PESTICIDES ON THE ENVIRONMENT AND HUMAN HEALTH 

Pesticide is a mixture of substances used to prevent the growth of weeds, insects and pest. Thus, it is the chemical combination of a herbicides and insecticides. Chemicals have been used to control pest around 4500 years ago. A compound derived from dried flowers of Chrysanthemum cineraria folium has been used as insecticide for over 2000 years. Some parts of the world were using salt or sea water to control weeds. 

Without pesticides, food production would be lower,  supply will also lower and as mankind can?t live for number of days and population increasing rapidly especially in Africa,  hence going to increase  food. Competition in global market is going to be less and developed countries exports would drop leading to shut down of many jobs. Price of farm produce would also increase. 

Upon this benefits, pesticides can be harmful to both the environment and human. When pesticide is sprayed on weeds , small amount of the pesticide will be on target. The rest of the quantity will be off target , the quantity may touch a different species like an ant and others or the environment which may cause injury like genetic disorders and can reduce the life span in the long run. 

Acute health problems may occur in workers that handle pesticides such as abdominal pain,  dizziness, headaches, nausea, vomiting, as well ad skin and eye problem. In China, an estimated half million people are poised by pesticide every year, 500 of whom dies. Insecticides commonly used in bug killers can cause a potentially deadly condition if breathed in. Multi university research team in Toronto concludes, ?people should reduce their exposure to pesticide because of link to serious illness. Results of this study found consistent evidence of  health risks such as cancer, nervous system disease and reproductive problems in people exposed to pesticides. Similar research has linked exposure to pesticides to increased presence of neurological disorders ,childhood leukemia, lymphoma, asthma and more. 

Progressing to organic repellents or logical step to potentially help reduce the chances of disease or disease acceleration.
