Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
June Avant English 101 November 22, 2010 Global Warming Controversy Global warming is an increase in the average temperature of the earth’s atmosphere which causes climatic changes. Global warming leads to changes in rainfall patterns, sea level, negative impacts on plants, wildlife, and humans. Al Gore and Daniel Botkin both have great points about global warming. Botkin has a scientific perspective about global warming; however, Gore’s position is better. Al Gore uses facts and evidence to support his views about global warming.
Global warming is the result of greenhouse gases. The accumulation of greenhouse gases in the atmosphere leads to the alteration of weather patterns. Because temperature and moisture are essential to the way organisms and ecosystems develop, climate change impacts can be a major threat to mammals. Researchers estimate that global warming has the potential to severely alter 35% of the world’s existing habitats. Climate change may cause species loss as high has 20% in the arctic habitats
The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain. There may be oxygen poor zones in the ocean, coral extinction, and a decline in photoplankton (Skeptical Science, 2012). Our natural water springs may fail causing people in different areas of the globe to live without drinking water. There could be more wildfires, droughts that cause a loss of vegetation, and heat deaths or floods and storms (Enzler, 2007). The migration pattern of birds and other animals will change, there will be a disruption in our foodchain on land, and the possibility of loosing some species.
C) the production of CO2 by respiration. D) the burning of vast amounts of rain forests. E) none of the above 2) Which of the below statements about global warming is FALSE? A) Greenhouse gases allow sunlight to reach and heat the earth. B) Greenhouse gases prevent heat from leaving the earth.
It also releases large amounts of methane which is considered an earth warming gas. Just like methane , greenhouse gases are released. Greenhouse gases add to the greenhouse house affect which causes global warming. The gases help trap heat making temperatures. The raise of the temperature has been affecting humans and animals.
| | In biological magnification toxins concentrate at higher trophic levels because at these levels biomass tends to be lower. | | Sometimes harmful substances persist for long periods of time in an ecosystem and continue to cause harm. | | Since the Industrial Revolution, the concentration of CO2 in the atmosphere has increased greatly as a result of burning fossil fuels and wood removed by deforestation. | Carbon Dioxide Problems | One pressing problem caused by human activities is the rising level of atmospheric carbon dioxide. | | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period.
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
The main water supply of the Central Valley would cease to exist, thus leaving its inhabitants stranded and longing for a solution. Hence, if the Delta were to be eliminated through erosion or earthquakes, the amount of available water would diminish for most of California. For example, if we encountered a catastrophic earthquake, it could break down levee walls and within hours bring in salt water from the San Francisco bay. The salt level in the water ways would be detrimental to not only the drinking water but, to the wildlife and its ecosystem as well. Furthermore, it would also have a heavy influence on the amount and quality of farming.
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
