Soil Pollution The process of contamination of the land surface of the earth is referred to as land pollution. It results from human activities that cause imbalance in nature. Dumping human and industrial waste harmful agricultural practices and exposing the land to harmful chemicals leads to the pollution of land. We speak of water and air pollution and rarely even think of the adverse effects of land pollution. Let me share with you some of the important facts about land pollution. Land

Water and Soil Protection Soil Contamination: Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo (a) pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals.

When I was researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water.” I am not sure about you

“Sons-of-the-Soil” and Local Insurgencies ABSTRACT One explanation for localized armed conflicts is competition between the original inhabitants of an area and more recent settlers‚ including both migrants from the same country and from abroad. As of yet‚ this explanation has not been thoroughly scrutinized‚ partly due to the lack of disaggregated data on violence needed to properly examine the hypothesis. Hence‚ this paper applies the idea of such “sons-of-the-soil” dynamics to

Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and

populated regions are a significant threat to people‚ property‚ and agriculture. The danger is mostly from fast-moving‚ hot flows of explosively erupted materials‚ falling ash‚ and highly destructive lava flows and volcanic debris flows. In addition‚ explosive eruptions‚ even from volcanoes in unpopulated regions‚ can eject ash high into the atmosphere‚ creating drifting volcanic ash clouds that pose a serious hazard to airplanes.
