Fossil fuels are the largest gas emitters in the world that helps to power electricity. Fossil fuels contribute to 75% of carbon and other gas emissions such as methane in the atmosphere. Although they are essential in daily life, fossil fuels have a huge impact on the environment contributing to global warming, acid deposition and pollution.
Burning fossil fuels at high temperature produces electricity but also leads to pollutants in the air and water. According to ZeeNews, Over the past 250 years burning fossil fuels have raised the atmospheric CO2 concentration by more than 40% over its preindustrial level of 280 parts per million. In May of 2013, the CO2 concentration in Earth’s atmosphere surpassed a milestone of 400 parts per million for the first time in human history. Many scientists consider this to be extremely dangerous for its impact on Earth’s climate (Emissions from fossil fuels to impact global warming). In addition, global warming is a very serious problem because many animal habitats are slowly disappearing and it is causing biodiversity loss. The polar bear is an example of an animal that is affected by global warming because the ice, which is an important habitat to the animal, is melting due to the increase in the climate. Biodiversity is very important on Earth because it helps create medication for people and without it, the Earth would not be able to function. Because fossil fuels are constantly being used for energy, it is affecting global warming
The ice caps are melting, and that causes the water level to rise. This makes it more difficult for polar bears to find food (Doc A). Climate change is also impacting animals due to forest fires, which kill millions of animals each year (Doc B). It also causes invasive species to enter places that were
Understand the background and importance
It can make us more deeply aware of the necessity and importance of ethical review to understand the historical background of ethical review. The editors of medical periodicals have the essential quality of ethical review, which refers to the basic ethical accomplishment that they must possess (Riis, 1980). Generally speaking these accomplishments include, understanding the basic ethical review of historical background, modern academic frontier information and scientific development level, can skillfully master the use of the relevant international and domestic laws and regulations and the principles of ethical review, skillfully effective review of human experimentation ethics problems, make its compliance with ethical principles, specification for judgment (Frenkel, 1979). Meanwhile, editors of medical journals should also pay attention to the hot spots, difficulties and controversies in the medical ethics that exist in the society, and enhance the expansion and deepening of their professional knowledge.
Annotated Bibliography: How Climate Change Is Affecting Our Planet
Controversy statement:
Climate change is been debated for over centuries now. People all around the world are taking action and reducing burning fossils to minimize the gasses in the atmosphere. Many people believe that climate change doesn't exists. But there are a lot of controversial topics that proves that climate change is real. In my opinion, climate change is slowly killing us and destroying our planet.
Climate change is an irreversible consequence of the damage we do to our Earth. If we do not change our ways, the global temperature will swell, causing an unchangeable series of events, consecrating detriments onto all the existence upon Earth. In only about 140 years, the average global temperature has increased 0.8 degrees celsius, and the ramification is the irreparable destruction of the place where we and millions of other species live. The most important consequence of climate change is the global increase in temperature and how that is affecting various animal species all over the Earth, the health of humans, and the rapid rise of sea level.
Sea level is now rising by 3.1mm per year. At this pace, more than 2.5 m sea level rise by 2040.
How does climate change affect Arctic animals? Climate change affects Arctic animals drastically by destroying their living habitat and food sources. Polar bears are having a hard time finding food because the ice caps are melting.
When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Many animals, whether they live in the ocean or the arctic are affected by climate change. Climate Change affects everybody in the world, even though some choose to ignore it, which is why it would be in humanity’s best interest to come together and find a solution.
Burning fossil fuels and the increase of greenhouse gases is causing the earth to warm. Although this gas is the source of the problem we still need it, without this gas the earth would be very cold. What the greenhouse effect is a layer of gas that surrounds the earth,
Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for
If the climate change would be the same in the future, the Mount Kilimanjaro 's glacier would likely be to disappear in the next decade. Disappearing of the environment from sea life animals would be the next affect. The polar bear and the walrus are 2 of the many sea life animals who live near ice sheets. Due to the ice melting, these ice sheets are decreasing quickly. Soon there will be no place for them to live anymore.
Global Warming
Proposal
Introduction
The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results.
The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
1. Introduction:
Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
The effects of Global Warming on humans society can be very bad. Because if, like I said in the last two paragraphs, there will be flooding and dry weather and fires and all kinds of stuff like that, and this will not only affect how much us humans have to pay for the damage, but it will also damage our homes, our lives, and our habitats and the places we live. Global Warming will have an effect on our food and water too. It can get to hot in some places for plants to grow, or to wet in others for plants to grow. All in all, the effects of Global Warming for anything is not going to be
Global warming can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding.
Global warming is the change in the average temperature of the earth is surface as a result of humans’ activity that pollutes the nature. The level of carbon dioxide has been increased in the upper part of the atmosphere which it leads to increase the average temperature on the surface which it causes many problems in many side of life including nature, health and economy. Increasing the concentration of carbon dioxide is due to release of poison gases to the atmosphere by cars, manufactures, oil field, burning of natural gases and smoking. Air pollution and climate change are a result of increasing the level of carbon dioxide around the world.
