Besides being interdisciplinary, environmental science is also a very new branch of study. In fact, this field of study largely

arose as a result of increasing evidence of human damage to the environment. Life has existed on earth for over 3 billion years, and its continued persistence depends on three main factors: the availability of solar energy, the presence of biodiversity, and the cycling of nutrients
Humans, however, who have only been around for about 200,000 years, have altered these principles of sustainability. For example, which of the following activities describe direct and immediate effects on nutrient cycling in the environment?
A. Clear-cutting of forests destroys habitats for wildlife and thus contributes to species extinctions..
B. Overharvesting of fish can have cascading effects on marine food webs.
C. Constant burning of fossil fuels at power plants increases carbon dioxide concentrations in the atmosphere, resulting in faster input of carbon into the atmosphere than the ocean and land can take up.

Answer:

C. Constant burning of fossil fuels at power plants increases carbon dioxide concentrations in the atmosphere, resulting in faster input of carbon into the atmosphere than the ocean and land can take up.

Explanation:

Nutrient cycling is the process that allows for a continuous and balanced exchange of nutrients between the earth, living beings and the atmosphere. This exchange allows life on earth to be allowed and managed. An imbalance in this exchange can cause very harmful effects that damage the entire system that the earth maintains.

An example of this is the imbalance caused by the excess burning of fossil fuels. That's because the constant burning of fossil fuels in power plants increases concentrations of carbon dioxide in the atmosphere, resulting in a faster entry of carbon into the atmosphere than the ocean and land can absorb.

Which of the following type of ceramics is used for making bricks?
VMariaS [17]

The correct answer is - c) earthenware.

The earthenware is the ceramics type that is used for the creation of bricks. Traditionally, the term brick has been used for the units composed out of clay. Nowadays, with all the new techniques and materials involved into the construction, a brick can be any rectangular unit that is laid in mortar. Still, a typical brick is composed out of the earthenware, so they can be from clay-bearing soil, lime, and sand, but also are used the concrete materials to give it more strength.

What are the geographic perspectives on climate change in Canada; list for the following:
Andreas93 [3]
Climate change will affect most aspects of our lives in Canada. Our economic, social and general well-being are all linked, both directly and indirectly, to climate. For example, climate influences the crops we grow, the productivity of our forests, the spread of disease, the availability of water, the health of ecosystems and the stability of our infrastructure. Changing climate brings many new challenges and, with them, the need to re-examine long-standing practices and assumptions.

Our climate is characterized by high variability, on both seasonal and annual scales. Although our economy, health and infrastructure are generally well adapted to current climate conditions, our vulnerability to climate is clearly evidenced by the impacts resulting from extreme weather and climate events. Losses from recent individual weather-related disasters in Canada are often in the hundreds of millions of dollars. Consider, for example, costs associated with the 2003 summer wildfires in British Columbia and Alberta ($400 million; Public Safety Canada, 2005), the 1991 and 1996 hailstorms in Calgary ($884 million and $305 million, respectively; Public Safety Canada, 2005), the 1997 Red River Flood ($817 million; Public Safety Canada, 2005) and 2003 Hurricane Juan in Halifax ($200 million). Multibillion dollar disasters also occur, including the 1998 ice storm in eastern Canada ($5.4 billion) and the Saguenay flood in 1996 ($1.7 billion; Public Safety Canada, 2005). The 2001 -2002 droughts, which were national in scale, resulted in a $5.8 billion reduction in gross domestic product (Wheaton et al., 2005). Extreme weather and climate events impact the health and well-being of Canadians beyond monetary costs, as they frequently involve displacement, injuries and loss of life. For example, the 1998 ice storm led to the greatest number of injuries (945) and 17 800 evacuations (Public Safety Canada, 2005). Unusually heavy rainfall following a period of drought was a contributing factor to the E. coli outbreak in Walkerton, Ontario in 2000 that resulted in seven deaths and thousands of people becoming ill (O 'Connor, 2002).

Increases in temperature and changes in precipitation have been observed across most of Canada over the past century. During the past 50 years (1948-2006; the period for which data are available for both northern and southern Canada), average national temperature has increased 1.3 °C (see Chapter 2; Environment Canada, 2006). This is more than double the increase in mean global surface temperature during the same time interval. Canada is projected to continue to experience greater rates of warming than most other regions of the world throughout the present century (see also Chapter 2; Environment Canada, 2006). The magnitude of changes in climate will vary across the country, with northern regions and the south-central Prairies warming the most (Figure 2). Average annual precipitation is also projected to rise, although increases in evaporation and transpiration by plants in some regions are expected to more than offset increases in annual precipitation, resulting in increased aridity. More frequent heavy precipitation events, less precipitation during the growing season and more precipitation during the winter are also projected for Canada
