Q)What economic and ecological roles do honeybees play? A)They pollinate many of our fruit products. They also make it so we can grow these products and sell them without the great cost of hand pollination. 6Q)Describe the poaching of wild species and give three examples of species that are threatened by this illigal activity. A)Some protected species are illegaly killes for their valuable parts or are sold to live collectors.
According to California Invasive Plant Council for Spring 2009 says that weeds alone cost California $82 million a year and that also suggest that invasive species has cost the United States $138 billion. That is a lot of money and a lot of product that was lost because of the contamination of the crops and grapes. The glassy-winged sharpshooter (GWSS) feeds off the stems and happen to be at least 100,000 -150,000 insects per tree and they affect over 130 different plants. When feeding off the stems, the stem carry so much fluid that when the GWSS feed they consume large amounts to have energy and to grow. After filtering the essential nutrient from the stem it releases a small droplet that is later visible when it is
Effects of introduction of Cane Toads species in the Australian Ecosystem Name Name of institution 12th May 2015 Introduction Introduced species refers to the plant or an animal that is not native to a particular place. These species are known to have the tendency of spreading quickly thus damaging the environment, human health as well as the human economy. The introduction of these species can either be accidental or deliberate. The deliberate cause of the introduction of these species can be either to control other species or for sporting purposes. The introduced species that cause negative effects to the local environment are referred to as the invasive species.
Colony Collapse Disorder The colony collapse disorder of honeybees has become a very problematic issue. The Natural Resources Defense Council states that nearly that nearly one-third of all honeybee colonies in the country have vanished, putting many fruits and vegetables at risk. A controversial type of pesticide called neonicotinoids has become a prime suspect in this phenomenon, as it affects bees’ sense of direction and making it hard for them to find home. In order to prevent this disaster from continuously occurring, neonicotinoids should be banned or used more sparingly and replaced with an alternative type of pesticide. Author Brandon Keim, author of article “Controversial Pesticide Linked to Bee Collapse” states neonicotinoids began to be used in the mid-1990s as less-toxic alternatives to human-damaging pesticides.
It has been recorded at a number of sites within the park. The fungus has the potential to impact of the vegetation, especially along the heathy ridge tops where grass trees are dying. It also affects a lot of the native vegetation and causes the death of a lot of other species. The disease spreads naturally but also through infected soil when transportation travel over it. Quarantine and vehicle hygiene to limit the spread can only be achieved my
This strong species is a voracious predator of insects and other small prey. Cane toads possess the capability of poisoning their predators. The introduction of this species to Australia was directed as a form of biological control. Cane toads were supposedly a ‘solution’ to the pest beetles in the sugar cane industry in 1935, before the use of agricultural chemicals became widespread. Although this ‘solution’ failed in its attempts to control the issue, cane toads were very successful at invading the ecosystems of Australia’s north.
Bush Honeysuckles Bush Honeysuckles are inavasive species plants that grow quickly and agressivly diplacing other Plants. Bush Honeysuckles are harmful to plants, mammals, and wildlife. Of the roughly 2,300 inavasive plant species in Indiana, 25% are non native and are responsible for degrading and destroying thousands of acres of our natural plant communities of Indiana. Bush Honeysuckles where introduced to Northern America in late 1800s and 1900s. They are now reported to be found in 81 counties in Indiana.
A counter argument to one of the disadvantages of genetically modified food Some antibiotics can be transferred to humans and make it harder for us to fight infections, genetically modifying foods could potentially put farmers out of work, and some important insects could be at risk because of the insecticides in foods. 6. Picture of the
No matter how many flyers would be sent out to residences, nor how many commercials announced that pesticide would be sprayed on a particular day there are still citizens that would have been uninformed to what was taking place. The poor citizens that do have television and the uneducated citizens that would not understand what they were reading and the harmful effects that the pesticide would have on them would be the ones typically to be outdoors when the spraying is taking place. The agricultural workers in the fields would be sprayed or would handle fruit or vegetables with the residue from the pesticide and get very ill. Killing the mosquitoes is a short term fix, when in all actuality the city needs to take the money donated and educate the citizens and tourist on how to avoid contracting the West Niles Virus. Educating people how to take care of themselves is a long term solution that will not cause irreparable damage to the
David Kim AP Lang A, Welch Period 5 October 3, 2014 “California Cracks Down On Farmers Market Cheaters” I. “California Cracks Down on Farmer’s Market Cheaters” written by Dans Charles was published on October 2, 2014. This article describes the fact that there are people who are currently deceiving consumers of the Farmer’s Market by claiming their produce has been grown locally, while in reality, they are selling wholesale goods from different markets labeling them as locally grown produce. II. The author focuses an indicative mood towards how there are farmers that currently label some market-goods as locally farmed produce.
