Human Population Growth

Buy custom Human Population Growth essay

The world witnessed a massive growth in human population in the 20th century allaying fears that the world could hit its carrying capacity sooner than ever anticipated. With the earth’s population currently estimated at seven billion, this eventuality is becoming even more probable. This has triggered debates and discussions on the likely impact of the earth’s fast growing population on human life and other populations. Uncontrolled population growth has contributed to loss of land productivity, depletion of natural resources and consequently famine occasioned by the inability of land to support food production (Gausset, Whyte & Birch-Thomsen, 2005). The human population explosion evident in many parts of the world has also impacted on the habitats of other populations and ion biodiversity (Edward, 2001). With many wild habitats being destroyed by man in his effort to find more land to settle the growing population many wild animals have been put on the brink of extinction as their natural homes are invaded. This may eventually lead to the alteration of our biodiversity in ways that may have catastrophic effects ion the face of the earth. Man therefore has an obligation to come to the rescue of our biodiversity. This they can do by advocating for a studied approach to natural resource exploitation and the use of such resources. It is only in so doing that we can save mother earth from ultimate destruction.

Memory and manipulation

In the article, Sasha Abramsky writes about Dr. Elizabeth Loftus, a celebrated psychologist who explores how memory loss may affect witness evidence in law. Dr. Loftus carries out a research on the Jane Doe case to illustrate this. Her research reveals that contrary to the allegations made by Doe, then only six years of age, and reiterated by her eleven years later, the girl was never abused by her mother. She also cites cases where eyewitness evidence has led to the wrongfully convictions only for the victims to be acquitted years later after being cleared of the crimes by   DNA evidence.  She is categorical that memory can lie (Sasha’ 2004).  This, she says is particularly so when we are prompted in a particular direction by individuals we trust. She concludes that eye-witness testimony is subject to faults as a result of a possible memory loss. As such it is important that the possibility of such memory loss is dispensed with before such evidence is deemed credible.
