Sickle cell disease is present usually in those of African or Mediterranean descent (Saladin 2007). About 1.3% of African Americans have sickle cell (Saladin‚ 2007). Sickle cell was originated in Africa where malaria was killing a vast number of people (Saladin‚ 2007). The sickle cell hemoglobin is not able to be digested by the parasites that cause malaria‚ making those with sickle cell resistant to malaria (Saladin‚ 2007).

Coastal and Marine Degradation Coastal degradation Many beaches around the world are polluted by industrial and household waste. Rubbish of all kinds such as plastic bags‚ drink cans and bottles end up on the beaches. Many factories have been built along the coast so that they can dump their waste straight into the ocean.

Case Study 1: Great Barrier Reef - 1. Introduction Coral reefs are on the most complex ecosystems on earth. They are predominantly found in the Indian Ocean and on the Western edges of the Pacific and Atlantic Oceans. The global distribution of coral reefs is influenced by a number of factors‚ including life and sea surface temperature. Coral reefs require such a unique set of biophysical interactions that they are highly vulnerable to human-induced change. For example‚ just a small change in sea

The temperature of the Riparian zone affects the physical and the chemical properties of the water and largely influences the organisms affecting their feeding‚ metabolic rates and reproduction. It also affects how much oxygen can be dissolved in the water and how quickly the nutrients will be cycled through the water. Oxygen is better dissolved in cold water because gases are trapped by water molecules at colder temperatures. When temperatures rise‚ the molecules move around more‚ and gases‚ such

Fish depend on certain characteristics of their habitat‚ including temperature and turbidity. Fish depend on certain habitats for certain stages of their lives‚ for example‚ when a smallmouth bass is spawning it might want to lay it’s eggs in a sandy spot opposed to a rockier one. In addition‚ certain types of fish use both salt and fresh
