Pesticides
Environmental effects
Pesticides are chemicals or biological agents, such as a virus bacterium, antimicrobial or disinfectant, that will incapacitate, kill or otherwise discourage pests but these effects can spread on to affect others that are not intended to be affected such as humans, and vegetation.
The target pests are usually insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes, and microbes that destroy property, cause nuisance, spread disease, or are vectors for disease, but other non-targeted organisms are usually harmed or killed by the pesticides.
How to lessen the harmfulness of pesticides
Some ways you can lessen the harmfulness of pesticides is by
buying locally grown fruits and vegetables.
grow your own fruits and vegetables.
use less toxic pesticides which are less harmful
use alternative methods
Benefits
Pesticides are a good and easy way to remove pests. They do the job correctly and properly. They control pests and plant diseases improving crop/livestock yields and quality.
They also control human/livestock disease vectors saving and reducing suffering human and animal lives and containing diseases geographically.
Monetary benefits are also in effect because for every dollar spent on pesticides 4 times the amount is made on the yield of the crops saved.
Risks
As pesticides are there to cause problem to pest organisms, these problems may spread to other non-pest organisms such as humans, crops and livestock.
Pesticides cause many health problems such as harming workers who get exposed to it.
Environmental effects are also a problem with pesticides as a majority of sprayed insecticides and herbicides reach non-targeted areas.
Pesticides can cause air pollution, water pollution and soil contamination when carried away by the wind.
There are also economical effects since a lot of money is lost due to damages and losses which because of the US government spend $10 billion every year on pesticides.

What are Pesticides?
A pesticide is a chemical which is used commonly to repel, destroy or prevent pests. Pesticides kill pests such as insects, mice, weeds, bacteria and many other pests.



Household pesticide use
Pesticides are commonly used in our everyday lives.
Pesticide products used in our homes are mosquito sprays, rat poison, weed killers,
Alternative for pesticides
Alternative ways to using pesticides can be
Handpicking: Pulling out the weeds wearing gloves.
Collars: By blocking the plant around completely so insects cant go to it.
Nets: Putting nets over your garden so birds and insects stay away, also by putting nets on your doors so insects such as mosquito's don't enter your home.
Alternatives for Pesticides
Alternatives to pesticides include methods of cultivation, use of biological pest controls, genetic engineering, and methods of interfering with insect breeding.
Cultivation: Poly culture (growing multiple types of plants) and trap crops which are used to keep pests from the real crop.
Introduction of other species keep pests away from crops and livestock and include natural predators or parasites to the pest.
Interfering with insects’ reproduction: Sterilizing males of the targeted species and releasing them.
Hot Water: Spray hot water on crops to successfully control insects at a cost about the same as pesticide spraying.
