Analyse the human impacts affecting the nature and rate of change of two ecosystems at risk. All ecosystems are placed under levels of stress that must be withstood or overcome in the form of evolution in order to adapt and survive. These attributes determine the resilience and vulnerability of each and every ecosystem. These forms of stress fall under two categories; natural and human induced. In regards to natural stress‚ the term gradual is used as it happens at a slower rate and lesser magnitude

It stretches approximately 2300km from Papua New Guinea to Fraser Island. Overall the Great Barrier Reef system covers an area of over 348‚000km2 making a vast‚ very complex ecosystem. There is a long history of human activity and use on and of the Great Barrier Reef. Negative impacts on the Great Barrier Reef include climate change‚ oil spills‚ tourism‚ overfishing

The Deteriorating Great Barrier Reef Australian government officials in the last few years have been taking the protection of the Great Barrier Reef into their own hands. After creating an eye on the reef program‚ which specifically targeted the health of the Great Barrier Reef‚ scientists created algae killing bleach that would be applied to infected sections of the reef. Practices worked well until 2014 after a double dose of the bleach. After many tourist encounters with the reef a few individuals

The formation of this ecosystem is attributed to the dynamics of weather and climate‚ and the geomorphic‚ hydrologic and Biogeographical processes within the region. The atmospheric processes encountered within the Great Barrier Reef are ultimately responsible for shaping the reef ecosystem. The reef‚ which lies within Australia’s

Report: against coral bleaching On the Great Barrier Reef alone there are over 400 species of coral. These combine together to form the foundations of the greater structures of the reef. Microscopic organisms called zooxanthellae live inside coral structures and they nourish the coral host through the process of photosynthesis and through this‚ give colour and life to the reef. They are the source to the health and vitality of the reef and they live in a delicate balance with their habitat

Ever since the 1960’s‚ The Crown of Thorns Starfish have been destroying our magnificent Great Barrier Reef. Biotic factors are a major consideration of the outbreak of the Crown of Thorns‚ lack of predators and their high fertilization rate plays a massive role in this overwhelming amount of starfish. The main predator the COT meets is the giant triton snail1. But because of recent population problems making the predators lacking in numbers they have no way of reducing the crown of thorns population
