We should not use pesticides, especially pesticides like DDT that could harm organism life. Pesticide, as long as it is organic is okay. Organic pesticide give no harm towards organisms and environment. Even though we have to be careful with the dose of our organic pesticides, it is still safer than non-organic pesticides. My own organic pesticide made from a very sour liquid and I was so surprised that I know from my teacher that it could burn down the leaves. So, I only pour a little of that liquid and mixed it with proper amount of water to reduce the acidity value.
The effects of pesticides upon human are actually depends on each pesticides toxicity rate and how each human could resist those toxic.
Pesticides can enter the human body through inhalation of aerosols, dust and vapor that contain pesticides; through oral exposure by consuming food and water; and through dermal exposure by direct contact of pesticides with skin. Pesticides are sprayed onto food, especially fruits and vegetables, they secrete into soils and groundwater which can end up in drinking water, and pesticide spray can drift and pollute the air.
The effects of pesticides on human health are more harmful based on the toxicity of the chemical and the length and magnitude of exposure. Farm workers and their families experience the greatest exposure to agricultural pesticides through direct contact with the chemicals. But every human contains a percentage of pesticides found in fat samples in their body. Children are most susceptible and sensitive to pesticides due to their small size and underdevelopment. The chemicals can bioaccumulate in the body over time.
Exposure to pesticides can range from mild skin irritation to birth defects, tumors, genetic changes, blood and nerve disorders, endocrine disruption, and even coma or death.
