- About Invasive Species
-- Invasive non-native species are among the greatest threats to biodiversity worldwide. There are about 50,000 non-native species in the U.S. alone, costing about $125 billion each year in environmental damage and economic losses. While there are no easy answers, a new analysis shows that current approaches often just make the problem worse.

- Ballast Water & Exotic Species
-- Ballast is primarily composed of water and is full of stones, sediment, and thousands of living species. International shipping industries are responsible for the majority of these alien species invading foreign waters. Over 3,000 marine species travel around the world in ships' ballast water on a daily basis.

- Invasive Algae Smothering Florida Coral Reefs
-- An invasive, coral smothering seaweed has spread like a green tide across the reefs along the south Florida coast. Recent reports from divers and fishers show that the seaweed has become so thick on reefs in Florida's Palm Beach County, about an hour north of Miami, that it is forcing lobsters and fish away.

- Invasive Species
-- The introduction of non-native, or "invasive," species can cause irreversible harm to delicately balanced ecosystems. By far, the biggest source of invasive species is the ballast water that ships take on and discharge as they sail around the world. This water provides balance and weight to ships when they are not carrying cargo, and is important to safety and performance. It can contain all sorts of microscopic marine life, including eggs, cysts, larvae, and bacteria.

- Mediterranean fish colonise North Sea
-- Usually found in the balmy Mediterranean, the fish are migrating north as a result of global warming. Scottish fishermen are catching red mullet in large numbers, while cod and whiting are dying because the water is too warm.
