Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still‚ the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources The ocean is one of Earth ’s most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It ’s used for transportation—both travel

no seasonality migration and aggregation of the poles would be mythical; also would be too cold for reproduction hence no “annual flush of productivity.” In the desert there would be now wet season which is an absolute requirement for terrestrial life in this biome. The earth’s sustainability would be minimal if the axial tilt were nil. Ratification of all earth’s species (besides extremists) would be embedded between approximately 20°N-60°N latitude; temperatures in these areas as follows 20°N

Background The world is in a constant change‚ and with it‚ every living being adapts to these changes. Ecology plays a major role in how the world and its inhabitants work. Before we start‚ to have a deeper understanding‚ let us define ecology. So what is ecology? In University of Western Cape’s introduction of their botany course‚ they defined ecology.

Reservoir defined The word reservoir refers to a place where large amounts of water get stored. The word reservoir comes from the French réservoir‚ which further derives from the Old French reserver‚ meaning "to reserve." Reservoirs are those water bodies formed or modified by human activity for specific purposes‚ in order to provide a reliable and controllable resource. a water body contained by embankments or a dam‚ and subsequently managed in response to specific community needs; or any natural

The physical environment includes light and heat or solar radiation‚ moisture‚ wind‚ oxygen‚ carbon dioxide‚ nutrients in soil‚ water‚ and atmosphere. The biological environment includes organisms of the same kind as well as other plants and animals. Because of the diverse approaches required

precipitation shifts directly affect biota‚ and scientists think that as the climate continues to change‚ the biodiversity in Northern Canada is particularly at risk. Because global warming can result in the decreasing of marine‚ freshwater and terrestrial communities‚ climate change has negative influences on biodiversity in Northern Canada. In order to conserve the biodiversity and improve the global warming‚ Canadian governments and schools have devoted to take actions on climate change. Climate
