The Pros And Cons Of Cross-Breeding

1185 Words5 Pages

Cross-breeding two different species together has resulted in many new animals over the years, such as mules (a horse and a donkey) and ligers (a lion and a tiger). However, no cross-bred species has created as many problems as the Africanized Honey Bee; a breed between African Honeybees and European bees in an effort to produce more honey. After escaping from a quarantined lab, these bees have become an invasive species in Central and North America, migrating further north each year. Here they have caused problems. This raises the question; should their populations be controlled? Some say that we should attempt to control their spread, whilst others say to leave them to it, as they cause no real harm. Cross-breeding is a phenomena rarely …show more content…

It is always an ethical concern when humans come to harm. As well as this, Africanized Honeybees are outcompeting and breeding with the European Honeybees used to produce honey for beekeepers (Tarpy, 2012). This can be seen as a problem, as European Honeybees are already in sharp decline due to Colony Collapse Disorder. When they are outcompeted, their numbers fall and when they are bred with, the genetic superiority of the Killer Bees ensures that the offspring retain the features of the Africanized Bee (Ojar, 2002). However, there are also many points that suggest leaving the Africanized bees alone, or rather utilizing them to suit our needs. As previously mentioned, the Africanized Honeybee produces even more honey than the European honeybee; being less picky about flowers, travelling further from the hive, foraging for longer each day and in harsher conditions and consuming less of the honey they collect than the European bees (Sears, …show more content…

Their increased production, reliability, immunity to Colony Collapse, genetic dominance, and resistance to environmental change has allowed them to replace the European bees. It has also been observed that, in the areas in which Killer Bees are primarily used for honey production, the bees become more docile (Vance, 2013). This is likely due to the keepers selectively breeding the individuals which are more relaxed, more or less making the aggression problem void. It is believed that these gentler Africanized bees have typically possess more genetic material from their European counterparts rather than the African bees (Smithsonian Museum,

In the novel, the conflict is caused because all the bees in the world die. If that were to happen, not only would a major pollinator disappear from the earth, thus destroying fauna throughout the world, but animals that rely on bees as part of the food chain would also suffer. In Stung, the absence of the bees leads to a pandemic, which scientists then try to solve with a vaccine. However, the vaccine turns children into beasts instead of curing them of the disease that threatens to engulf the entire human race. Finally, at the end of the book, a successful vaccine is discovered, allowing science to mitigate some of the damage it caused—but that does not change or excuse the fact that pesticides and vaccines nearly caused the extinction of humans as well as other

This project was chosen to investigate the decline of the honeybee and the impact on Australian agriculture. The honeybee decline is interconnected with environmental sustainability with key environmental challenges threatening the future of the honeybee and the industry of beekeeping. Some of these factors such as land degradation, limited water availability, loss of plant biodiversity, climate change, pests and pesticides loss of public lands such as National Parks, State forests and reserves, all impact on the sustainability and ecosystems which the honeybee depends and likewise, the ecosystems depend on the honeybee. With the disappearance of land to urbanisation and government restrictions on access to public lands some 70% of Australian

One could look at a bee hive as a single living entity (otherwise known as a Superorganism).They ingest and digest food,regulate water control and achieve locomotion as well as many other things that humans do to stay alive. This is were the similarities stop. Bees are raised for certain jobs that are never changed. Queens lay eggs,Drones mate with queens,and workers well….. They work.

Bees in Decline Honey bees visit around 50-100 different flowers in one collection trip for honey; What would happen if millions of hives are declining in populations? The decline in bees is a serious problem that could cause the beautiful spring colors to turn dark and saturated without colors. This epidemic is worldwide, and could be a serious problem, more than one third of what goes on your plate is made with products that have been pollinated by bees (The Bees in). The bees have been declining in most of Europe because of the rough cold winters they have had the past years dropping their populations by almost 53%, as well as pesticides dropping the populations and killing of the entirety of a single hive ().

Until that feeble kind you know are dominated by the Africanized killer bees, and the Africanized ones are the only ones left! The killer bees can chase someone/thing for over a mile. They are far more aggressive than a regular bee. Just recently in a California town dozens were wounded because of a bee attack.

In “The Human Bumblebee” by Michael Pollan, the author argues that humans are not superior to other living species and often take them for granted. Pollan points out the important role these insects play in the natural world and the ways in which human actions can negatively impact their populations.. Through his writing, Pollan challenges readers to consider their own place in the natural world and the responsibility that we have to respect and protect other species. Pollan was exploring the concept of business and control in gardening through his question. Micheal Pollan states,“Did I choose to plant these potatoes, or the potatoes chose me?”(5).

There is a lot of buzz about the Bee Colony Collapse Disorder which is, according to dictionary.com, a pathological condition which leads to a disappearance of worker bees from the hive resulting in the hive’s failure. The reason I am concerned about this topic is because human survival is tied to bee survival. Bees are responsible for ⅓ of the meals we eat, either by pollinating the fruits and vegetables that humans eat or by pollinating crops that feed animals that we eat, like cows. It is difficult to come up with a solution to this issue because there are many root causes. Bee Colony Collapse Disorder is a bigger problem than most people realize, and if it is not solved, it will have a devastating effect by taking away important food that

Based on a scientific analys , the very accelerated loss of species that we are experiencing could be up to 1,000 to 10,000 losses per year. these losses do not only include wild animals or mammals that are constantly haunted , but also small pollinators such as bees. the bee decline is a an issue that is currently affecting most of North America and many countries in Europe , but the number of bee colonies are increasing in China . But if this issue is not solve as soon as possible , and the decline increases it will eventually become a worldwide issue.

The Agricultural Research Service (ARS), the USDA’s internal research agency is leading several efforts to find the cause of Colony Collapse Disorder, and ways to stop it. The ARS has been striving to enhance honey bee regulation and health as well by improving bee management practices and studying honey bee diseases, vectors, and how to control them. Plus, a number of Federal agencies and state departments of agriculture, private companies, and universities have all started to seek the source and treatment of Colony Collapse Disorder. This is not the first time that bee population has declined drastically. There have been several periods in recent history that bees have been documented to have severe population loss, the 1880’s, 1920’s, and 1960’s.

This again stops the bees from doing their job of pollinating and stops them from getting the food they need to survive. The community can help bees survive by employing a few tactics. One tactic alone will not cure the bee population degradation but it can help boost the bee population. One local and more personal tactic would be to have a “bee garden” that consists of flowering plants that bees like which include apples, oranges, lemons, limes, cucumbers, carrots, and cantaloupes. Another tactic would be do be more environmentally conscious.

“Beekeepers across the United States lost 44 percent of their honey bee colonies during the year spanning from April 2015 to April 2016” (“Nation’s Beekeepers lost 44 percent of bees in 2015-2016”). Many famers today plant their cops in sections farther apart depending on the plant. When the bees go to collect nectar they cannot get as much food without getting tired. This has had an effect on bees because they die faster from having to fly so far. Many beekeepers think that this reason causes bees to fade away.

Bees do not go far, so they pollinate local areas rather than an extended amount of land. Patricia E. Salkin says, “Small-scale beekeeping has proven to be especially popular among people looking to obtain more of their food from local resources.” Not only does it help the people and the wildlife in their surrounding area, it supports producers who raise and sell their crops there. Patricia E. Salkin states, “Urban bees provide important pollination services to community gardens, home vegetable gardens, and fruit trees.” Not only will it help neighbors’ goods and plants, but it will help others’ gardens and plants as well.

Everybody can help out, just by doing one simple thing. Get out and grow bee-friendly plants. You could decorate your yard with them, or even grow them in a pot. It doesn’t matter if you live on a private island or a rabbit hole. One person can not solve this problem, just like how one honeybee can not produce a whole jar of honey.

Imagine entering your local food store and seeing that items most people eat everyday have been discontinued. Items such as coffee, apples, cucumbers and honey are no longer available to consumers. This may not be possible in our generation, but one day it could very well happen. My name is Matt Shaw from the Millsap FFA, and I am here today to talk to you about a major issue that is facing agriculture, the honeybee population.

Bees are major factor in our environment. But recent studies show that we are to blame for the decline in the Bee populations. The main reasons are industrial agriculture (pesticides), mites and climate change. And we should care about them because they provide us with honey and beeswax, and provide a major ecosystem service in the form of pollination. Bees pollinate a lot of crops like apple, citrus, strawberry, blueberry, tomato, melon, oilseed rape, carrot, etc.
