These harmful substances kill many species of fish and other marine life. The Chinook salmon is no exception. The chemicals are dumped into the rivers and streams and eventually these chemicals find their way to the ocean, polluting and effecting each area they pass through. The largest contributor to the decline in the Chinook salmon population is the commercial fishing industry. From a period of 1990-1992 815,000 Chinook salmon were caught by commercial fisheries.
If we do not take action all modern day marine life will die off and primitive organisms will once again, rule our oceans. Industrialization is a major contributor to the more evolved marine organisms dying off. From over fishing to over dosing our oceans in nutrients, it seems we’re trying to kill off all evolved marine life in our seas. Overfishing is a huge factor we must consider. Over fishing occurs when marine species are caught faster than they can reproduce.
In recent years, global warming is a topic that has received much attention. It’s is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants, which also known as the green house effect. Global warming can negatively affect the earth's delicate ecosystems. It has been linked to dangerous new weather patterns, the extinction of plant and animal species and so many others bad effects. Global warming is caused by pollution eating away at the ozone layer of the atmosphere, as well as greenhouse gases trapping heat.
We may not like it but climate change is one of the most important issues that have effects in many parts in our daily lives. If climate change isn’t slowed down it will have a significant impact on global temperature, sea levels, human diseases, and wildlife. Climate change will have an impact on global temperature. Greenhouse gases, emitted by power plants, automobiles, and fossil fuels, are keeping more heat in the Earth's atmosphere. This heat trapping is causing average temperatures to rise all over the world.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future. Of all the effects of global warming, the extreme weather that is taking place all over the world is the most obvious one.
Almost a quarter of the species present on land today might disappear by the year 2050. Underwater species also face a huge risk due to climate change. This is especially true for the species that are sensitive to warm temperatures. There are multiple components of climate change and are presumed to affect biodiversity on all levels – from organism to biome. At the most basic level, climate change will be able to reduce the genetic range of populations due to rapid migration and directional selection.
Under this circumstances, people start to focus on ample controls like control of pollution, Afforestation & regeneration of degraded areas, and etc. As we know, Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. With the rapid increase of earth temperature rise in sea levels and a change in the amount and pattern of precipitation. According to research I conduct, we can clearly find that the carbon dioxide emission is increasing rapidly. And most countries try to try their best to reduce emission of the CO2, but the process is still not work barely well.
"The Larsen B ice shelf… has shattered and separated from the continent as a result of warming." (USA TODAY, 1) As the global temperature steadily rises so do the results of this global heat wave, impacting the environment. Ice which has remained frozen for 100’s of thousands of years has begun to melt, and break off into the ocean. Once separated from the ice shelf it is only a matter of time before the ice is reverted back to water, causing a rise in global sea levels. The end result of this melt is costal flooding as the sea level rises beyond its natural barriers, and spills into areas below our current sea level.
One major reason to account for this shift is the utilization of fossil fuels into the environment. This process creates a multitude of carbon atoms that are released into the atmosphere, which is detrimental to our environment. To be exact, global warming is the process where there is an increase amount of greenhouse gases (such... ... middle of paper ... ...ze the importance of this issue and the urgent need for a resolution to climate change.

Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now.
