What is resource? The Effects of Overpopulation & Depletion of Natural Resources.

What is resource?

Ans. Everything in our environment which can be used to satisfy our needs, provided, it is technologically accessible, economically feasible, and culturally acceptable can be termed as a resource.

A resource is a physical material that humans need and value such as land, air, and water. Resources are characterized as renewable or nonrenewable; a renewable resource can replenish itself at the rate it is used, while a nonrenewable resource has a limited supply.


* How does the increase in the human population affect non-renewable resources?
* The Effects of Overpopulation & Depletion of Natural Resources.

Ans.
  • Resource Scarcity: The world's population increased by more than 4 billion people during the 20th century. Although population growth rates are declining in several parts of the world, the population continues to grow and tax natural resources. In areas of tremendous population growth, fossil fuels, timber, water, and arable land can become scarce because of overconsumption and degradation. Resource scarcity has several consequences, including the forced migration of people. In contrast, resource scarcity often leads to technological innovations that find more efficient uses for resources.
  • Rising Prices: Food, fuel, and energy prices rise when natural resources become scarce. A growing population means growing demand for resources. If demand rises too quickly, resource scarcity results and causes prices to rise for several reasons. Nonrenewable resources, including fossil fuels, cannot be replaced, so prices increase when supply dwindles. Even renewable resources, including timber, can increase in price if they need to be shipped long distances to reach areas where natural resources have been depleted.
  • Pollution and Climate Change: People's consumption of energy for transportation, heat, food production, and other activities generates air, land, and water pollution. More people means more pollution, which can exacerbate the depletion of natural resources. For example, when fossil fuels are burned to generate power, carbon dioxide is released. This greenhouse gas traps heat in the atmosphere and contributes to climate change, a process that affects weather patterns, water resources, and the survival of animals and plants many depend on as food sources. Several industrial processes release harmful chemicals into the air and water as well.
  • Water Shortages: In some areas of rapid population growth, such as sub-Saharan Africa, access to clean water is not guaranteed. When infrastructure development cannot keep up with population growth, water shortages and sanitation issues can occur. Almost 1 billion people lack access to clean water and more than twice that many do not have toilets. (see reference 6) Fecal contamination is a major cause of disease; water-related sickness kills a child every 21 seconds. People in impoverished, densely populated areas often spend more money and time accessing clean water than people living in developed areas.

Function Keys Shortcuts

Function Keys Shortcuts (F1 - F12) (Function Keys) F1 It is used to open the help window in almost all programs. Also used to enter BIOS or CMOS Some computers allow you to enter BIOS setup using different keys like F2, F10, Delete, Esc. Pressing Window + F1 will open the Microsoft Windows Help and Support Center. F2 In Microsoft Windows, it is used to rename an icon , file , or folder that the user selects. In Microsoft Excel, the F2 key allows you to edit the selected cell in the Excel sheet. In Microsoft Word, pressing Ctrl+F2 will open the print preview window and Alt+Ctrl+F2 will open the new file or document. In addition, it is also used to enter the CMOS setup. F3 It is mainly used to open a search function for many programs. At the MS-DOS or Windows command line, it gives users the option to repeat the last command entered. In Microsoft Word, if you press Shift + F3 , it allows you to change the selected text from uppercase to lowercase or a capital letter at the beginni...

All About Microservices Architecture

All About Microservices Architecture **Microservices Architecture** is an approach to software development where a large application is broken down into smaller, independent services that can operate and be deployed independently. Instead of building a monolithic application, which is a single, tightly-integrated unit, microservices architecture divides the functionality into separate services that communicate with each other through well-defined APIs (Application Programming Interfaces). Key characteristics of microservices architecture include: 1. **Modularity:** Each microservice represents a specific business capability and can be developed, deployed, and scaled independently. 2. **Independence:** Microservices are autonomous, meaning they can be developed, deployed, and updated without affecting the entire system. This independence allows for faster development cycles. 3. **Scalability:** Since each service is independent, you can scale only the specific microservices that require...

Photo Composition

Rules are made to be broken but are also made for a reason. Our ‘go to’ is the widely known ‘rule of thirds’ and is considered in the majority of our intentional compositions. But what other compositions do we use? 1 - Golden Spiral : Based on the Fibonacci numbers, this composition uses arcs infinitely resembling a spiral shape, which can be used to create balanced and aesthetically pleasing photos. 2 - Cross : A simple but harmonious composition using two lines, creating a midsection crosshair with the subject in the center of the frame. 3 - Tunnel : Similar to ‘leading lines’ tunnel composition is used to draw your eye to a subject using depth. 4 - L Shape : The L-shape composition appears when the elements create the “L” shape which can be (and often is) multiplied. The static horizontal and vertical lines this kind of composition presents create the feeling of rest, stillness, and harmony. 5 - S Curve : The curved lines in an S-curve composition add a sense of movement to an other...
