These alterations are done through the application of incredibly defined genetic manufacturing techniques that have been discovered by scientists. Generally, the objective of modifying food genetically is to make them attractive and unique thus being able to impress the customers.

The incredible scale of this loss has led to significant changes throughout many parts of the world, and in recent years these changes have been accelerating. Deforestation occurs primarily as a result of: And also, to a degree, due to large scale war — throughout history fire has often been used as a way to deprive enemy populations of necessary resources.

Many of the areas of the world that were deforested thousands of years ago remain as severely degraded wastelands or deserts today. Deforestation Effects, Causes, And Examples: A Top 10 List 1. Agriculture Agriculture is one of the primary drivers of deforestation — both in modern times and in ancient times.

The vast old-growth forests that once covered much of the world have largely been cut and burned down because of agriculture.

Even the most efficient agricultural systems and practices inevitably lead to nutrient loss unless supplemented with fertilizer brought in from elsewhere — this nutrient-loss is especially pronounced with GMO genetically modified food agriculture.

And this, along with the soil erosion that accompanies the loss of large vegetation, further contributes to the soil erosion and desertification that seems to almost inevitably follow deforestation in the long term.

Population Growth And Expansion While agriculture is often the direct cause of deforestation, growing and expanding populations are often the driver. Such large population numbers and densities make people very dependent upon agriculture for survival, and also, importantly, dependant upon expansion.

With increased population numbers also comes increased urbanization — which brings with it further impetus for deforestation, and also a number of other negative influences on the surrounding areas via various forms of pollution.

As large populations often quickly use up all of the resources located near them, they almost always become dependent upon expansion in order to continue fueling their infrastructure — this continues until the reliance on distant, far-off resources becomes too burdensome and inefficient, and the civilization collapses or retracts.

Western Europe experienced significant deforestation from around to as a result of the then rapidly expanding human population.

The large industries of the day — the building of wooden sailing ships by European naval powers, colonization and resource-plunder dependent on ships, slave-trade and other sea-based trade — largely consumed and used up the forest resources of Europe. The newly empowered resource producing regions often then follows the same trajectory.

Desertification Effects, Causes, and Examples. Most of the desertification that these civilizations experienced was as a result of agriculture, deforestation, and the associated changes in aridity and the climate.

As these lands are cultivated the limited nutrients that are available in them are quickly depleted. Often times the land is also improperly irrigated — leading to salty soils, and emptied aquifers. As a side note, the Sahara Desert is currently expanding south at a rate of up to 48 kilometers per year.

And is well known for its large stone monuments, called moai. Based on current evidence, the island was likely settled by its current Polynesian inhabitants around CE, give or take a few hundred years. Subsequently, agricultural failures occurred, and, also, the ability to build seaworthy ships was lost.

The final disappearance of the trees on the island seems to coincide exactly with the large-scale decline of its civilization sometime around the 17th or 18th century. The archeological record clearly shows that the current state of the island is vastly different from what it was at the time of its settlement.

Before settlement, the island was nearly entirely forest, with many species of trees that are now extinct there — several of which reached heights of over 50 feet. After resources shortages started to begin the population on the island plummeted to around 2,—3, — from a previous high of approximately 15, It was during this time of crisis that 21 different species of trees, and all of the species of land-birds became extinct.The issue of genetically modified organisms is drawing unprecedented media attention due to its potential of bringing about fundamental changes in the genetic make up of living beings.

Following paragraphs throw some light on this controversial subject. Jul 24,  · In the very short time since GMO foods were first introduced, they have tainted ecosystems, created financial strains for farmers, and introduced unnatural elements into the local, national, and global food supply.
