A description of an environmental issue including the cause of the issue and its effects on the environment and people.

Question A description of an environmental issue including the cause of the issue and its effects on the environment and people. An explanation of how economics and personal lifestyle choice are involved in this issue. An explanation of how individuals, communities, and/or governments are working to address the environmental issue. Your opinion as to whether the issue is being adequately addressed and suggestions of ways it could be better addressed. Answer Natural resource depletion which occurs due to unsustainability of resource use is a serious crisis facing most parts of the world. Resource depletion is caused by use of natural resources at a rate higher that they can be replenished (Leigh & Olters, 2006). Resource depletion is closely tied to environmental sustainability. A number of factors are attributed to resource depletion. First, overpopulation has greatly contributed to resource depletion. High population growth puts more pressure on the available resources. Second, overconsumption and unnecessary use of natural resources have contributed to resource depletion....

SCI256-Why is it difficult to establish standards for acceptable levels of pollution? 

Question 1)Why is it difficult to establish standards for acceptable levels of pollution? 2)Explain, considering physical, climatological, biological, social, and/or ethical reasons. 3)What is one way natural ecosystems can perform wastewater treatment? Explain 4)Compare and contrast point and nonpoint sources of water pollution.  Which is easier to treat?  Why? Answer Question 1 Pollution comprises all the activities and actions that contaminate the environment. It is very difficult to difficult to establish these standards considering that pollution induces toxicity which is harmful. As a result, the toxic level will increase as the pollution agent continues to operate (Dunlap, 2014). Additionally, it is time-consuming to determine tolerable levels of toxic agent. Moreover, most organizations are not willing to spend most of their resources to neutralize their waste products unless legally compelled. Question 2 Usually, accepted levels of pollution are achieved when the benefits of reducing levels of pollution equal the cost incurred to reduce those effects. As a result, to achieve these optimal levels organizations should ensure that their waste productions are...

Environmental Pollution PowerPoint presentation

Environmental pollution refers to the contamination of the natural environment by naturally occurring or man-induced substances that leads to an interruption of the normal environmental processes. Pollution involves the introduction contaminants that are harmful to living organisms and including human beings. Environmental pollution can broadly be classified into three categories namely: soil pollution, air pollution, and water pollution. Pollutants are sometimes naturally occurring substances. These become contaminants when they occur in excess in the environment (Hill, 2010). Pollutants can be divided into two main categories depending on their decomposition properties. The two include biodegradable and non-biodegradable pollutants. Degradable pollutants are those that can undergo decomposition or be processed by organisms. Examples of these include organic waste products, inorganic salts, and phosphates. Biodegradable pollutants are considered harmless to a certain extent. However, their accumulation in large amounts can pose a serious threat to the environment especially if they exceed the environment’s capacity to assimilate them. Non-biodegradable pollutants are those which are not...

Global Warming

Question Some people you know say they don't believe that the climate is changing.  After this week's readings, how would you respond? Write a 525- to 700-word response including: How scientists learn about past global temperatures and climates. The greenhouse effect. Greenhouse gases and their role in current climate change. One piece of data scientists offer to show that the climate is changing globally (see this NASA website: http://climate.nasa.gov/evidence/ ). Expected impacts of climate change in North Carolina (this EPA website is very helpful: www3.epa.gov/climatechange/impacts/). Answer Global Warming Over the last few decades, the global climate has been changing in what is widely referred to as global warming. Global warming refers to the recent and ongoing rise in global temperatures near the earth’s surface (Houghton, 2009). This increase in temperature is attributed to the increase in concentrations of greenhouse gasses in the universe atmosphere and thus increasing the amount of solar heat that reaches the earth. From the time of last ice age, global warming has...

Integrated Pest Management (IPM) Paper

Question 1) In what ways is Integrated Pest Management (IPM) more sustainable than traditional methods of eliminating agricultural pests? 2) What role do you think fossil fuels should play in supplying energy to consumers in the United States?  What are some ethical issues associated with fossil fuels? 3) Which has greater future potential for energy production, wind or water power?  Which causes more environmental problems?  Explain. Answer SCI/256-Integrated Pest Management (IPM)   Question 1 Integrated pest management (IPM) is a process that used to solve pest problems while minimizing risks to the environment and populace. It is useful in the control of pests in agricultural, natural areas, and wild land. They are categorized into chemical, mechanical, cultural, and biological controls (Jacobson, M. Z. et al. 2013). Unlike the traditional methods, the IPM focuses on the long-term inhibition of pests or their harm by supervising the ecosystem. The traditional methods do not use the conservative methods such as pesticides and insecticides. Thus, there is a likelihood of occurrence of...

What are some ways people have affected biogeochemical cycles in your area?

Question 1)What are some ways people have affected biogeochemical cycles in your area?  Provide an example. 2)Read Chapter 7, then search the web for examples of environmental pollution incidents that involve a biogeochemical cycle. Summarize and share one example that you find. What harm did the incident cause? 3)Identify an invasive species in your area.  What are some environmental and economic impacts from this species? Answer Question 1 A biological cycle is a pathway by which a chemical substance moves through both biotic and abiotic compartments of the universe. In one way or another, human activities affect biogeochemical cycles. A good example of these activities includes burning of fossils thus transferring carbon iv oxide from lithosphere to the atmosphere (Davidson, 2007). Such activities accelerate the rate of biogeochemical cycles. Moreover, adding of fertilizers to the soil has also increased the levels of nitrogen and phosphorous in our soils. This activity leads to over-fertilization of aquatic life when excess amounts are carried to the nearby streams. Question 2 Coastal pollution...

Environmental science

Question 1)In environmental science, what is the difference between a positive feedback loop and a negative feedback loop? 2)Why is understanding the cycling of matter and energy in ecosystems important to environmental science? Provide an example. 3)Why can it be difficult to identify the boundaries of an ecosystem? How can environmental scientists resolve this boundary issue when studying an ecosystem? 4)Think about food chains and food webs. Describe a simple food chain that has at least five components. If you were the animal at the top of that food chain, how might having a food web instead of a simple food chain benefit you? Answer Environmental science Environmental science is the interdisciplinary academic field that seeks to integrate physical, biological and information sciences. Question 1 The positive feedback loop is that push of a system to a new state of equilibrium. It is a process that occurs in a feedback loop in which the effects of a small disturbance ion a system include an increase in the magnitude of...
