illegal logging activities throughout the country and strip mining for gems in the western region along the border with Thailand have resulted in habitat loss and declining biodiversity ( in particular, destruction of mangrove swamps threatens natural fisheries ); soil erosion ; in rural areas, most of the population does not have access to potable water ; declining fish stocks because of illegal fishing and overfishing

Undisturbed forests have a very low rate of soil loss, approximately 2 metric tons per square kilometer ( 6 short tons per square mile ).

deforestation ; desertification ; soil erosion ; overgrazing ; loss of infrastructure from civil warfare ; ash contamination from recent eruption of the Nabro Volcano.

Excessive erosion causes problems such as desertification, decreases in agricultural productivity due to land degradation, sedimentation of waterways, and ecological collapse due to loss of the nutrient rich upper soil layers.

For example, in the Great Plains, it is estimated that wind erosion soil loss can be as much as 6100 times greater in drought years, than in wet years.

Globally one of the largest contributors to erosive soil loss in the year 2006 is the slash and burn treatment of tropical forests.

The action of microbes on organic matter and minerals may free nutrients for use, sequester them, or cause their loss from the soil by their volitalization to gasses or by leaching upon their conversion to soluble forms.

The group threatened to leave samples of the soil " at appropriate points that will ensure the rapid loss of indifference of the government and the equally rapid education of the general public ".

* Percentage residue is used to compare tillage systems because the amount of crop residue affects the soil loss due to erosion.

In areas that are highly susceptible to erosion, farm management practices such as zero and reduced tillage can be supplemented with specific crop rotation methods to reduce raindrop impact, sediment detachment, sediment transport, surface runoff, and soil loss.

Protection against soil loss is maximized with rotation methods that leave the greatest mass of crop stubble ( plant residue left after harvest ) on top of the soil.

Such management practices that succeed in retaining suitable soil cover in areas under fallow will ultimately reduce soil loss.

FDA label information for Vidaza, a formulation of 5-azacitidine ( an unmethylatable analog of cytidine that causes hypomethylation when incorporated into DNA ) states that " men should be advised not to father a child " while using the drug, citing evidence in treated male mice of reduced fertility, increased embryo loss, and abnormal embryo development .< ref >

It also puts forward views on the causes of rapid loss or gain of fertility upon the earth.

As a result, much of the success of modern systems depends on the development and maintenance of soil fertility through the specific provision of nutrients when they are depleted ; of machine power and technology to create soil conditions necessary to promote plant growth with minimal disturbance and minimal soil loss ; of the use of improved genetics for crops and livestock to enhance yields, quality and reliability ; and, on modern genetic and other techniques to protect plants and livestock from losses to competing plants, diseases, drought insects and other threats.

Typically, ecotypes exhibit phenotypic differences ( such as in morphology or physiology ) stemming from environmental heterogeneity and are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.

Health effects attributed to endocrine disrupting compounds include a range of reproductive problems ( reduced fertility, male and female reproductive tract abnormalities, and skewed male / female sex ratios, loss of fetus, menstrual problems ); changes in hormone levels ; early puberty ; brain and behavior problems ; impaired immune functions ; and various cancers.

Due to increasing population density, however, they use the land almost continuously today ; the loss in fertility is partially countered through extensive use of fertilisers and manure.

Because growth rate and fertility are very low, these snails are especially vulnerable to loss of individuals through human collection, through predation, or because of other disturbances.

A common example used in undergraduate education is the determination of the amount of water in a hydrate by heating the sample to remove the water such that the difference in weight is due to the loss of water.

The primary benefits over rifled barrels is reduced barrel wear, longer ranges that can be achieved ( due to the reduced loss of energy to friction and gas escaping around the projectile via the rifling ) and larger explosive cores for a given caliber artillery due to less metal needing to be used to form the case of the projectile because of less force applied to the shell from the non-rifled sides of the barrel of smooth bore guns.

Reasons for their decline include hunting for hide, horns and meat by the local peoples and loss of habitat due to the advancement of settlement.

Assyria lasted a few more years after the loss of its fortress, but attempts by Egyptian Pharaoh Neco II to rally the Assyrians failed due to opposition from king Josiah of Judah, and it seemed to be all over by 609 BC.

On more modern canals, " guard locks " or gates were sometimes placed to allow a section of canal to be quickly closed off, either for maintenance, or to prevent a major loss of water due to a canal breach.

One of the main theses of casuists was the necessity to adapt the rigorous morals of the Early Fathers of Christianity to modern morals, which led in some extreme cases to justify what Innocent XI later called " laxist moral " ( i. e. justification of usury, homicide, regicide, lying through " mental reservation ", adultery and loss of virginity before marriage, etc .— all due cases registered by Pascal in the Provincial Letters ).
