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 temperature and increasing water acidity. This program diverts to a discussion about the nature of scientific research. Download the audio or view the transcript of this ABC radio interview.

Australian curriculum content descriptions

(ACSSU112) Interactions between organisms can be described in terms of food chains and food webs; human activity can affect these interactions

(ACSSU222) Water is an important resource that cycles through the environment

(ACSHE119) Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world

(ACSHE223) Science knowledge can develop through collaboration and connecting ideas across the disciplines of science

(ACSHE121) Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management

(ACSHE134) Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world

(ACSHE226) Science knowledge can develop through collaboration and connecting ideas across the disciplines of science

(ACSHE136) Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management

(ACSSU176) Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
