Phosphorus is a critical nutrient for sustaining plant and animal life. Phosphorus for crop fertilizer is mined from certain rock deposits, primarily in the United States, China, Morocco, and Tunisia. Examine the plot below of worldwide production of mined rock phosphorus (megatons, MT), since 1900 (Scholz and Wellmer, Global Environmental Change, 2013, 23 (1), 11-27). Answer the following questions based on your analysis of the phosphorus plot: a. What resource production model is appropriate for the world production of mined rock phosphorus? Why? b. When do you estimate that peak rock phosphate production occurs? At what peak production? c. Based on your production model, what will be the total amount (MT) of rock phosphorus mined worldwide? Use the following assumptions, as appropriate, for your production model: r= 1.0 %; o = 25 years.

Modern day business organisations are expected to not only be profitable but to be sustainable as well. This implies that the business cannot only look internally, that it should also consider environmental and social sustainability. In order to achieve sustainability overall, businesses have to include environmental accounting and environmental economics as part of their sustainable management strategies.Indications are that the jewellery market is growing at a stable pace, both locally and globally. This is a great opportunity for a business like Katie Valentine Collections to grow the business across the globe. However, growing the business will come with key responsibilities for the business, not only for internal stakeholders, but also for external stakeholders as well as the natural environment.Drawing from all the articles above, write an essay of a minimum of 1 000 and a maximum of 1 200 words (1 ½ - 2 pages), in which you address the following:1.

FAO-Funded Aquaponics Project Launched In BarbadosBarbados GIS – The United Nations Food and Agriculture Organization (FAO) hascollaborated with the Ministry of Maritime Affairs and the Blue Economy, and local businessAdams Aquafarms, on a project to train persons in aquaponics.Aquaponics is a sustainable way of integrating land-based fish farming with plant production.Both are placed in a tank, and the set up allows for them to coexist, with the waste producedby the fish fertilizing the plants, while the plants purify the water for the fish.The training, funded by the FAO, will take place at a demonstration facility, located atAdams Aquafarms, Hopewell, St. Thomas. The FAO is currently targeting 30 entrepreneursand 10 teachers.Minister of Maritime Affairs and the Blue Economy, Kirk Humphrey, believes the projectwill be “transformative”, as it has the potential to empower Barbadians.“In aquaponics, you have the opportunity to have, at the same time, multiple sources ofincome [because]…
Sustainable Competitive Advantage In general, capabilities and resources become strengths with the potential to create a competitive advantage if the following conditions are met: The resources or capabilities are valuable. They allow the firm to exploit external opportunities and/or neutralise external threats. If a firm’s resource or capability allows exploitation of opportunities or neutralisation of threats then it is considered a strength. 2.The resources or capabilities are unique. If only one or a small group of organisations possess a valuable resource or capability, then that resource or capability may be a source of competitive advantage. If numerous organisations possess a particular resource or capability, then the situation is described as competitive parity – no company has the advantage. 3.The organisation must be suited to the exploitation of the resource or capability. This means that the structure and systems of the firm are appropriate for taking advantage of the…

Describe the difference between Non-Renewable and Renewable resources using specific examples to illustrate both. In MDCs, government policy seeks to increase the use of renewable energy, but some non-renewables, such as Lithium, are still important to the global economy. Describe and discuss the distribution of non-renewable strategic minerals and explain why they are ‘Strategic’. Why are these minerals so important when the world is aiming to minimize the use of non-renewables? Use TWO examples to illustrate your answer. (Chapter 12)
Dawn and Richard are managers at a multinational corporation. They are having a conversation about the impacts of globalization. “Globalization is a positive economic force for all countries,” Dawn argues. “If products are being produced at lower prices around the world, we’ll pay lower prices for them here in the United States.” She adds that people worldwide are essentially economic actors, aiming to maximize purchasing power utility by trying to find the highest quality product, irrespective of national origin, for the lowest possible price. “Those lower prices come at a cost,” Richard retorts. “While we may be better off as a result of globalization, poorer countries pay the brunt of the costs. Poor countries must eliminate environmental regulations in order to attract foreign companies, resulting in health problems for citizens in those countries. Furthermore, those new jobs overseas replace American jobs here at home. That harms our economy and contributes to high unemployment.…
