An ecosystem at risk is both vulnerable and resilient to natural stress and human induced modifications. Discuss this statement. • Relationships between natural and human-induced modifications and the vulnerability + resilience of ecosystems at risk • Issues related to the vulnerability and resilience of ecosystems at risk • Case study (GBR) with illustrative examples • Sustained‚ logical and cohesive response The Great Barrier Reef (GBR) is an ecosystem at risk that is both vulnerable

Acidification on Marine Ecosystems Ocean acidification is the ongoing warming and decreasing of pH in the earths water supply (Gray et al. 2016; PMEL 2017). The acidification is caused from the increase in carbon dioxide concentration within the earths atmosphere. The carbon dioxide then reacts with the water to produce carbonic acid and carbonate ions thus‚ decreasing the pH. Ocean acidification affects the ecology of everything on this planet. Mainly‚ the marine ecosystems and small organisms take

The effects of human activity on ecosystems and biodiversity Agricultural Practice Biodiversity is a measure of the diversity among organisms in different ecosystems. "Diversity" in this definition includes diversity within a species and among species‚ and among ecosystems.’ Monoculture is when a farmer produces or grows one single crop over a wide area. The advantages to the farmer of monoculture are‚ “the reduced plant competition for nutrients‚ space and solar radiation‚ control of unprofitable

He also faced the challenge of slavery‚ which was a problem that had plagued America since its early days‚ and a major cause in starting the civil war. Lincoln believed that slavery should be abolished‚ more importantly though he believed in the preservation of the union‚ and in the end he issued the emancipation proclamation in order to preserve the union. As a person‚ Lincoln held the ideal of slavery to be wrong‚ and morally believed that slaves should be freed. He believed in the equality of

between ecosystem and ecology? Ecosystem is the physical system (an open system) in which the mutual interaction between biotic and aboitic component motored by the energy component is studied. While the Ecology is the science which study the interrelation between Abiotic (inorganic) and Biotic (organic) components as well as the interaction among the biotic component. To make it more clear‚ ecosystem is the fundamental unit of ecological study. Ecology vs Ecosystem Ecology and ecosystem are

These components affect living organisms in many ways. Some of the soluble components and emulsions are poisonous‚ particularly to small organisms that do not have protective coverings or shells- Fish larvae‚ single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed

1) Make a promise to protect clean air. Nearly 37 million children live in areas with unhealthy polluted air‚ and many pollution- associated illnesses have been on the rise. Yet polluters and their allies in Congress have been fighting efforts to reduce toxic industrial pollution and are trying to weaken existing clean air protections. That’s why NRDC has joined other public health‚ advocacy and environmental organizations in the "Clean Air Promise‚" a national campaign to protect the health of
