Whether it is a shopping bag, a food bag or a trash bag, they are all made of plastic bags. Grocery store owners are very generous in using plastic bags. They place the fruit in one bag and drop the box of milk in another. Ever wonder why? The positive side of plastic bags Grocery stores, shopping centres, and restaurants are not thrifty in using and giving out plastic bags because they cost no more than a cent each, while a paper bag costs four cents. Plastic bags are produced so cheaply and massively that they are used by 80% of store owners. In addition, they are light and very easy to carry and store. The production of plastic bags has increased greatly over the last 20 years and producers of plastic bags are making large profits. However, the negative side of plastic bags is becoming well-known. More people are now getting worried that the earth is becoming a victim of the plastic bag success story. The negative side of plastic bags While production and consumption of plastic bags is good for business, it is not so for our Mother Earth.

They make the oceans poison sea animals. They give off toxins when burned. They simply pollute the ground, air and water. That is the true cost of plastic bags, and it looks like it is more than a cent. These are very alarming concerns and proper action needs to be taken.

Read the following article and select the best answer. Article: "I drink caffeine to stay awake. It has positive effects on me. I'm healthy, and there's nothing wrong with me," said Sarah Green, a freshman, who consumes many caffeine drinks to stay awake in completing the many tasks in her busy schedule. Caffeine is known to have many positive and negative consequences, and now that there might be an additional positive effect may have been discovered. A study suggests that a skin lotion containing caffeine, which is also found in green tea, may reduce the risk of skin cancer. Two lotion tests were conducted on hairless mice that were exposed to high levels of ultraviolet radiation . As a result, the lotion reduced the number of tumors each mouse developed. Unlike sunscreen , the new lotion is applied after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer. Caffeine obstructs this action and causes the diseased cells to kill themselves. "I know that caffeine has been found in certain drinks and it causes increased activity of the nervous system, and increased blood pressure on blood vessels . I don't know of any positive effects of caffeine," health teacher Montego Estes said. Caffeine, found commonly in tea, coffee and soft drinks, provides people with an increase in energy. Half of all American adults consume more than 300 milligrams of caffeine per day. Caffeine is addictive because it uses the same mechanisms as amphetamines , and cocaine and heroin to excite the brain. "This new cream doesn't sound to me as though it would work," junior David Bobbit said, "Caffeine seems to have more negative effects than positive ones." Skin cancer is the most common of all cancers in the US. About one million cases will be diagnosed in the country this year. There will be more than 88,000 new cases of melanoma , the disease's deadliest form of skin cancer. Question: It can be inferred from this passage that _ . - Sarah Green knows caffeine can protect her from skin cancer - Exposure to ultraviolet rays is always blamed for skin cancer - Caffeine will be used in medicine to treat skin cancer patients soon - In a way, the study on caffeine is good news for many Americans
