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.

Schedule in DBMS

Schedule A series of operation from one transaction to another transaction is known as schedule. It is used to preserve the order of the operation in each of the individual transaction. 1. Serial Schedule The serial schedule is a type of schedule where one transaction is executed completely before starting another transaction. In the serial schedule, when the first transaction completes its cycle, then the next transaction is executed. For example: Suppose there are two transactions T1 and T2 which have some operations. If it has no interleaving of operations, then there are the following two possible outcomes: Execute all the operations of T1 which was followed by all the operations of T2.  Execute all the operations of T1 which was followed by all the operations of T2.  In the given (a) figure, Schedule A shows the serial schedule where T1 followed by T2. In the given (b) figure, Schedule B shows the serial schedule where T2 followed by T1. 2. Non-serial Schedule If interle...

DBMS Keys

DBMS Keys KEYS in DBMS is an attribute or set of attributes which helps you to identify a row (tuple) uniquely in a relation(table). They allow you to find the relation between two tables. Keys help you uniquely identify a row in a table by a combination of one or more columns in that table. Key is also helpful for finding unique record or row from the table. Database key is also helpful for finding unique record or row from the table. Example: Employee ID FirstName LastName 11 Andrew Johnson 22 Tom Wood 33 Alex Hale In the above-given example, employee ID is a primary key because it uniquely identifies an employee record. In this table, no other employee can have the same employee ID. Here are some reasons for using sql key in the DBMS system. Keys help you to identify any row of data in a table. In a real-world application, a table could contain thousands of records. Moreover, the records could be duplicated. Keys in RDBMS ensure that you can uniquely identify a table record despite ...
