Aquatic Invertebrates: Adaptations and Feeding Guilds INTRODUCTION Global warming and human's authoritative influence on the environment such as deforestation, pollution etc. are taking a bad toll on the diversity of the ecosystem. Global warming which has brought about increase in the temperatures is disturbing the natural cycle of the ecosystem. This has brought upon an increased droughts throughout the world. The droughts and increased heat has had negative impacts on local aquatic invertebrates.
TMA 01, QUESTION1. Some of the most serious environmental issues today are climate change, air issue, waste and land pollution, over population and water issue. 1. Climate Change, is undeniable a global environmental concern that is triggering a rise in the amount of major natural disasters like floods and hurricanes; which causes destruction in societies and the regions which they effect. Global warming will only cause an increase in these issues along with additional problems that could eventually end this civilization, if we don’t work hard on improving our efforts on managing all the different types of pollution and waste that contributes to this major concern.
Many worry about the negative consequences Global Warming may have on our Earth. It is believed that there will be detremental effects from sea to land. A rise in water levels causing the icecaps to melt. Melting icecaps would then release methane another greenhouse gas. The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain.
One of America’s most productive and environmentally sensitive ecosystems is facing collapse (America’s Wetland Foundation, 2009). Louisiana has sustained more wetland loss than all the other state in the continental United States combined due to a combination of natural and anthropogenic factors, including sea-level rise (Glick, 2013). Impacts of both humans and nature are devastating this diverse region and making a huge impact on biodiversity and also a way of life. The impact on these wetlands are far reaching. Wetlands perform many essential ecosystem services- carbon storage, flood control, maintenance of biodiversity, fish production and aquifer recharge, among others-services that have increasingly important global consequences (Keddy, 2009).
Reducing ground water levels will have consequences on the wider ecosystem and it will affect wetlands. Drilling in the Gulf of Mexico could damage the sea bed and even destroy ecosystems not even discovered yet. Also conflict over who will get the oil in the Arctic will be in dispute and will most likely be economically costly and large social conflicts with tribesmen there and
(E) (4) effect on photosynthesis (light independent reaction); increased rate with small increases, disruption with larger; increased rate of growth of (some) plants; possible increased rate of crop growth; effect of other limiting factors. (PS) (5) effect on transpiration; increased rate of water loss and hence wilting/dehydration; reduced stomatal opening may affect photosynthesis; possible consequences of drought on ecosystems. (T) (6) effect on respiration and metabolism; increased effect on growth and activity, especially of ectotherms. (M) (7) ecological effects of disruption of food webs and the dynamics of ecosytems, with changes in niches and hence communities. (EC) (8) effect on species; extinction of species that are unable to adapt, especially ones with specialised requirements; limited opportunity for plants and some animals to spread to more suitable conditions as climate changes.
Explain why oil exploration in the areas shown could lead to high economic and environmental costs. (10) The environmental effects of oil exploitation in these areas can vary depending upon the type, position and severity, however most pose the threat of being potentially severe. The explorations are taking place in deep water areas such as the Gulf of Mexico, the North Sea or the Arctic. Just one of the many potential risks and dangers of deep sea drilling is highlighted by the horizon oil rig spill of oil extracted from the sea floor. A spill in any of the deep sea areas would reduce the biodiversity of that area through reductions of bird populations, fish-stocks and populations of marine mammals.
Gore also asserts that global warming is caused by over population. Toxins and chemicals in the atmosphere impact each individual in the world. Because of the effects of global warming, the strength of hurricanes can change easily and cause an enormous amount of
If you meet a woman start talking about global warming, it’s a real ice breaker! Climate Change by Itamar Livne Climate change refers to any distinct change in measures of climate lasting for a long period of time. Over the last twenty years, human induced climate change and global warming have become areas of growing concern for scientists, environmentalists, and public policy makers. While research into the causes and impact of climate change continues, it is becoming increasingly clear that coral reefs are among those environments most threatened by this phenomenon. Even Australia’s own Great Barrier Reef has been taken under the impact of climate change and even got declared as the most damaged coral reef in the world.
This is significant, because if one species of animals departs, it causes the food cycle to be rearranged endangering the lives of multiple living organisms. They provide one of Canada’s largest negative impacts on the environment, releasing poisonous carbon dioxide emissions which are getting out of control. If these greenhouse gas emissions are not reduced it can result in the melting of polar ice caps in the Arctic. These oil sands are not only poising the air which we inhale, but also numerous waterways, food supplies, and if this process continues, possibly endangering the extinction of species. Green House Gas emissions are relatively caused by exponential increases in carbon molecules within the Earth’s atmosphere.
