Summary: Yes worksheet used for Say “No” to BUGS! Or should we?

“Yes” Pesticides

  1. 1) “Without herbicides, the most widely-used class of pesticides in the United States, crop production and yields would drop, pristine habitat would have to be plowed under to accommodate more crop acres, and the additional cultivation would result in more soil erosion” (Leonard Gianessi)
  2. 2) “Herbicides provide more-effective, cheaper control of weeds, with less crop damage, than non-chemical alternatives.” (Leonard Gianessi)
  3. 3) “…pesticides also represent a valuable public health resource, protecting people from debilitating, disfiguring, and often fatal diseases transmitted by insects…” (Jerome Goddard)
  4. 4) “Save Human Lives: Since 1945, DDT and other Insecticides have prevented the premature deaths of at least 7 million people: Malaria, Bubonic Plague.” (Miller)
  5. 5) “Increased Food Supplies: Estimated that pests destroy 37% of potential food for the United State. Losses would be worse without pesticides.” (Miller)
  6. 6) “Work faster and better than alternatives: Control pests at a reasonable cost, long shelf life, easily shipped and applied, and safe when applied properly.” (Miller)
  7. 7) “Health risks insignificant when compared to benefits: at most 1% cancer related deaths are caused by pesticides.” (Miller)
  8. 8) “As time progresses pesticides are becoming safer, and are used at a much lower rate.” (Miller)
  9. 9) “Herbicides can be applied to a larger acreage per day than cultivation or hand weeding. In addition, soil-applied herbicides typically kill weeds as they germinate and continue to remain effective for a few weeks after application. (Brown & Pope)
  10. 10) “Cultivation Cost is reduced or eliminated. Each Cultivation costs between $6 and $7 per acre. Usually, cultivation must be repeated to be effective if it is the sole weed control strategy. (Brown and Pope)
  11. 11) “Farmers applying or purchasing restricted use pesticides must pass a certification exam and maintain proof of competence in the use of pesticides. In 1998, more than 22,500 farmers attended Iowa State University Extension certification training programs on safe and effective pesticide use.” (Brown and Pope)
  12. 12) “Without pesticides, about 1/3 of any crop would be lost to disease, infestation or predation.” In fact, the risk of not using pesticides and other chemicals is far higher than the small and hypothetical risk of using them.” (Berry)
  13. 13) “Chemicals have enabled far more people to have access to inexpensive fresh fruit and vegetables: Studies show that eating more of these improves the chance of defending yourself against diseases – including cancer. The risk of contracting disease due to ingesting pesticide residue, meanwhile, is hypothetical. (Berry)
  14. 14) “By increasing crop yields, pesticides and other agricultural chemicals reduce pressure to convert marginal land to agriculture. So, even though some of this cropland may support less wildlife, there will be more land left for wildlife overall.” (Berry)

Definition of a lens


A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
