Biotechnology. Genetic Engineering. Recombinant DNA Technology. These phrases all mean the same thing: Genetic Modification. And GM foods are more common than you think. What it means to be GM is that the genetic makeup of the food was directly altered through genetic engineering. More specifically, the rDNA of the food is altered. When you walk through a grocery, you can try to buy something that is not GM, but it may be a little hard. GM does not flat out have a warning that says "CAUTION: THIS FOOD IS GENETICALLY MODIFIED". You have to know what to look for and read the ingredients. Here is an example of what you might see:











If your food product contains any of the following, then make sure to double check whether the ingredients label includes a note that says if it was genetically modified.

• Corn
• Canoloa (edible oil mainly used for cooking)
  
• Flax (a plant used for clothing, seeds and such)
• Soybeans
• Squash
• Potatoes
• Tomatoes
  

So I put myself to the test. When my roommate and I went grocery shopping at Publix, I bought the food I normally would, except this time I wanted to buy everything free of genetic modification. My conclusion? It was pretty hard. I had to buy a specific type of milk made by Silk. The chips I had to buy . Cheese wasn't really a problem, but anything with soybeans, which is a lot of food, I had to surpass. Corn was an option, it was just really hard to find a can of all natural corn.

Endangered Species: a species at risk of extinction because of human activity, changes in climate, changes in predator-prey ratios, etc., esp. when officially designated as such by a governmental agency such as the U.S. Fish and Wildlife Service.

The Florida Keys are home to some of the worlds most beautiful and diverse habitats. Over the years, the Keys have seen many changes, some of them natural, but most of them man-made. Hurricanes have taken their toll throughout the past century, and have slowly withered away the Keys every season. Global warming is responsible for the declining loss of one the worlds last living Coral Reefs, which, in return, loses the capability to provide a home to many diverse underwater species. This alone has put a devastatingly decrease in tourist attraction. Big name corporations are coming in and clearing out the mangroves on newly bought land, which has never seen a human footprint because it was bought out of sanctuary protection, to provide unwanted condominiums, housing, and timeshare resorts. Because of habitat destruction and economic expansion, diverse species are earning an unwanted spot on the Endangered Species list.

Schaus Swallowtail Butterfly

With an average of 200 adult butterflies, this butterfly has been on the Endangered Species list since August 31, 1984. This butterfly lives strictly in subtropical forests, and can be found between Key Biscayne Park to Upper Matecumbe Key of the Florida Keys.

Key Deer

The Key Deer is no indigenous to the Keys, but they have become a well-known and popular trademark. It is believed that they migrated down to the Keys during the Wisconsin Glaciation. They are very human friendly, but it is illegal to come into contact with them. The Key Deer can mostly be found on Big Pine Key and No Name Key, al though they have been spotted as far south as Summerland Key. They look just like their cousins, the White Tale deer, except a bit smaller. Many different theories have developed as to why they are so small. A local favorite is because they eat the leaves of the mangroves, their growth has stunted through evolution because of all of the salt on the leaves.

Lower Keys Marsh Rabbit

The Marsh Rabbit is one of the three Marsh Rabbit species. This rabbit is found anywhere between Big Pine Key and Key West. They are marked with dark brown fur, and a white belly. Commonly, the Marsh Rabbit grows to an average of 350 mm.

Key Largo Woodrat

By its name, you can probably guess where this species resides: Key Largo of the Florida Keys. It feeds mostly on fruit and leaves, and are known for the houses that they build out of sticks. They average about 200mm in length.

Key Largo Cotton Mouse

This mouse is the most common animal in south Florida. Now, they can be found in the Northernmost part of Key Largo. With a red coat of fur, they can grow up to almost 200mm.

Green Sea Turtles

There are seven species of sea turtles, and they can be found in all of the world's oceans, except for the Arctic Ocean. The Green Sea Turtle is known specific to the Pacific and Atlantic Oceans. Because of their beautiful shell, they are a prime target to be illegally caught by poachers. The Florida Keys serve as a main feeding and nesting ground.

American Crocodile

Ranging from 150 to 450 pounds, this massive animal can grow anywhere from 7 to 14 feet long. In the lower keys, it is common, sadly, to see an American Crocodile as roadkill. Eventhough they are a harshly protected species in the Florida keys, they are illegally poached for their skin, teeth, and tails. Alligator meat is highly prized.

Karma isn't the only thing! The Carbon Cycle is the cycle by which carbon is exchanged, transferred, and used among Earth's different spheres. Here is an extremely simplified explanation:

Animals absorb carbon dioxide through the plants that they eat. The carbon is then released through decaying plants and animals into the soil, which is when the decomposers break down the remaining matter all while releasing carbon dioxide back into the atmosphere. Also, plants and trees release carbon dioxide into the atmosphere as a product of respiration, as so do humans. Plants then use the carbon dioxide in the atmosphere to perform photosynthesis. Like I said, extremely simplified.

Unfortunately, carbon dioxide is a Greenhouse gas. "Atmospheric CO2 is currently increased by .5 percent every year, and the increase is expected to continue." Global warming is caused when the amount of energy escaping the atmosphere is less than the amount of energy that is being reached by the earth from the sun.

There are so any ways that you can decrease your carbon footprint. Dont know what your footprint is? Check out this websites:
