The key threats we address are:
Industrial fishing
Giant ships, using state-of-the-art equipment, can pinpoint schools offish quickly and accurately. These industrial fishing fleets have exceeded the ocean's ecological limits. As larger fish are wiped out, the next smaller fish species are targeted and so on. (Canadian Fisheries expert Dr Daniel Pauly warns that if this continues our children will be eating jellyfish.)

Simply put, more and more people are competing for less and less fish and worsening the existing oceans crisis. More

Bycatch
Modern fishing practices are incredibly wasteful. Every year, fishing nets kill up to 300,000 whales, dolphins and porpoises globally. Entanglement is the greatest threat to the survival of many species. Moreover, some fishing practices destroy habitat as well as inhabitants. Bottom trawling, for example, destroys entire ancient deep-sea coral forests and other delicate ecosystems. In some areas it is the equivalent of ploughing a field several times a year. More

Unfair fisheries
As traditional fishing grounds in the north have collapsed, fishingcapacity has increasingly turned to Africa and the Pacific. Piratesthat ignore regulations and effectively steal fish are denying some ofthe poorest regions of the world much needed food security and income,and those fleets fishing legally are only giving a small percentage ofthe profit to African or Pacific States. More

Global warming
The ocean and its inhabitants will be irreversibly affected by the impacts of global warming and climate change. Scientists say that global warming, by increasing sea water temperatures, will raise sea levels and change ocean currents. The effects are already beginning to be felt. Whole species of marine animals and fish are at risk due to the temperature rise - they simply cannot survive in the changed conditions. For example, increased water temperatures are thought to be responsible for large areas of corals turning white and dying (bleaching). More

Pollution
Another significant impact of human activity on the marine environment is pollution. The most visible and familiar is oil pollution caused by tanker accidents. Yet despite the scale and visibility of such impacts,the total quantities of pollutants entering the sea from oil spills are dwarfed by those of pollutants introduced from other sources. Theseinclude domestic sewage, industrial discharges, urban and industrial run-off, accidents, spillage, explosions, sea dumping operations, mining, agricultural nutrients and pesticides, waste heat sources, and radioactive discharges.
