Cancer in rats reignites GM food debate A new study has reignited the debate over the long-term health effects of eating genetically modified food. Published in the journal of Food and Chemical Toxicology‚ results of the study show that rats fed a GM diet over their lifespan suffered mammary tumours and severe liver and kidney damage. Advocates of the study say Australia’s regulatory bodies should act on the findings‚ but some scientists have criticised the study‚ saying it is seriously

10/26/12 THE FUTURE OF FOOD You might think you know everything about the foods that you eat or place on the plates for your family‚ but you have no idea. The Future of Food is a documentary that reveals appalling or should I say shocking information regarding our crops that are grown in the U.S. today and how big corporations are taking over and altering the foods that we eat through science‚ all because of corporate greed. What’s even more terrifying is that majority of consumers have no

Genetically Modified Food Genetically modified foods are food derived from ‘genetically modified organisms’(GMOs). Genetically modified organism had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non- specific but stable change. Other techniques by which humans modify food organism include selective breeding: plant breeding

“The High Cost of High-Tech Foods” 1. What are the ethical issues in this case?? The ethical issues in this case revolve around the consumption of genetically modified (GM) foods. We have the supporters of GM food arguing that judging the actual risk should not occur until extensive scientific research has been conducted. Until then‚ they believe that these crops can effectively aid in feeding the world’s needy by providing higher per acre yields while having a reduced need for pesticides

The research question which will be attempted to be answered is whether the biocontrol agent‚ Thaumastocoris peregrinus (bronze bug) attack other plants except for the eucalyptus species. Hypothesis: It is expected that T. peregrinus does attack other nearby plant species and does not only feed on eucalyptus plants. Aim: To determine whether T. peregrinus feeds on other species of plants other than the eucalyptus species. Introduction: The T. peregrinus‚ also known as the bronze bug is known as

The two advantages of dehorning cattle to farmer is it makes animals easier to handle and it increases farmer’s profit. The first advantage of dehorning cattle is it makes the cattle easier to handle. This is because dehorned cattle exhibit fewer aggressive behaviours. Judge (2015) writes that presence of horn on cattle make them more dangerous as the animal used their horn for both offensive and defensive purpose. In addition‚ dehorned cattle present a lower injury risk for farmer. Judge (2015)

Ninety percent of GMO crops are designed to be Roundup ready. What that means is farmers can spray Roundup weed killer DIRECTLY onto crops that will be turned into the food that you and your family eat. That’s right. These crops that are turned into food that finds its way to your dinner table‚ have been genetically modified so that they can be sprayed directly with Roundup poison and survive. The poison is absorbed internally into every cell of the plant. It is then harvested‚ processed into food

The book‚ Silent Spring‚ by Rachel Carson is regarded as the most significant environmental novel as it was the start of the environmental movement. This book highlights the human poisoning of the biosphere through chemicals aimed at pests and disease control‚ particularly dichlorodiphenyltrichloroethane (DDT). DDT pesticides were particularly harmful because as they entered the biosphere‚ they not only killed the bugs but also entered the food chain. DDT accumulated in the fatty tissues of animals

Pesticides are substances used for destroying organisms that are harmful to crops. There are many different forms of pesticides‚ but whichever form it is they harm‚ and kill Bumble bees. Bumble Bees pollinate about 15 percent of our food‚ and are valued at 3 billion dollars (Adam Federman). Bees are extremely important pollinators that we need‚ but yet we are killing them off indirectly with the pesticides we use on crops. A pesticide called neonicotinoids is one example of how pesticides are
