Pollution and Plunging Male Fertility

Several reliable studies have confirmed that fertility among men has decreased as a result of pollution.

The average male ejaculation is about three milliliters. This amount of semen can contain between 20 million to 300 million sperm per milliliter semen. To determine the approximate number of sperm per milliliter of semen, technicians must place a drop of semen on a slide and, while looking through a microscope, they count the sperm within a certain sector. Men that have sperm counts below 20 million per milliliter are said to have reduced fertility and those whose counts fall below 5 million are considered sterile.

In 1974, C. M. Kinloch-Nelson and Raymond G. Bunge at the University of Iowa, studied the semen quality of men who had fathered two or more children and were about to undergo vasectomies. Of the 386 fertile men studied, 7% of them had sperm concentrations above 100 million per millimeter and the average concentration was 48 million. When they compared their findings to similar studies done in the thirties, they found that sperm counts had been decreasing for 50 years.

Amazingly, the male fetus begins to produce testosterone as shortly as seven weeks after conception. According to Harvard Health, men’s testosterone levels actually peak around age 17. In fact, testosterone levels usually plateau for a while, and then slowly start to decrease around age 30 and 40. The normal rate of decline is about 1 percent per year after the age of 30. By the time a man reaches 80, his testosterone level will be about half of what it was when he was a young man.

    China is renowned for its nationalism and opposition to the West. It wasn’t until the 1970’s, when Deng Xiaoping allowed other countries into China, that they began their own globalization journey. Even after that huge leap forward, a mixed market economy with trade didn’t really materialize until the 1990’s. The former leader, Mao Zedong had instituted a communist rule. Under Mao’s rule, the people had no voice and no choice. Businesses, temples, school and medical care was governed by Mao.

  • Supply Chain

    1222 Words  | 3 Pages

    Traditionally, marketing, distribution, planning, manufacturing, and the purchasing organizations along the supply chain operated independently. The objectives of these organizational divisions are always different and conflict with each other’s objectives. . Marketing puts a higher emphasis on high customer service and maximum sales dollars conflict with manufacturing and distribution goals. Many manufacturing operations are designed to maximize throughput and lower costs with little consideration for the impact on inventory levels and distribution capabilities. Purchasing contracts are often negotiated with very little information beyond historical buying patterns. The result of these factors is that there is not a single, integrated plan for the organization---there were as many plans as businesses. Clearly, there is a need for a mechanism through which these different functions can be integrated together. Supply chain management is a strategy through which such an integration can be achieved.

    Managing change is an “ongoing process whose objective is to enhance the ability of an organization to participate and respond to developments in its external and internal environments, and to enable employees at all levels to cope with the changes” (Cascio, 2016, p. 6). Change is never easy, but never impossible. It occurs when there is an understanding of the need for change, the vision of where the organization should go, and a commitment to action. Change leaders need to address the question “Why change?” and develop a rationale for the change and a compelling vision of a possible future. “Being dissatisfied with the status quo helps to ready the organization for change” (Cawsey, et al, 2016, p. 106). It is critical to involve every member in the organization, from top to bottom, in the early stage of change to be successful. The goal of the leader is to get each individual to “buy-in” the proposal to get support from

This process of supply chain management (SCM) consists of many activities and information flows such as the procurement of materials, the process of manufacturing and packaging, followed by the storage and warehousing of the finished products before being distributed to retailers for the end user’s consumption (Cooper, Lambert & Pagh 1997; Griffin & Thomas 1996). SCM involves the coordination of the following functions: strategic supplier partnerships, quality of information sharing, management of internal functions and loyal customer relationships (Barbosa-Póvoa, Barros & Blanco 2013).
