There are only 10 genetically modified crops available today. They are alfalfa, apples, canola, corn (field and sweet), cotton, papaya, potatoes, soybeans, squash and sugar beets.
These crops have been genetically modified to express a positive characteristic that makes the crop easier to manage. An example of these would be improved insect resistance.
Many of these crops are then used as processed ingredients, like sugar or cornstarch. The sugar or cornstarch might then be included in food products at your local grocery store. The only way to eat a GMO directly would be if your store includes varieties of papaya, potatoes, squash, sweet corn or apples in their produce aisle.
The list below identifies the genetic traits expressed and uses of the 10 GMO crops approved in the U.S.
Although most of these GMO crops are edited for herbicide tolerance and/or insect resistance, this does not mean that the plant cells actually make herbicides or release chemicals.
Many of these crops produce a protein that is indigestible to insects. When an insect feasts on the plant, it cannot digest the protein and it dies. Humans CAN digest this protein, so the genetic mutation has zero impact to humans.
Photography is a big part of my life…I don’t know everything but I know some of the key points that I feel are necessary in taking a good photograph. And for Photographer Appreciation Month, I’d love to share a few pointers that can make you a better photographer. Check back every Tuesday this month to learn something new!
Are you wondering how to take a better picture? Well this week’s topic is a simple one that will help improve your photos tremendously.
Find clean backgrounds!
Have you ever noticed a picture of a person with a telephone pole or a tree sticking out of the back of their head? Doesn’t look right does it? If you want to use a tree in the background of your picture just make sure that you place it correctly.
This simple step of having a clean background will take the most average picture and make it an awesome shot. You want to be able to see the bigger picture past what your subject is.
You might be wondering what a clean background is exactly? They are solid colors, generally without distracting power lines or anything that will draw the viewers’ eye away from what you’re shooting. You may have to place your camera at higher or lower level to achieve a clean photo background. Sometimes I stand on chairs or even lay on my belly to get a good shot, (you might look silly but at least you get a nice photo!) By getting at a lower level, you’ll make the background the sky which is more often than not clean. By raising the camera up, you’ll get clean backgrounds such as the ground.
When taking a picture, think of it as in terms of layers. You’ll have your foreground which is closest to the bottom, the middle area is the subject, background is behind the subject, and infinity is what is behind the background.
Photography is a lot of trial and error, so don’t get discouraged! A lot of times you have to play with your layers and see what works and what doesn’t. Always keep your eyes open for a better position to give you a cleaner photo. Sometimes you do want a busy photo, but always look for those clean backgrounds and it will make your photos much more appealing.
CHALLENGE FOR THE WEEK: Give this tip a try. Don’t be afraid to experiment with different angles in search of the clean background.
