Regardless of your views on global warming‚ the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence‚ emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human

As shown by the title‚ our earth’s biodiversity is at crisis. But some may wonder‚ what is biodiversity? Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem‚ biome‚ or on the entire Earth. Interesting enough‚ my science teacher was starting on the Biodiversity chapter when I spotted this poster. We learnt about the classification of species using their common characteristics‚ but I realize that there are always exceptions. For instance‚ we know that mammals

Vulnerability and Resilience of Ecosystems * Vunerability is the sensitivity of an ecosystem to cope with stress. * Resilience is the ability of an ecosystem (or a component of an ecosystem) to adapt to a changing environment and to restore function and structure following an episode of natural or human-induced stress. * All ecosystems function in a state of dynamic equilibrium or a continual state of balanced change

Common aquatic ecosystems range from the largest oceans to the smallest creeks‚ but each aquatic ecosystem plays a pivotal role in global ecology. Each ecosystem consists of important aspects including nutrients cycling‚ biodiversity‚ and energy flow that contribute to the overall state of the ecosystem. However‚ the limited
