To channel shakespeare, the question is “To bee or not to bee?” Well if you ask me, we need to bee. The bees are magnificent creatures. An average honey bee can pollinate anything from flowers and trees to nectarines, peaches, and pears to raspberries, cloves, and squash, if the bees die, we will no longer have those crops. In the 1960s and 1970s, Americans began to use pesticides in large quantities to combat issues with weeds and bugs. Farmers used these chemicals to ensure that they had large yields with their crops. However, their initiatives were short sighted. Singer and song writer Joan Baez writes about this issue in her song, "Big Yellow Taxi" when she asks the farmers to "put down their DDT" because she would rather have "the birds and bees." She's fine with having "spots on her apples." Now fifty years later America is facing a crisis. Although the use of pesticides on these plants are meant to prevent insects, fungi, and pests it is killing the bees making them endangered.
First things first, bees were added to the endangered list for the first time in October 2016. When looking for answers scientists found that most insecticides are toxic to bees. Bees have been seen in parking lots and sidewalks dead in mass.

“Many European countries, including France, Germany, Italy and Slovenia, have already banned neonicotinoids in response to the threat, and beekeepers in these countries report that hives are beginning to recover.” (PAN). Many humans are using IPM (integrated pest management) instead of pesticides. For example, plugging enteryways for pests, not over watering plants or trees and allowing natural enemies to do their jobs. Out of 1400 bees, more than half of them are declining and about a quarter are at risk of extinction. Plant more flowers, trees, etc. Limit pesticide use. Relocating bee hives to a place where pesticides are not used and there are plenty of plants will
The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.
It is not unusual for bees to die or colonies to be lost, but the nature and extent reported in the year 2006 was alarming. Statistics gathered in the United States alone show that 50-90% of the bees have been lost so far, due to this scientific phenomenon (Cox-Foster et al., 2007, p. 284). Honeybees play a very major role in the pollination of plants and therefore these huge losses have become a serious concern. There are many reasons that have been floated and acclaimed to be behind CCD and they include pesticides, parasites, electromagnetic radiation, malnutrition, climatic changes, and urban sprawl, among many others.... ...
Honey bees not only make honey, but they also help pollinate crops worth more than $15 billion a year in the U.S. (NRDC). These small animals are extremely important for providing ecosystem services essential for sustaining biodiversity (Sandrock et al., 2014). However, since the mid-1980s, the honey bee populations have been suddenly declining. This decline is referred to as Colony Collapse Disorder (CCD) (Wu et al., 2011). There are numerous factors that result in CCD. One of the major suspected reasons is due to the exposure to residue of Neonicotinoids, found in nectar and pollen of the flowers. Neonicotinoids are insecticides that lead
The frightening truth is our little pollen buddies are losing their numbers by the millions. Bees are essential to the ecosystem, mainly due to the pollination that they provide to many crops ( “ First” ). Bees pollinate during most of their life which is why they are so vital for most crops to produce seeds. They have hairs on their legs which, gather the pollen on the crops and allow for viable seeds. While some plants can pollinate through other natural ways, a study in the United States concluded that “39% of crops were highly dependent on bees for pollination” ( “First” ). Considering the amount of food that we as
To most, the honeybee can be an annoying insect that has a powerful sting. Yet, the honeybee is so much more than just another insect. The honeybee is arguably the most vital component in the development of our food crops. With roughly 90 percent of our food crops dependent on the pollination of our honeybees, our food system, agricultural development, and diet rest on the work and well being of these buzzing insects. Unfortunately, since 2006 there has been a major decline in the population of honeybees, and has gotten progressively worse because of colony collapse disorder. The first reported increase of CCD was documented in November 2006 in Florida. By February 2007, several states began reporting major losses associated with CCD, ranging from 30% to 90%. A little over a half decade later in 2012 the attention paid towards CCD has grown substantially with more research being done as CCD continues to get worse. The main culprit for CCD, as research has suggested, is the use of pesticides on our food crops. With major corporations such as Bayer making millions and millions of dollars in profit each year in the distribution of pesticides, it is no wonder that nothing is being done to stop this practice despite evidence linking the use of pesticides and the drastic deterioration of the health of honeybees. With the continuation of the use of deadly pesticides and the vital role bees play in the pollination and development of our food crops, both the environment and our economy will be effected directly and face the potential for catastrophic results.
The best action the public can take to improve honey bee survival is not to use pesticides indiscriminately. In particular, the public should avoid applying pesticides during mid-day hours, when honey bees are most likely to be out foraging for nectar and pollen on flowering plants. In addition, the public can plant pollinator-friendly plants—plants that are good sources of nectar and pollen such as red clover, foxglove, bee balm, joe-pye weed, and other native plants.
The Apis Mellifera, or honey bee, have survived on this planet for fifty million years. This species of bee is responsible for pollinating flowers, grass, trees and crops around the world. Much of the food we eat is dependent on honey bees for pollination. Our ecosystem depends on the survival of the honey bee. Colonies of honeybees have been disappearing at an alarming rate around the world due to parasites, viral and bacterial diseases, and the introduction of pesticides and herbicides. Over the past six years, on average, 30 percent of all the honey bee colonies in the U.S. died off over the winter of 2012(NPR/TED). If this trend continues to spiral downward, honey bees will disappear from the world. We must understand the importance of the Honey bee and change our environmental practices in order to sustain this vital insect.
All around the world honeybees are vanishing at an alarming rate, according to the documentary Vanishing of the Honeybees. This film features two commercial bee keepers and their fight to preserve their bee numbers. David Hackenburg was the first commercial bee keeper to go public the bee population was decreasing. Approximately two billions bees have vanished and nobody knows the reason why. Honeybees are used all across America to help pollinate monoculture crops like broccoli, watermelon, cherries, and other produce. Without the honeybees the price for fresh and local produce would be too much money. According, to this film commercial bee keeper’s help fifteen billion dollars of food get pollinated by commercial
How about fruits, vegetables, coffee, even shampoo or lotion? Our livestock depend on bee-pollinated plants like grain. Poorly pollinated plants produce fewer fruits and seeds leading to higher prices (New Agriculturist, n.d.). Some crops are entirely dependent on pollinators such as almonds and others are 90 percent dependent like blueberries and cherries (ABF, 2015). Bees give us honey and we use this honey in food, shampoo, and moisturizers (Mercola, 2015). Bees pollinate 70 out of our 100 major crops; that includes apples, cucumbers, pumpkins, and many more. Our bees are dying at the highest rates ever recorded: 42 percent of the United States bee colonies collapsed in 2015 (NRDC, 2015). 50 to 80 percent of the worlds food supply is directly affected by honeybee pollination (Pennsylvania Apiculture Inc., 2011). Reduced crop pollination will make food more expensive and can even make some crops harder to grow successfully (Worland,
Others include birds, butterflies, and the wind; however, honey bees, by far, are the best at pollinating plants. Collecting pollen is their whole life’s purpose, according to Michigan State University’s article, “Native Plants and Ecosystem Services”. Over one hundred forty three million acres of plants in America are sprayed with a bee-killing insecticide that has been banned in Europe by the European Food Safety Authority (Sarich). Promote ecological farming, and ban all bee-harming pesticides.
In the article, “Rusty Patched Bumblebee Added to Endangered Species List,”written on 1-19-17, the associated press and Newsela staff tells us about how the rusty patched bumblebees’ numbers have been dropping at alarming rate over the past 20 years because they have been experiencing diseases spreading and habitat loss. It has not gone unnoticed though. United States Fish and Wildlife Service have just recently put them on the endangered list. The government plans on rebuilding the bees population by having the citizens provide the bees with more habitat and they want to lower the amount of pesticides and insecticides used that harm bees. Although these bees are endangered, there
High declines in adult bee numbers in some colonies have been reported and this decline is known as colony collapse disorder6. These declines are higher than normal and can go unnoticed by bee keepers because the bees do not generally die in the nest, so the decrease is not immediately obvious. The problem addressed in this paper will be the decline of bees and the effects this decline has on the environment. The solutions proposed for this problem are increasing research, managing farming and spreading awareness. It is important to conserve the bee populations before the problem of decreasing pollinator numbers becomes too great to fix.
Protecting crops is something that has kept farmers busy for quite some time now. It was no different for the Swiss chemist, Paul Muller, who created dichlorodiphenyltrichloroethane, or DDT, in 1939. He was looking for a way to protect wool from moths and DDT seemed to fit the bill. It was a non-soluble powder, which did not harm plants, but was very effective at destroying nuisance pests. DDT was even used during WWII to ward of malaria that kept soldiers sick, thus shortening the war.
Also, the spread of suburbs reduces the pasture areas of the bees, forcing them into cities with much less sources of nectar and clean water than there
Over the past decade bee populations have been dropping drastically. A 40% loss of honeybees happened in the U.S. and U.K. lose 45% of its commercial honeybee since 2010. This is a phenomenon known as Colony Collapse Disorder (CCD) in which worker bees from a beehive abruptly disappear in a short time. These data are definitely not meaningless since bees are a crucial part of the reproductive cycle of many foods. The impact bees have on the agriculture and the environment is far more crucial than we may think. Crops rely on bees to assist their reproduction and bring them life. Bees are renowned in facilitating pollination for most plant life, including over 100 different vegetable and fruit crops. Without bees, there would be a huge decrease in pollination, which later result in reduce in plant growth and food supplies. On the other hand, without the pollination progressed with the assistance from bees, the types of flowers According to Dr. Albert Einstein, “If the bee disappears from the surface of the earth, man would have no more than four years to live. No more bees, no more pollination…no more men”. That’s why bees’ extinction affects people more than we ever think, and could even forebode the doom day of human race.
