Sophia Environmental Science Milestone 3 You passed this Milestone 1 Which of the following is currently increasing because of human population growth and its associated impacts? • Non-renewa... ble resources • Land available for crops • Freshwater supplies • Sea levels CONCEPT Population Growth Solutions 2 Choose the true statement about global food production. • Examples of subsistence crops include tea and coffee. • Food production is dependent on suitable land, temperature and precipitation and soil health. • Many different crops are grown around the world, but rice is the most dominant. • Cash crops include only non-food crops such as tobacco and rubber.

CONCEPT World Nutrition 6 Choose the true statement about water on Earth. • Oceans cover about 50% of the Earth’s surface. • Freshwater is found in glaciers, ice, rivers, lakes and below ground. • Humans can easily access a large percentage of the Earth’s freshwater. • Oceans contain approximately 90% of the water on Earth. CONCEPT Water 7 Phyllis has an organic apple orchard. The round-headed apple tree borer can kill a tree, and most farmers spray a pesticide to kill the borers. But Phyllis uses neem oil, an oil from the seeds of an Indian evergreen tree, to interrupt the insects' life cycle. Of the other practices she has introduced below, choose the one that is NOT an environmentally friendly form of pest control. • She uses fungi-rich mulch and herbal sprays to boost the trees’ immune systems. • She keeps chickens in the apple orchard to control insects. • She plants herbs to attract native bees to pollinate the apple blossoms. • She treats larvae deep in the wood of a tree with a chemical repellent. CONCEPT Fertilizers and Pesticides 8 Which of the following is true about water supply and demand? • The amount of available clean water is increasing. • Water supply is fixed and unchanging. • Water use is growing twice as quickly as the population. • People waste less water than they once did. CONCEPT Water Availability 9 Choose the FALSE statement about undernourishment and malnourishment in the world. • Producing more meat is the most effective way to increase food access. • There is enough food produced on the planet to meet the population’s nutritional needs. • Some areas have more food than they can use while other areas don't have enough food. • Deforestation can create more arable land to feed more people. CONCEPT World Nutrition 10 Choose the statement that is NOT true about water availability on Earth. • Industry uses nearly as much water as agriculture does. • Many major aquifers have a notable reduction in available water. • 20% of the world’s population lives in an area where water is scarce. • More than a billion people do not have ready access to clean water. CONCEPT Water Availability 11 Of the options below, which is an example of a non-point source of water pollution? • A limousine company maintains a fleet of 15 cars in a garage. • A homeowner fails to repair a deteriorating septic tank. • Fertilizer and pesticides run off from the community’s two golf courses. • A factory discharges its wastewater directly into the nearby river. CONCEPT Water Pollution 12 Which statement describes the environmental impact of developed countries? • These countries use the least amount of the world’s freshwater supply. • These countries leave the smallest ecological footprint. • They have a higher rate of population growth. • They have a lower rate of population growth. CONCEPT Human Population Growth Agriculture Practices World Nutrition Water 13 Which of the following does NOT negatively affect groundwater? • Increased water consumption by humans depletes aquifers. • Development has caused rainwater to drain into sewers instead of into aquifers. • Runoff from household and agricultural chemicals filters into groundwater. • Humans are utilizing groundwater to generate electricity. CONCEPT Water Supply 14 Anna eats the last pickle for lunch. She decides to use the empty pickle jar to hold her paint brushes. Which waste disposal method is Anna practicing? • Combustion • Recycle • Reuse • Compost CONCEPT Solid Waste 15 Which of the following is an example of a regenerative agricultural practice? • Sadie uses natural processes to stimulate the formation of new topsoil. • Sally rotates crops regularly to help prevent pest outbreaks. • Timothy uses natural pesticides to keep his crops healthy. • Quinton practices no-till farming to maintain the fertility of the soil. CONCEPT Agriculture Impacts 16 People in developed countries consume approximately __________ of all meat. • 90% • 80% • 96% • 76% CONCEPT Agriculture Practices 17 Which of the following is NOT an impact of urban sprawl? • Watershed pollution • Reduced biodiversity • Increased crime in abandoned areas • Increased land for agriculture CONCEPT Urban Sprawl in the US 18 Which of the following is true about the ecological footprints of the U.S. and developing countries? • The U.S. standard of living requires 10 hectares of land per person, but a developing nation’s standard of living requires one hectare of land per person. • The U.S. standard of living requires five hectares of land per person, but a developing nation’s standard of living requires 0.5 hectares of land per person. • The U.S. standard of living requires 15 hectares of land per person, but a developing nation’s standard of living requires 10 hectares of land per person. • The U.S. standard of living requires two hectares of land per person, but a developing nation’s standard of living requires 0.2 hectares of land per person. CONCEPT Human Population Growth 19 A septic tank was not installed properly and waste water has risen above ground and flows toward a nearby lake. Which of the following is NOT likely to be a result of this occurrence? • Algal growth in the water will increase, eventually decreasing the oxygen supply of the lake's fish. • Drinking the lake water can cause disease. • The polluted water can break a link in the aquatic food chain. • The waste water will be diluted before it reaches the lake. CONCEPT Water Pollution 20 Select the FALSE statement about the benefits and impacts of dams from those listed below. • A dam can create new ecosystems, which increase biodiversity. • A dam can provide a dependable water supply for urban or industrial use. • A dam can provide a means of irrigation to a region with poor or unpredictable rainfall. • A dam can provide hydroelectric power, which is environmentally safer than burning fossil fuels. CONCEPT Water Supply 21 Which of the examples below describes an effort to address urban sprawl through urban green space? • The city converts an old factory downtown into affordable housing for young people. • The city razes a former dry cleaners downtown, cleans up the chemicals in the soil and builds a sculpture garden. • A new restaurant is constructed on a lot on the edge of town, bypassing several vacant lots within the city. • A small city maintains a park and forest within its downtown as new businesses build around it. CONCEPT Addressing Urban Sprawl 22 Which statement about agriculture impacts is false? • Monoculture can threaten human health because of increased chemical use. • Agroecosystems try to control a certain number of species in a limited area. • Fewer pesticides are used when monoculture is practiced. • Agroecosystems do not allow a natural progression of multiple species and ecological succession. CONCEPT Agriculture Impacts 23 Lillian always locks the cupboard in which she keeps the chemicals for the swimming pool. She has a curious four-year-old and she knows he wouldn't recognize the pretty colored vials as poison. One day, the pool maintenance person returned to his truck for a moment, and Lillian saw her dog sniffing at the open cupboard. Quickly, Lillian called the dog to her side and she scolded the maintenance person for leaving the open cupboard unattended. Lillian is most concerned about the which of the following factors of the chemicals inside? • Reactivity • Ignitability • Toxicity • Corrosivity CONCEPT Hazardous Waste 24 Toxic chemicals are filtering through the soil into groundwater, contaminating the drinking water in a nearby town. Which type of waste disposal most likely caused this phenomenon? • Dumping in the harbor downstream. • Dumping at a nearby landfill. • Composting at the community garden. • Combustion at the town's incinerator.
