Pesticides

It’s always fun to get roses on Valentines Day! But who would ever think when buying roses that they have been sprayed, rinsed and dipped in “a battery of potentially lethal chemicals”.

Does anybody remember that movie we watched last year in Mr. Slajert’s class called “Maria Full of Grace?” Maria worked in that crowded greenhouse cutting roses all day long and dipping them in chemicals. The working conditions were awful and she ended up losing her job. That’s how it really is in Bogota, Colombia. Working with roses provides an alternative to selling cocane, which many end up doing (like Maria in the movie) However, this so-called “positive”alternative hurts workers’ health and Columbia’s environment.

Pesticide usage is a huge problem in Bogota, Columbia. Almost all of the chemicals used for roses are classified as “extremely” or “highly” toxic by the World Health Organization. Making the problem worse, unlike the U.S., Columbia has no government regulations about pesticide use inside greenhouses, where toxicity levels tend to rise. On Nov. 25, 2003, 200 workers at Flores Aposentos were hospitalized after fainting and developing sores inside their mouths. The company was only fined $5,770 for this mass poisoning.

TO GO WITH STORY SLUGGED COLOMBIA TOXIC FLOWERS- A worker cut roses at the Inversiones Morcote flower farm in Bogota, Monday, Jan. 22, 2007. Inversiones Morcote is certified by Germany-based FLO-Cert GmbH for pursuing socially and environmentally sustainable agricultural practices. Some US consumer advocates complain that Colombia’s cut-flower industry, the second largest in the world, is ignoring market trends and relying too heavily on the use of pesticides.

Some of us wrote about pesticides as an indoor air pollutant for our indoor air quality assignment. The EPA lists this under health effects:

Irritation to eye, nose, and throat; damage to central nervous system and kidney; increased risk of cancer. Symptoms may include headache, dizziness, muscular weakness, and nausea. Chronic exposure to some pesticides can result in damage to the liver, kidneys, endocrine and nervous systems, as well as an increased risk of cancer.

Links between chemicals and individual illnesses are hard to prove because chronic pesticide exposure has not been studied in enough detail. However, researchers have found some disturbing information:The Harvard School of Public Health examined 72 children ages 7-8 in a flower-growing region of Ecuador whose mothers were exposed to pesticides during pregnancy and found they had developmental delays of up to four years on aptitude tests. Philippe Grandjean, who led the Harvard study published last year, said “Every time we look, we’re finding out these pesticides are more dangerous than we ever thought before and more toxic at lower levels.” For example, a woman named Carmen Orjuela began suffering dizzy spells falls while working at a flower farm in Bogota, Columbia. During the season of Valentine’s Day, she said her employer forced workers to enter greenhouses only a half-hour after they had been fumigated. (It is recommended that workers wait 24 hours before entering greenhouses sprayed with toxic pesticides) Carmen Orjuela said that those who refused to enter the greenhouse were told they could leave because 20 people were waiting outside to take their job. A study from Colombia’s National University confirmed that Carmen Orjuela’s illness was “directly related to an important exposure to potentially toxic chemical substances.”

So what’s the solution to these dangerous pesticides? Organic flower production. Companies need to start having environmentally responsible practices.

“Not Something You Can Stop”

Today, the report that I talked about in my last blog was released. The depressing thing? The report says that no matter how much civilization slows or reduces its greenhouse gas emissions, global warming and sea level rise will continue on for centuries.

 This report was called a “very impressive document that goes several steps beyond previous research.” Another find: Scientists are 90% certain that global warming is caused by man. (especially burning of fossil fuels) So to anybody that says global warming is a “natural cycle” and shouldn’t be considered a big deal: This piece of information makes it pretty much impossible to say natural forces are to blame.

 Kevin Trenberth, director of climate analysis for the National Center for Atmospheric Research said:

“This is just not something you can stop. We’re just going to have to live with it. We’re creating a different planet. If you were to come up back in 100 years time, we’ll have a different climate.”

“We’re going to have to live with it” is a phrase that is going to be important in coming years. Adaptation was a word we had to discuss in our chapter homework- it is necessary to adjust to the new conditions. Adaptation is most critical in poor regions because they have the least access to natural resources and don’t have the means to protect themselves from any problems due to changes in climate.

But we shouldn’t give up completely.  Kevin Trenberth said that scientists worry that leaders will take the message in the wrong way. The scientists urged leaders to reduce emissions and also adapt to a warmer world with wilder weather. 

It should be interesting to see if this report will have any effect on Bush’s policy concerning greenhouse gas emissions.
