Recommended: Human impacts on ecosystems
Humans are going to be the end of the world. Ever since humans turned to machines for help, it's caused disastrous results on the planet. We pollute the atmosphere, kill off countless species without a second thought, and continue to destroy the planet and everything on it. Due to these actions, many plant and animal species, including humans, could be driven to extremely small numbers and quite possibly extinction, due to the 6th mass extinction, caused mainly by human influence. It may be true that extinction can help the environment, though by lowering population sizes so overcrowding doesn’t ensue, or to give to the new, better species. However, extinction rates have skyrocketed lately as scientists have noticed, with species being lost at 1,000-10,000 times greater than normal. This means that thirty to fifty percent of all species could be extinct by the middle of the 21st century(Center for Biological Diversity) according to research. This increase in extinction is mainly caused by humans. Acts …show more content…
They pollinate plants, which animals eat, in which humans eat. Without them, life would have a very hard time surviving, as 75% of the world’s crops depends on pollination(The bee crisis: a global matter of life or death). But due to mites, poor nutrition, and pesticides, the population of bees suffers from CCD, or colony collapse disorder(New survey shows bees are in trouble. What's being done to save them?). Due to these factors, the honeybee population has declined by almost 50% between 2015-16(Nation’s Beekeepers Lost 44 Percent of Bees in 2015-16). Humans are doing little to none to help reduce this decline in the bee population, but instead worsening the problem. If this problem isn’t soon resolved, then the bees will die, decreasing the amount of plants eaten by animals, decreasing the animal population, which are eaten then by humans, driving the human population to extinction, caused by
What do you think when you think of bees? I think of honey, pollination, and soon, new life. According to Walt D. Osborne, “Bees are vital for the pollination of more than 90 fruit and vegetable crops worldwide, including almonds, peaches, soybeans, apples, pears, cherries, raspberries, blackberries, cranberries, watermelons, cantaloupes, cucumbers, and strawberries,” (Osborne 9-11) but each year a large percent of hives have vanished due to many different factors such as stress. Most people would declare that the average honey bee is insufficiently important to the world because bees are pests to home owners everywhere, but bees are extremely important to earths’ survival than any other pollinator in the world; they help pollinate most of the world’s agriculture; yet in the recent years bee populations have plummeted rapidly. I am writing this paper to create awareness that the agricultural society ought to stop or lessen the spraying of pesticides/ insecticides on crops, unnatural diets and overcrowding in the hives.
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.... ...
On a day to day basis, most people take for granted the lives we get to live, and put too much value on the extra things such as materialistic items. Also, the majority of humans are too invested in their personal lives or with themselves that they do not look at the big picture of how what we are doing now will effect us later. As humans, the routines in our lives can bring us harm, and within time a we may become the sixth extinction. In “The Sixth Extinction” by Elizabeth Kolbert, she gives many examples of animals that are or may become extinct. Along with ways humans contribute to the effort of putting them in danger or having them become extinct. In the end having a summary of how this all comes together and impacts us humans in more
People from all over the world, from every walk of life, regardless of color, age, gender or religious beliefs all have one thing in common, that is to consume food in order to survive. Many places around the world have food scares yet America has access to a lavish selection of crops to choose from. The most nutritious part of any human’s diet is a result of insect pollination. In such manner, pesticide use is causing honey bee colony collapse disorder putting their existence in grave danger and posing major food source shortages.
Think for a moment of a world without bees; a world without our buzzing friend. They might look like they barely do much to help our ecosystem. However, bees are a vital part of our agriculture and this makes it vital that we keep them around. The bee population decline in recent years is troubling for both us and our little friends. As their friends, we must do all we can in order to ensure their survival which in turn will ensure our own.
Just how important are honey bees to the ecosystem? Typically, according to the U.S. Department of Agriculture, Honeybees pollinate eighty percent of our crops, or about a third of our diet. Honeybees cross-pollinate different plant species, by carrying pollen, which it uses to spread throughout an area of flowers. On a larger scale, one bee colony is able to pollinate 300 million flowers each day (Greenpeace). Grains, like rice and wheat, are primarily populated by wind, however, the healthiest foods, such as fruit, vegetables and nuts are pollinated by bees. In order for humankind to grow the honeybees must be able to live.
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
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 world's 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, 2015).
The worldwide eradication of honey bees may not be too far away. The reasons the honey bees are dying are linked to a number of things. The most common causes are linked to industrial agriculture, parasites/pathogens, and climate change, according to the article entitled “The Bees in Decline” on GreenPeace’s website, SOS-bees.org. However, bee-killing pesticides pose the highest risk to the pollinators (the Bees). Honey bees are not the only form of pollinators.
The lives of humans and honeybees have been intertwined for millennia. For at least 8,000 years, humans have sought honey for applications in disciplines ranging from medicine to the culinary arts. But while humans love honey, honeybees provide a much more valuable service: pollination. As the world’s most prolific pollinator, honeybees are essential to the reproduction of many plant species, which in turn benefits other animals and plants. In fact, humans heavily rely on honeybees to pollinate our own food source, a service that is worth billions of dollars a year. Unfortunately, the honeybee population is in a severe and prolonged decline, often in the form of colony collapse disorder, in which entire colonies are seemingly abandoned by adult bees overnight. Honeybees are an indispensable component of modern agriculture, and a failure to discern and address the many causes of honeybee population decline – both manmade and natural – could have disastrous consequences for the environment and human society.
Pollinators are very important to the environment because many plant species rely on reproduction to be carried out by pollination1. Bees are dependent on plants for pollen and nectar and in return, are the most common pollinator of plant species and around 90 percent of plants require pollination by an animal7. Bees are used in farming, both for pollinating crops and for producing honey, and the estimated value of bees to the United Kingdom is £400 million per year9. Plants are the primary producers in many food webs and, as so many are dependent on pollination in order to reproduce, a decline in pollinators would have a detrimental effect on whole ecosystems. Therefore, the declining numbers of pollinators, particularly bees, are a cause of concern because of the environmental knock-on effects.
Humans are destructive. Not a lot of us think about how what we do affects the world around us. We almost act like we are the only ones on this planet. We go around polluting and destroying our world with no regard for our actions. The things that live out in the wild are paying the price for it. Every day that passes there is another animal or plant that is placed on an endangered list. This is happening at an alarming rate. Because of man’s desire to expand and conquer their surroundings, there are animals and plants that are on the brink of extinction that will not be around for our kids and future generations to enjoy if something is not done about it now. This problem has been going on for hundreds of years. There are animals and plants that can only been seen in paintings or early photography. It is because of our early ancestors that we have this problem today and we have to do more to prevent more animals and plants from disappearing forever.
...a faster rate than ever. Data from graphs evidently prove this theory. From the graph the greatest leap of extinction is seen 1920s till now. This trend line is drastically increasing (figure 4). Experts say that approximately half of the world’s current species will be entirely gone by the end of the century, hence proving that we are in the middle of an anthropogenic mass extinction.
Currently “we are living through the sixth mass extinction, [and] this one is introduced by human activity” (Benton, 2011). As of today scientists have recorded five mass extinctions. While there is no perfect definition for a mass extinction, due to how each differ in so many aspects, a mass extinction is most simply defined as when the number of species on earth drops drastically due to a certain event or cause. The five mass extinctions; the late Ordovician, the late Devonian, the late Permian, the late triassic, and the late Cretaceous all had varying natural causes such as meteorites and extreme weather changes like the Ice age, however “today scientists say we are facing mass extinctions from another cause, humans. (Humans can be primary, 2007)”.
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.
