Increasing population density, urbanization, industrialization and other development schemes, are exerting ever increasing pressure on the carrying capacity of land and resources, leading in particular to a rapid rate of deforestation, expanding desertification in some countries, and the near extinction of some wildlife species. Physical factors such as earthquakes, hurricanes, monsoon rains and the immense problem of poverty in some countries accelerate the decline in environmental resources.

Despite the availability of scientific methods in agriculture and animal husbandry, present methods of farming tend to yield a much smaller percentage than is potentially feasible with proper crop rotation, more plant varieties, plant nutrients, fertilisers and proper pest control. In many villages in the developing nations only a little over 50% of the arable land is used for agricultural production, which leaves much land uncultivated that could possibly produce profitable crops. In many rural areas, even with plentiful rainfall, dependence on subsistence farming has resulted in only short-range agricultural planning.

With existing traditional farming methods, it is difficult to meet family food requirements. Continuous soil erosion, limited means of fertilization, inadequately cultivated fields, and uncontrolled grazing practices all work to create minimally-productive farmland. Farmers tend to have little experience in poultry-keeping or in mechanized farming methods because of the inaccessibility of training centres where they might learn modern farming methods.

Because of the low-yield farming methods, much of the village employment is cyclical rather than continual. Sometimes residents are blocked by outside ownership which controls their markets and brings minimal economic returns to the farmer. Land cultivation is often done with animal powered-single furrow ploughs; the farmers depend on regular rains to supply water where there is no irrigation system. Chickens, pigs, goats, cows, geese, ducks and rabbits live in family yards and are raised for home consumption only - these animals freely forage for food throughout a village since there is usually no common grazing land. Without proper upbreeding of present stock and a larger variety of animals, profitable animal husbandry is not possible.

The terms "dermatitis" and "eczema" are often used interchangeably. Eczema a superficial inflammatory disease of the skin which causes it to become red, itchy and scaly; it accounts for about one-half of all cases of skin disease. It can be "acute" or "chronic" or both. Acute eczema refers to a rapidly evolving red rash which may be blistered and swollen. Chronic dermatitis refers to a longstanding irritable area. It is often darker than the surrounding skin, thickened and much scratched and often called 'dermatitis'. Eczema can also be due to other naturally occurring environmental factors: cold or hot weather and exposure to the sun. It results from a variety of different causes and has various patterns. 

The consumption of animal flesh (whether meat, fowl or fish) or the use of animal products (leather goods, products of bone-processing, eggs and cheese) is unethical, unaesthetic, uneconomic, and without nutritional justification. It may be considered unethical because human beings should not needlessly kill sentient animals. The consumption of animal flesh is not the most economic method of obtaining the highest yield of nutritional products from agricultural land. The economic and social costs of meat consumption include hugely inefficient use of freshwater and land, heavy pollution from livestock faeces, rising rates of heart disease and other degenerative illnesses and spreading destruction of forests.

Sin is a religious issue defined in different ways among different traditions. Within the Christian traditions sin is any word or deed or thought against the eternal law. In addition it includes violations of God's will that do not count as moral offences, i.e. idolatry. It is indifference or opposition to the will of God, the refusal of faith and love. It is an explicit or implicit claim to live independently of God, to put something else, be it the world or self, in His place. Paul Tillich states that sin, as opposed to sins, is the all prevailing problem of one's life. It is a state of existence before it is an act. It is simultaneously willed and fated separation from self, others and the Ground of Being.
