Wetlands provide a multitude of ecological, economic, and social benefits. They provide habitat for many organisms and are nurseries for many saltwater and freshwater fishes and shellfish. Wetlands also hold and slowly release floodwater and snow melt, recharge groundwater, act as cleansing filters, recycle nutrients, and provide recreation. As of 2000, the contiguous United States was estimated to have about 105 million acres of wetlands remaining. Over the past 60 years, it has lost over 16 million acres of wetlands, and the loss continues at about 58,000 acres annually. Nearly one-third of the loss is due to urban development, with the rest being nearly equally divided between rural development, agriculture, and silviculture (predominantly logging). The southeastern United States is experiencing the greatest losses. The Emergency Wetlands Resources Act (EWRA) of 1986 requires the U.S. Fish and Wildlife Service to conduct status and trend studies of the nation's wetlands and to report the results to Congress each decade. The overall goal is to have no more net loss of wetlands. EWRA also established Bayou Sauvage National Wildlife Refuge along Lake Pontchartrain in New Orleans, Louisiana. According to the scenario, if the United States continues to lose wetlands at current rates, in approximately what year would the country run out of wetlands?

Population growth is at the root of many serious environmental problems. From the ancient Babylonians thousands of years ago, to Thomas Malthus two centuries ago, to present day neo-Malthusians, humans seem to possess an awareness of Earth's limitations in the face of growing populations.

GNI determines the Human Development Index (HDI) of a country, which is usually correlated negatively with gender inequality. That is, countries with a high HDI are expected to have better gender inequality indicators. 1. Reset the map. 2. Select Human Development Index (HDI). Then select Adult Females with only a Primary Education and select Split view window. 3. Select Gross National Income per Capita and Join with data layer: Adult Females with only a Primary Education.

Given its relatively moderate climate, population density is high across Europe. Areas of lower density correspond, for the most part, with areas of challenging physical geography. Instructions for Part A: 1. Add Population (Arithmetic) Density. 2.Zoom to Europe. 3. Select Show Political Labels. Based on the map, which area appears to have the lowest population density?

To bridge the global socio-economic disparities, international bodies such as the World Bank have tried several intervention measures. However, most of these initiatives have not been so effective. 1. Select Gross National Income per Capita and Join with data layer: Life Expectancy. Consider all the economic and social indicators. Should these trends continue over the next 25 years, what effect would this have on the socio-economic conditions of various countries in the world?

A person who migrates because of political push factors is not a refugee, and countries treat refugees differently than migrants. 1. Reset your map. 2. Select Net Migration. Select Refugees by Destination and Split map window. 3. Show Political Labels as necessary. A higher proportion of net migration and a lower percentage of refugees may suggest that people are immigrating into a country for mainly economic reasons.

Population growth is at the root of many serious environmental problems. From the ancient Babylonians thousands of years ago, to Thomas Malthus two centuries ago, to present day neo-Malthusians, humans seem to possess an awareness of Earth's limitations in the face of growing populations. Today, our ability to accurately quantify and monitor population growth is very sophisticated. We can measure growth and make predictions about world growth with mathematical and computer models. Despite long-lasting, rapid global population growth that is only recently starting to show signs of slowing, we have thus far been able to avoid global catastrophe. Can we continue to avoid disaster? Aside from contraception, human society and government policy can ________ to control population growth's negative effects on the environment.

Wetlands provide a multitude of ecological, economic, and social benefits. They provide habitat for many organisms and are nurseries for many saltwater and freshwater fishes and shellfish. Wetlands also hold and slowly release floodwater and snow melt, recharge groundwater, act as cleansing filters, recycle nutrients, and provide recreation. As of 2000, the contiguous United States was estimated to have about 105 million acres of wetlands remaining. Over the past 60 years, it has lost over 16 million acres of wetlands, and the loss continues at about 58,000 acres annually. Nearly one-third of the loss is due to urban development, with the rest being nearly equally divided between rural development, agriculture, and silviculture (predominantly logging). The southeastern United States is experiencing the greatest losses. The Emergency Wetlands Resources Act of 1986 requires the Fish and Wildlife Service to conduct status and trend studies of the nation's wetlands and to report the results to Congress each decade. The overall goal is to have no more net loss of wetlands. In the past 5 years, money for flood control projects in Louisiana has been cut dramatically. During that time, two simulations, one of a category 4 hurricane and one of a category 5 hurricane, indicated catastrophic damage and loss of life along the Gulf Coast. The levees were predicted to break, and massive flooding to occur, in part due to the loss of the sheltering wetlands. Wetlands in the United States ________.

have decreased due to human development

Human-caused climate change is affecting the boreal forests/taiga and tundra biomes due to rising temperatures, changes in precipitation, and other phenomena such as wildfires. For example, in 2016, a devastating wildfire destroyed about 6,000 square kilometers of forest around Fort McMurray and nearly overwhelmed the city itself.

When a species is moved from its native area to a new area, it can become an invasive species and damage its new ecosystem. What is one reason these species are able to do damage to an ecosystem?

When a species is transported, it leaves behind its predators and the diseases that previously kept its population in check. Therefore, the species is able to grow to large and damaging numbers.

Just as climate has affected the settlement and agricultural activities of humans, likewise, humans have extensively modified the physical environment. Such modifications have been facilitated by globalization and urbanization. Human action such as the operation of industrial plants and power generating facilities has increased acid precipitation.

Select Water Resources Vulnerability. Select Acid Rain (U.S) and Split map window. Compare the two maps and determine which statement is true.

Whereas the Southwest generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast.

Which of the following is/are an abiotic factor?

temperature

Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase atmospheric levels of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. Measurable warming of Earth due to these gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can melt permafrost in the tundra and increase precipitation in arctic areas. Global warming also can increase sea surface temperatures, melting sea ice in the Arctic and increasing the intensity of hurricanes in temperate and tropical coastal areas. Within communities, climatic change can shift interdependent species "out-of-sync," potentially causing indirect loss of species. Some models of climate change for North America predict that the grassland regions of the prairie states will become warmer and drier. This would result in ________.

the need to develop varieties of agricultural crops that tolerate desert conditions
