The time taken by the human population to double from 1 billion to 2 billion, from 2 billion to 4 billion and determine the conclusion that can be drawn from the rate of population growth. Concept introduction: Population growth is the rate at which the population grows. It is the speed with which the number of people of a defined location increases. Many factors influence the population growth such as the rate at which people are born, the rate at which people die and the rate at which people emigrate or immigrate from one location to another.

Summary Introduction

To determine:

The time taken by the human population to double from 1 billion to 2 billion, from 2 billion to 4 billion and determine the conclusion that can be drawn from the rate of population growth.

Concept introduction:

Population growth is the rate at which the population grows. It is the speed with which the number of people of a defined location increases. Many factors influence the population growth such as the rate at which people are born, the rate at which people die and the rate at which people emigrate or immigrate from one location to another.

Expert Solution & Answer

Explanation of Solution

With reference to the fig. 49.1 of chapter 49, the time taken to double the population from 1 billion to 2 billion, it took 130 years. That means the rate of population growth was fairly slow. This can be attributed to lack of treatments and vaccines towards various diseases that balanced the rate of births and deaths.

The time taken to double the population from 2 billion to 4 billion, it only took 45 years, which means that the rate of population growth was very rapid than the previous years. This can be attributed to the development in the field of science that helped to achieve relatively low death rates that led to population boom.

The pattern depicted in the graph of fig. 49.1 tells that the rate at which the population grew had increased gradually with time.

Conclusion

The rate of population growth has increased rapidly from the years 1930 to 1975, whereas from the year 1800 to 1930 the population growth rate was very slow.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
