Geography Task 111- QUIZ

1.      What is the bio fabrication technique? Do you think it is a viable environmental strategy? Why or why not? (7 points)

            Bio-fabrication means making complex biological products from raw materials like living cells, biomaterials, and molecules. Bio fabrication is a viable environmental strategy because it can make structures more like the complexity and variety of tissues and organs than the regenerative medicine therapies available. In the field of regenerative medicine, this could be a big step forward. These structures could be used either to heal damaged tissue or as 3D models in a lab dish. The field of bio-fabrication is growing and changing, and scientists from many different areas of study are getting involved. This shows how important it is to keep terms consistent as the field develops and grows.

2.       Discuss the connection between environmental injustice and locating waste. (7 points)

            To degrade the environment while also excluding some people or communities is what is known as “environmental injustice.” The contamination of drinking water and subsequent health problems in a community is a common result of a company’s pollution of local water supplies. However, locating waste includes everything from waste generation through disposal. Managing waste includes not just the obvious tasks of picking up trash and getting rid of it but also keeping tabs on and controlling the laws, technology, and economic systems that pertain to garbage. Constantly policing compliance with environmental statutes also falls under this heading.






3.      In the picture, identify and describe as many forms of energy as you can. (7 points)

ü  Radiant energy - The Sun is responsible for the emission of a significant quantity of radiant energy, which arrives at Earth in the form of light.

ü  Electromagnetic energy – From the photo all of the energy from the sun that gets to Earth is in the form of solar radiation. An electromagnetic radiation spectrum is a big group of different types of energy, and solar radiation is one of its many parts.

ü  Chemical energy - Light from the sun is transformed into the chemical energy that plants may use for growth and life through a process called photosynthesis.

ü  Nuclear energy - The nuclear fusion process is the source of all the energy coming from the sun, including both light energy and heat energy. The process that generates sunlight is referred to as proton-proton fusion. The method of nuclear fusion that occurs on the inside of the sun is referred to as proton-proton fusion. With a bulk density of

ü  Mechanical energy – From the photo, the movement of the bee is regarded as mechanical energy. Mechanical energy can be either the energy of movement or the energy of something that is moving. All living things and a large number of systems need mechanical energy to work.

4.      True or False: Contamination rates for residential recycling is minimal across all provinces in Canada.

False - Annually, Canadians generate more than 3 million tons of plastic trash. There is just a 9% recycling rate, with the rest going to landfills, incinerators, or the environment. Our wildlife, rivers, lakes, and oceans are all at risk from the plastic garbage and marine litter that we generate. Canada has a special obligation and opportunity to address this problem because it possesses the longest coastline and one-fourth of the world’s freshwater.

5.      Describe some of the challenges with plastic waste and micro plastics? (7 points)

            The issue with plastic waste and micro plastics is that, like plastic products of any size, they do not quickly break down into molecules that are not harmful. This is a concern since micro plastics are especially problematic. Plastics can remain in the environment for hundreds of years or even thousands of years before decomposing, during which time they wreak havoc on the natural world. Microplastics can be seen in the sand at beaches as very little particles of plastic in a variety of colours. Microplastic pollution is a common problem in the oceans, and marine species frequently ingest it.

6.      Regarding soils, what does “bulk density” mean and why is it important? (7 points)

            The term “bulk density” refers to the amount of mass that may be packed into a given volume of soil. The mass or weight of an amount of soil contained in a certain volume is represented by the bulk density of the soil. Therefore, knowing the bulk density of the soil is significant since it shows how much mass or weight is contained in the soil. The bulk density of the soil is what ultimately decides the infiltration rate, the available water capacity, the soil porosity, the rooting depth or limitations, the soil microorganism activity, the root proliferation, and the availability of nutrients. Soils with a bulk density of more than 1.6 grams per cubic centimetre often act as a barrier to the growth of the plant’s roots. Both increasing depth and compacting soil can potentially increase the bulk density of the material. Sandier soils tend to have larger bulk densities than other types of soils.





7.      Calculation (15 points):

a.                  Diameter at breast height (DBH; in meters)


116cm=2 ×22/7 ×R

116cm= (44/7) R

116cm× (7/44) =R


Diameter =2R

Diameter = (203/11) ×2

Diameter= 406/11

             =   73.8182cm

b.                  Basal area (in square meters)

Area of a base= πr2

            =22/7 × (203/11)2



1070.3636/10000* 1m2

=0.107036 m2

c.                   Merchantable volume (in cubic meters) (note: assume a Form Factor of 0.42)

Volume = Basal Area × Height

             =0.107036 m2× 20.3m

             =7,044.1 m3


8.       Calculation 10 points

a.                  Soil bulk density (in grams per cubic centimeter)

Density =Mass / Volume

             Mass = 18.6g

              Volume = 22/7× (1.65cm)2×5.5 cm


Density =18.6g / 47.0603cm3


b.                  Particle density (in grams per cubic centimeter)

Displaced 14ml of water

1ml= 0.001 liters

14ml= (14* 0.001) = 0.014 liters

1 litre = 1000 cm3

therefore 0.014 litres = 14 cm3 = volume

Density = mass/volume =18.6g/14cm3

=1.32857 g/cm3

c.                   Porosity (as a percentage)

Porosity = void volume / total volume

              =14 cm3/47.0603 cm3



9.      Calculation;

a.                  Gross pile volume.

V = l × w × h

    =10.5 ×7.7 × 6.2

= 501.27cm3                    

b.                  Net pile volume (in cubic meters)

         Net pile volume = 501.27cm3   ×20/100 packing ratio

                                = 100.24 cm3               

10.  What are some benefits and challenges to “willingness to pay” method? Do you think this is a useful environmental strategy? (7 points)

Willingness to pay leads to better segmentation. It is essential because it allows for more accurate segmentation of customers based on demographics, location, frequency, retention, income, purpose, and other factors. Willingness to pay has also improved market understanding. It helps one determine the competitive edge one has by researching and analyzing prices. Because you know how the market works, you can ensure everything goes smoothly. Recent studies show that customers are becoming more price-conscious because prices are going up and their incomes are going down.

Zero bids can result if respondents say they are unwilling to pay at all, which is a disadvantage. Extrapolating errors in declared willingness to pay by individuals can lead to substantial mistakes in the population. These inflated appraisals, sometimes known as “rubber money,” pose a threat because interest groups and other stakeholders may use them to sway decisions away from being objective and well-informed.

11.   True or False: Japanese knotweed (Fallopia japonica) is a rare and protected plant species here in Canada.


12.   Do you consider yourself to be a pessimist or an optimist about the future of the world’s environments?

I consider myself an optimist about the future of the world’s environment, mainly because concerns over the effects of climate change have finally reached an all-time high among the general public. The climate problem and its immediate and potential repercussions are a source of concern for an increasing number of people in Canada. On stages throughout the world, environmental justice is receiving recognition. Michael Regan, the current administrator of the World Environmental Protection Agency, has made the advancement of environmental justice one of his agency’s highest priorities. The supermarkets are concluding that there is no need to wrap oranges in plastic before selling them to customers. More than ninety nations have implemented or are implementing restrictions such as bans or taxes on single-use plastic bags and other products made of plastic. The cost of using renewable energy sources decreases as their adoption rate increases. In the past ten years, the cost of building wind and solar power plants has reduced by 70 percent and 89 percent, respectively. The demand for only renewable energy sources increased throughout the pandemic, making them the only type of energy source for which demand rose.

The concept of indigenous sovereignty is gaining traction. The indigenous sovereignty movement has recently received some of the attention that has been long overdue for it to receive. Indigenous groups throughout the world celebrated several victories in 2021, whether those victories came in the form of regaining control of their land or of government institutions beginning to recognize the benefits of Indigenous land management. In a world where bad news seems synonymous with news, there is a great deal of value in looking for the good. As individuals who are concerned about the environment, it is indeed very much crucial that success has been gained by the movement for them to motivate and urge us further in our efforts.
