Question 8
Hydraulic fracturing, commonly known as fracking, is a method of extracting natural gas and oil from deep within the Earth. It involves injecting a high-pressure fluid, typically a mixture of water, sand, and chemicals, into underground rock formations to create fractures, allowing the release of hydrocarbons trapped in the rock. The sand helps to prop open the fractures, enabling the extraction of fossil fuels. Fracking has been a significant development in the energy industry, unlocking access to previously inaccessible reserves. However, it is a controversial practice due to concerns about its environmental impact, including potential groundwater contamination, induced seismic activity, and the release of methane, a potent greenhouse gas. The debate surrounding fracking revolves around balancing energy needs with environmental and public health considerations.

Question 12


Water-wise cities and those that are wasteful in their water use represent two distinct approaches to urban water management with significant implications for sustainability and environmental impact. Water-wise cities prioritize efficient and responsible water use, often implementing measures such as water conservation programs, smart irrigation systems, and the use of reclaimed water for non-potable purposes. These cities tend to invest in infrastructure that minimizes water waste and promotes long-term resilience in the face of changing climate patterns. On the other hand, cities that are wasteful in their water use may face challenges related to water scarcity, pollution, and increased strain on local ecosystems. Wasteful practices may include inefficient irrigation, excessive domestic water consumption, and inadequate wastewater treatment. The comparison underscores the importance of adopting water-wise practices to ensure the availability of this vital resource for future generations, promote ecological health, and mitigate the impact of water-related challenges.

Question 13
While the end of a drought in California may bring relief to water resources, paradoxically, it can exacerbate the risk and intensity of wildfires. During a drought, vegetation becomes drier and more susceptible to ignition, acting as fuel for fires. When drought conditions persist, there is often a reduction in vegetation growth, limiting the overall fuel load. However, the end of a drought can lead to increased vegetation, creating more combustible material. In California, where much of the landscape consists of chaparral and grasslands, a sudden influx of new growth following a drought can provide ample fuel for wildfires. Additionally, the return of rainfall may promote the growth of dense vegetation, creating interconnected fuel sources that can facilitate the rapid spread of fires. The combination of increased fuel availability and the potential for a more extensive and interconnected landscape of vegetation can contribute to more severe and challenging wildfire conditions despite the apparent relief from drought.

Why might the end of a drought in California paradoxically contribute to more severe and challenging wildfire conditions?
