Lake Huron is one of the Great Lakes and a major part of our fresh water system, which contains many wildlife and species. The lake however, is in a real danger, adversely effecting habitats, fish, wildlife, and human lives. Lake Huron has become a dumping ground for many companies, dumping waste that contains many pollutants. Bacteria levels have increased in the lake which can cause serious illness. These pollutants have reduced water quality, contaminated soils, and damaged the Lake’s ecosystems.
They accomplish this by feeding on algae and bacteria. 8 Species of mussels are native to the river. The most prevalent are the eastern elliptio mussel and the eastern lamp-mussel. Mussels are eaten by a variety of birds, turtles, fish, muskrats and other mammals. Zebra Mussels are an invasive species that can cause harm to native species by attaching themselves to their shells preventing free movement and can even cut off their oxygen
This would be terrible for the people and creatures that rely on this mighty river to live. Dams, diversions and evaporation losses from reservoirs also contribute to the lessening of water available from the river, causing ecological consequences to wildlife living in and along the river. The Colorado River used to carry up to 85 to 100 million tons of silt or sediment to the Gulf of California where it deposited into the sea. The sediment helped things along the river path grow and flourish. Over the years, the silt has been collecting in Lake Mead, the nation’s largest reservoir, and it is predicted that over the next few hundred years this lake will fill up with silt.
The Arctic as most know is known for its fisherman and whalers, whom in the past overfished and whaling for the uses of oil, but cause a major downfall in the number of Arctic marine life. AS mentioned before with the climate change there will a larger number of fishing and whaling vessels due to the decrease of sea ice and the opening of Arctic waters that have never been accessible. Looking at the Arctic portal I found a list of restrictions that would be major to the fishing industry; 1. Restrictions on catch and effort, for instance by setting the total allowable catch (TAC) and allocating the TAC by means of national quotas. 2.
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.
During the last few decades, many thinkers from different disciplines have been searching for a new ethic to confront environmental ethics issues with – an ‘environmental ethic’. Whether religious or secular in nature, this must be able to define the environment and the proper relationship that should exist between human beings and the natural world. Today growing concerns about global warming (the effects of which global dimming, until now, has lead to a gross underestimation) underline the general acceptance that environmental preservation is an obligation both for present and future generations.
As centuries came and went health problems increased. The Earth’s natural resources were diminishing. Some believed the causes were natural; however, studies concluded that the steady increase in population is a co-conspirator. In the 1960s when noticeable natural disasters were occurring, the environmental movement became forefront. The oil spills in California and Massachusetts raised serious issues warranting an environmental conference to prompt international awareness of environmental concerns.
These are the clues that prove the climate is changing day by day. Begley suggests there is no certain way to stop climate change due to global warming, so now people need to find out how they are going to make efficient adaptation plans to keep the planet safe from climate changing threat. Rising global temperatures have been accompanied by changes in weather and climate. Small changes in the average temperature of the planet can be a large and potentially
David Zhang Ms. Khan ENG3U1-08 25 March 2012 Oryx and Crake: Climate Change Climate change is a tough subject for humans to deal with; ever since the Industrial Revolution, our dramatically increased consumption of energy over the century has brought about immense consequences. Abnormal weather conditions, an increased frequency of natural disasters, and rising sea levels are what many of us claim to be part of a “natural cycle”. However, it is no coincidence that we are on the wrong end of that “natural cycle”, and our behaviours and activities have only caused it to worsen. Climate change will worsen if we continue to disregard its existence and compromise with its consequences, rather than confronting the source of the issue and taking responsibility. Our irresponsibility could ultimately lead to the destruction of our world and civilization, as portrayed in “Oryx and Crake” by Margaret Atwood.
Human Intervention on Salmon Populations 1 The Effects of Human Intervention on Wild Pacific Salmon Populations Human Intervention on Salmon Populations Abstract Wild Pacific salmon have been studied extensively over the past thirty years, and much has been done to increase or at least maintain populations of varying species. Of these various sustainability tactics, many have proven to be responsible for declining populations. It becomes apparent that policy makers, lawmakers, and industry leaders have either not taken these results from scientific studies seriously or have other priorities. If human intervention on wild Pacific salmon populations does not change soon, this resource may be lost forever. 2 Human Intervention
