In the fields, the pollution can be finding in the crops and in the way of planting. Uses of chemicals products, such as pesticides and fertilizers, can be dangerous for the human and the nature. For humans, because of the contamination that some products, such as pesticides and herbicids (for weed control), can cause when it is apply, by the exposure to it. This products, because their are dangerous for the human health, has to follow rules of application and in restriction quantity (1). And when applied by a person, this has to own special clothes and accessories (like gloves and glasses) to their security, to not be exposure at the toxicity of the substance. But sometimes this safe procedure do not happens. The pesticides find in countries that are developing in commercial agriculture when are used by subsistence farmers, is harmful because they are not familiar with potential injuries and safety procedures (World Health Organization&United Nations Environment Programme, 1990). Causing sickness or developing cancer in the farms, and the chances of cancer incidence is higher in farmers, and persons who works with pesticide application than in general population (Dich.J, 1997).
Another aspect that can cause toxicity to human is the residues of pesticides finding in mostly of food like vegetables, fruits, and grain. And its possible that pesticides is related with the cause of cancer, tumors and others diseases and sickness (Dick.J, 1997). Because of the relationship of residual pesticides and development of diseases, many persons are adopting organics’ foods. Chosen vegetables and fruits that are produced without the addiction of pesticides, and second Christine McCullum-Gómez (2010),list some of common used fruits and vegetabl...

Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).

The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.

...ortation of plants, fruits, vegetables, and animals. Indiscriminate pesticide use kills the good with the bad. Long term and wide spread pesticide use poisons underground water sources, which, in turn, poison plants, animals, and humans. And, finally, by our uninformed actions, new super races of pests continue to evolve and create even greater dangers than the original.
...on due to the limited number and variable results of studies. Several studies discussed in Smith-Spangler et al. (2012) and Crinnion. (2010) have also confirmed higher pesticide residue and contaminants from some conventional produce. Eating organically grown fruits and vegetables does not necessarily provide better quality or highest nutritional quality however consumption of Dirty Dozen from organic section may expose to less chemical residue and contaminant intake. Despite the different farming practices of organic and conventional crops most of the fruits and vegetables appears to be same except some minor difference of vitamin C levels and antioxidant activity which is not statistically significant. Consumer should be encouraged to consume fresh fruits and vegetables and make at least half of their plate consist of fresh produce to gain optimum health benefits.

As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should

The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil, in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the soil was severely damaged from monoculture (The cultivation of a single crop in a defined area).... ... middle of paper ... ...
There are 2.5 billion pounds of pesticides being applied to agricultural products each year in the United States. This is ten times more than was applied forty years ago. It is still unknown as to what type of exact effects these chemicals may have on individuals. Some farmers that have been using pesticides in their fields and developed leukemia are finding that the cause of their disease is from inhaling pesticides. These chemicals are still in use today and most of them have never been tested for the short or long-term effects that they may have on humans.
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.

Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture. For instance, ammonium nitrate used as ammonium nitrate fertilizer”.
