Chapter 8: Problem 21

List at least three negative impacts of fossil fuels that most concern you (or explain why not, if they don't concern you).

Short Answer

Expert verified
Question: List at least three negative impacts of fossil fuels that are of personal concern or explain why none are concerning. Answer: Three negative impacts of fossil fuels that are of personal concern include air pollution, climate change and global warming, and impacts on ecosystems and biodiversity. Air pollution can cause health issues such as respiratory and cardiovascular diseases, while climate change results in extreme weather events and temperature fluctuations. Lastly, ecosystems and biodiversity can suffer due to habitat destruction, water contamination, and pollution generated by the burning of fossil fuels. To address these concerns, it is crucial to explore alternative energy sources and promote a more sustainable future.

Step by step solution

01

Identify three negative impacts of fossil fuels

The first step is to identify at least three negative impacts of fossil fuels that concern you personally. Fossil fuels contribute to numerous environmental and public health issues, such as air pollution, climate change, and resource depletion. Here are three examples: 1. Air pollution 2. Climate change and global warming 3. Impacts on ecosystems and biodiversity
02

Describe the negative impact - Air pollution

Fossil fuels, when burned, release pollutants and particulate matter into the environment. These pollutants can cause various health issues, including respiratory and cardiovascular diseases. Additionally, air pollution from fossil fuels can lead to reduced visibility, acidic rain, and damage to infrastructure and vegetation. Air pollution is particularly concerning for people living in urban areas or those who suffer from pre-existing health conditions.
03

Describe the negative impact - Climate change and global warming

The burning of fossil fuels releases large amounts of carbon dioxide (CO2) and other greenhouse gases, which trap heat in the Earth's atmosphere. This results in a phenomenon known as global warming and leads to climate change, causing more frequent and intense storms, extreme temperatures, coastal flooding, and droughts. Addressing climate change is essential for the long-term survival of our planet, its ecosystems, and future generations.
04

Describe the negative impact - Impacts on ecosystems and biodiversity

The extraction, transport, and burning of fossil fuels can have negative impacts on ecosystems and biodiversity. Oil spills can damage marine and coastal environments, causing harm to plant and animal life. Mining for coal and other fossil fuels can lead to deforestation, habitat destruction, and contamination of water sources, which in turn affect the entire food chain. Furthermore, the air and water pollution generated by burning fossil fuels can also impact ecosystems, leading to reduced biodiversity and ecosystem degradation.
05

Final Thoughts

In conclusion, the three negative impacts of fossil fuels that concern you personally are air pollution, climate change, and impacts on ecosystems and biodiversity. It is essential to consider alternative energy sources, such as solar, wind, and geothermal power, to address these concerns and promote a more sustainable future.

One liter of gasoline \((1,000 \mathrm{~mL})\) has a mass of about \(750 \mathrm{~g}\) and contains about \(9.7 \mathrm{kWh}\) of energy. Meanwhile, a typical AA battery occupies \(7.4 \mathrm{~mL}\) of volume at a mass of \(23 \mathrm{~g}\), while holding about \(0.003 \mathrm{kWh}\) of energy. How much volume and how heavy would a collection of AA batteries be in order to match the energy in a liter of gasoline, and by what factors (in volume and mass) is gasoline superior?

Putting the cheapness of fossil fuels into perspective, a gallon of gasoline purchased for \(\$ 4\) might deliver \(6 \mathrm{kWh}\) of mechanical energy after accounting for efficiency of the associated engine. A laborer might be expected to export \(100 \mathrm{~W}\) of mechanical power, on average, and be limited to 8 hours per day. How many hours would it take for the laborer to accomplish the equivalent output of a gallon of gasoline? At a rate of \(\$ 15 / \mathrm{hr}\), how much will this cost you?

Explain, both in practical and mathematical terms, why the \(\mathrm{R} / \mathrm{P}\) ratio overestimates the time remaining for a resource if the rate of production (use) of that resource is continually increasing.

It is hard for many people to appreciate that fossil fuels will not just "run out one day," because they don't appreciate the substantial amount of work that must go into extracting the resource from a reluctant ground. What common, day-to-day personal experiences do you imagine contributes to this disconnect? \(^{89}\)

A gallon of gasoline contains about \(37 \mathrm{kWh}\) of energy and costs about \(\$ 4\), while a typical AA battery holds about \(0.003 \mathrm{kWh}\) and costs about \(\$ 0.50\) each, in bulk. By what factor are batteries more expensive, for the same amount of energy?
