This program deals with a range of human impacts on the Great Barrier Reef. Herbicides from land runoff have been traced to algae and sea grasses in river mouths and coastal zones along the Great Barrier Reef. Effects include retardation of photosynthesis and growth of corals. Other pressures on the reef include high water ...

This ABC In Depth feature article describes research on Australian white ibis - or 'tip turkeys' as many call them. They are regarded as a nuisance in cities, especially in the spring breeding season. But scientists fear they may become extinct as more pressure is put on the wetlands that are their native and adopted environments. ...

This 5 minute video segment from Catalyst highlights the vulnerability of some of our ecosystems and the way abiotic factors can have a dramatic effect. It also exemplifies the difficult process of having new scientific ideas accepted.

• TLF-IDM016232

This nearly 13 minute video segment from Catalyst explains how Fisheries scientists warn that if fishing around the world continues at its current pace, more and more species will vanish. The coral triangle is one particular area where biodiversity is at risk, and the top predator appears to be humans.
