Sockeye salmon victual insects when they are younger, but when they get older they victual other fish and organisms in their environment (Groot and Margolis, 1991; Olson et al., 1998; Quinn and Kinnison,

Global warming is an important issue in the world today and concerning its future. There are many factors that affect global warming and its levels. Though some of these causes of global warming are due to natural events, many are the result of human structures and activities. Global warming is mostly due to the emission of greenhouse gases and can have very negative consequences on the environment and society (“Global Warming”).

Hence, improving riparian shading to lower water temperature by replanting trees at waterway banks is a well-known management practice (e.g., Merced River Ranch revegetation experiment) (Caissie, 2006). Alternatively, controlled river flooding is another management option, as it leads to a regular setback of community development and maintains the system in an immature, but highly productive stage (Junk and Wantzen, 2004). Growth is often an essential component of fish population dynamics models and, therefore, may be used by fisheries managers to mitigate the impact of climate change. However the basic understanding of the role of terrestrial organic carbon in aquatic food webs (Zigah et al., 2012), and the extent to which juvenile salmonid growth ultimately depend on terrestrial (allochthonous) and aquatic (autochthonous) primary carbon sources and how they vary along riverine longitudinal gradients is not fully known (Nakano and Murakami, 2001; Perry et al., 2003; Cole et al. 2006; Maier and Simenstad, 2009). Primary carbon sources within rivers vary spatially, seasonally, differ in quality, and are likely to respond differently to diverse environmental changes (Doucett et al., 2007). Allochthonous organic carbon subsidies link aquatic ecosystems to surrounding watersheds and can

There is a large amount research demonstrating the impact of global warming on our planet. As the overall temperature of the Earth increases, ice and snow masses are melting. As more ice and snow is lost, the ocean’s sea levels are rising. Additionally with less ice and snow, less sun light is reflected into space and instead it is absorbed by the planet. The continual absorption of the heat in sunlight gradually warms the planet along with other factors. Therefore, the loss of ice caps, glaciers, and snow is furthering the increase in the temperature of the planet.

Global warming is caused by several things. One of these is the release of carbon dioxide into the greenhouse gases in the atmosphere by using energy generated from burning fossil fuels.

Global-Warming is caused by the planet heating up, due to many greenhouse gases. A greenhouse gas is a type of gas that causes the planet to grow tepid, more than usual and at a quick pace. One specific greenhouse gas is carbon dioxide (CO2). Carbon dioxide is released, and bestowed,

Global warming is a phenomenon whereby the earth's average temperature increases. Global warming has a devastating effect on the Earth's climate. Scientists are still studying global warming effects, and have not reached a consensus about what will happen in the future. The melting of the polar ice caps and global warming are getting more and more attention lately. If melting glaciers caused by global warming, or it is a natural process - at this moment opinion of scientists and experts is diverge. There are many causes of the melting of the polar ice caps and global warming, some of which are natural. However, the activities of man are responsible for much of the rapid change that

The first definable cause of global warming is because human activities. In the past few decades the population of the world has increased rapidly. This has certainly triggered to increase pollution and ultimately effecting in the rise of earth's temperature. The major contributors of the climate change

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

Climate change is caused by the interaction of humans on the environment. Atmospheric concentrations of carbon dioxide — the main heat-trapping greenhouse gas produced by human activities. Carbon dioxide is a “greenhouse gas” (GHG) that traps heat in the atmosphere, warming Earth's surface. It is generated by natural sources such as wildfires and volcanic eruptions, and by human activities — primarily burning fossil fuels such as coal, oil and natural gas (Weeks 523). “We cause global warming by increasing the greenhouse effect, and our greenhouse gas emissions just keep accelerating,”

There is a range of possible causes for global climate change; however, there are two main ones that are the most realistic with backup support. These include the greenhouse effect and human activity. The greenhouse effect is the warming from trapped heat which is radiating from Earth to space

Heat trapped in the planet’s surface in turns raises up the sea levels because of these green house gasses that human activity or say primarily energy production produces. It causes one major issues that Earth’s inhabitants’ face, the melting of the polar ice caps. The polar bears are mainly affected by this dilemma, they lose ice sheets in where they live, hunt, and raise their cubs. Sheets of ice get weaker and weaker leaving no platform for these poor creatures to stand in causing them to drown to death. With the shrinking area of these ice caps, the chances of the polar bears striving and reproducing are getting slimmer and slimmer due to increasing ecological imbalance and damage from the results of producing energy.

A predominant factor as to why global warming happens is more gas particles exposed in the air because of an increase in gases produced by industries. Gases such as CO2 and SO2 are constantly harming our environment by regularly adding more harmful gasses into our atmosphere. Due to forest fires, industries, factories, and new found technology such as the car, many harmful gas molecules are surrounding us. These harmful gas molecules collide with our healthy atmospheric particles which make the amount of gas particles increase dreadfully. Since more collisions between these different particles are occurring, the average kinetic energy is raised therefore the temperature increases as well. As more particles are added into the atmosphere, it becomes denser and gasses are getting trapped into our

Global warming is caused by different factors, which are either natural or anthropogenic/human. Scientists have for long engaged in research on causes of global warming other than the natural factors. This has led to identification of many human related factors towards global warming. Greenhouse gases have been the major factors towards global warming. Both natural and human

Global warming is an expansion in earth 's temperature because of greenhouse gas emissions, fossil fuels, deforestations, modern and farming procedures brought about by the human, natural and different gas emissions. The climate is characterized as the examination of assembled climate information for long-term designs. The release of methane gas and carbon dioxide are the two fundamental drivers of environmental change. Environmental change happens in our world 's climate because of the aggregation of dangerous greenhouse gasses. Global warming has gotten to be the risk to everybody and everything on this planet.
