Ever since the devil facial tumor disease (DFTD) emerged in the mid-1990’s‚ the Tasmanian devils’ population has been on a rapid decline. As these devils are a keystone species of their ecosystem‚ their decline has allowed non-native predators such as cats and black rats to flourish and decrease the number of native prey. This effect is an example of the top-down keystone predator hypothesis. Due to the downfall of the devils‚ Australia’s once most intact faunal communities has diverted into an invasive

Bees are vanishing and cell phones are everywhere…there definitely could be a link. The Institute of Science in Society delivered a press release in April 2007 saying “one likely culprit of [CCD] is a new class of systemic pesticides‚ which are not only sprayed on crops‚ but also used universally to dress seeds in conventional agriculture‚ and can confuse and disorientate bees at very low concentrations” although “another candidate is a radiation from mobile phone base stations that has become nearly

The collapse of the honeybee population is due to different factors such as the acquired Immune Deficiency Syndrome or cancer‚ and unknown micro-organism affecting the bees. The two main reasons why bees are dying is because of human using harsh chemicals along with other environmental changes. These chemicals are weakening their immune system. Another reason is because of parasites. The parasites first take over the bee’s body. When the bees have their babies‚ the parasite goes into the honeycomb

$9 billion of agriculture is pollinated by bees annually (Karimi). Bees pollinate many plants around the world‚ some of these plants grow fruit‚ nuts‚ and vegetables. The pollination process happens when bees transfer pollen from one plant to another so that the plants can make seeds and reproduce. Bee populations are rapidly declining. There are threats against the bee colonies which are causing a decrease in the population‚ including : pesticides‚ habit loss‚ wildfires‚ and monoculture. Some

The Decline of The Bee The bee is a vital part of human existence. They pollinate‚ giving life to plants‚ animals‚ and in turn‚ man. If they were to die out‚ the human race would follow suit in a mere matter of years. 65% of all flowering plants require bees for pollination‚ and the percentage being higher for the major crop plants‚ like corn and wheat. These crops account for $47.1 billion every year. Honey bees are responsible for one-third of the food we eat‚ meaning no bees equals no food.

Many species of bees have recently been put on the endangered species list. They are vital to our food supply and help our crops grow. They help produce food‚ fiber‚ and shelter for us. Waves from cell phone towers or the rising heat could be the reason for the species decline in number. We can help to protects the bees by raising hives on our own‚ and by trying not to use harsh pesticides. Bees are what pollinate our crops. Without them the flowers could not be pollinated and would die. Without

Kayla Luft ENR 4000 October 5‚ 2017 Assignment #2 In assignment one I wrote about how pollinating bee populations were declining around the world and the solutions that can prevent this from happening. Addressing this issue can be very difficult. Not only are humans causing this problem but the bee population has a disease that is destroying the colonies. Currently there really isn’t a policy in place to regulate the problem but there are informal efforts that are being put into place by the

Like any 90s kid‚ I played Sonic the Hedgehog religiously. He was uncannily fast‚ curled into a cool ball and tried his best to survive all of the obstacles in the game.
