Pesticides are used to reduce damage to crops from weeds, rodents, insects and germs.
Though they may have negative effects, pesticides and fertilizers are also vital to human health and safety in many ways, so use them safely to maximize their benefit and limit risk.
Pesticide Problems Pesticides have been linked with deleterious effects on human health and that of the environment.
Children exposed to pesticides have increased rates of leukemia and brain cancer, and pregnant women with exposure have higher miscarriage rates, according to the Canadian Association of Physicians for the Environment.
Pesticides may also damage the lungs and nervous system. In nature, pesticides pollute the air, water and ground.
As a result, plant and animal life may die or become sick and malformed. Benefits of Pesticides The top benefit of pesticides is their effectiveness against pests that would otherwise decimate crops large and small. By controlling insects and rodents, pesticides prevent the spread of disease and protect buildings from termite infestations.
Pesticides also keep the price of clothing and food down by eliminating predators that would destroy crops, raising the cost of things like corn and cotton.
Even surgical instruments and operating rooms are disinfected with pesticides, according to the Environmental Protection Agency.
Fertilizer Drawbacks Though fertilizers have their benefits, there are also downsides to their use, particularly with regard to synthetic fertilizers. Phosphorus from fertilizer can cause algae to accumulate in lakes and ponds, killing fish by robbing them of oxygen.
Fertilizers can also contaminate water with an overabundance of phosphates and nitrates, making it unsafe for consumption. Oxidized nitrogen, a byproduct of synthetic fertilizers, also increases smog, which may be related to higher incidence of respiratory illness and asthma.
The Upside of Fertilizer Fertilizer comes in many forms, from chemical products to old grass clippings. By providing nutrients like nitrogen, fertilizers help plants thrive despite the threat of weeds and disease.
Organic fertilizers, like manure, improve the fertility of soil by feeding microorganisms in the soil, reducing erosion and keeping soil well hydrated. Grass clippings, scattered on the lawn, are a form of fertilizer that provides valuable phosphorus, nitrogen and potassium and can be had for free by mowing the lawn.Mar 07, · Plants for Health All Growing your own crops means that you can use healthier methods to control any pests.
There are all-natural remedies for controlling pests and enriching soil. "Potential Health Effects of Pesticides." Pesticide Education (Penn State Extension), n.d. Web. 1 Mar.
"What is a pyrethroid insecticide? Why Organic: Harmful Effects of Chemical Pesticides Pesticide-based repellents and lawn treatments are becoming things of the past, as safer alternative products begin to surface. These new formulas are every bit as effective as their chemical cousins, but without the negative side effects.
Toxics Action Center is working side by side with communities to: Reduce pesticide use Fight for the right to know who is using chemicals, where, when, how, what pesticides are being used, and why. The report included concerns that pesticide exposure could have links to childhood cancers and developmental disorders based on the group’s review of government health trend data and recent academic research.

Why Organic: Harmful Effects of Chemical Pesticides Pesticide-based repellents and lawn treatments are becoming things of the past, as safer alternative products begin to surface. These new formulas are every bit as effective as their chemical cousins, but without the negative side effects. Each pesticide or pesticide class comes with a specific set of environmental concerns. Such undesirable effects have led many pesticides to be banned, while regulations have limited and/or reduced the use of others. Over time, pesticides have generally become less persistent and more species-specific, reducing their environmental footprint.
Use of excessive pesticide, herbicide and rodenticide — poison used to keep rodents away from plants — may have potentially lethal effects on wildlife.
Researchers have studied the impact of pesticides and rodenticides on wildlife, in particular the weasel-like fisher, in . The investigation of natural products in agriculture is a response to the strong negative environmental impact caused by the massive use of synthetic pesticides (pollution of ecosystems), as well as their effects on the human population (proliferation of diseases, including cancer).
