PROBLEM: Background Paragraph: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators.

Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4]. 
Story: Two coastal communities  on two neighboring gulfs took different approaches to  bringing more money into the local economy. Davin village continued with commercial fishing and agriculture, while the village of Forx decided to mine sand from the nearby dunes, because it was very profitable. They did not think about the effect it would have on the environment. 
Question: Which village made less money by mining sand?

SOLUTION: Davin.

PROBLEM: Background Paragraph: Human populations are on the rise. The human population passed the 7 billion mark in October of 2011, and will pass 8 and 9 billion probably before the middle of the century. All these people will need resources such as places to live, food to eat, and water to drink, and they will use energy and create waste. Essentially, human population growth can effect all other causes of extinction. For example, more people on the Earth means more people contributing to global warming and pollution. More people also means more clearing of land for agriculture and development. Recall that development by humans often causes habitats to be destroyed. This destruction can force species to go extinct, or move somewhere else. 
Story: There are two identical neighboring planets, Krypton and Gotham, inhabited by the same species of creature. Both civilizations utilize the same technology and have the same city structures. However, the creatures on Krypton use substantially more energy than the people on Gotham. Furthermore, the inhabitants of Krypton have started clearing more land than Gotham. 
Question: Which planet has a larger population?

SOLUTION: Krypton.

Story: Sand mining in the north coastal region was stopped 20 years ago, but it still continues to this day in the south region. Both fishing communities there are still prosperous, but the southern one had a couple of bad years, with fish and other marine wildlife becoming more scarce. The southern beach had erosion problems as well. The northern beach recovered, and is suitable for tourism. 
Question: Which region made less money from sand mining?

SOLUTION:
northern.
