Idea #1 Genetically modify a crop, such as a tree or invasive species. Select for rapid growth and high respiration rate. Have the plant take carbon from the air and put it back into the ground. Thus reducing the overall greenhouse effect. problems... if the plant is burnt or dies, the carbon will just go back into the air. We have to take the carbon, put it into the ground...and keep it in the ground.
idea #2....Genetically modify a crop so that its root system takes up more than the macro and micro elements it needs. Have it take up another metal or chemical. The plant could take up the metal/chemical up, we can harvest the plant, and that would remove the metal/chemical from that environment. Such a thing has been done with gold...plant takes up gold dust, people burn the plant and collect the gold dust. We can do such a thing for mercury or oil. Both would benefit people. However, i dont know how happy the plants are gonna be, to take up mercury.
idea #3....Modify crops to produce its own, pesticides. Pesticides cost farmers a lot of money. If we can engineer a crop to produce its own pesticide, the farmer wouldnt have to spray, waste money, pollute the environment, kill other microbes, etc. Tabacco produces a alkaloid that acts as a pesticide.
idea #4...look at idea #3 but with respect to fertilizer. nitrogen fixing roots, lets make them work.
Hey guys, i personally like Idea 2 but it looks like i'm out voted with everyone... I think it would be the easiest to find scientific information and since we are in NJ Hg levels are high and could easily be put into a great idea. I think a vote would be best also include a reason so we have motives to sway other such as myself

Hey Everyone,
It's Mena. I did a quick google search for links that might help out for the gm crops presentation. Here's a few links I found. Thanks.

Thank you for the links. I have looked over them.
Hello group. Here are my ideas.
Idea #1 Genetically modify a crop, such as a tree or invasive species. Select for rapid growth and high respiration rate. Have the plant take carbon from the air and put it back into the ground. Thus reducing the overall greenhouse effect. problems... if the plant is burnt or dies, the carbon will just go back into the air. We have to take the carbon, put it into the ground...and keep it in the ground.
idea #2....Genetically modify a crop so that its root system takes up more than the macro and micro elements it needs. Have it take up another metal or chemical. The plant could take up the metal/chemical up, we can harvest the plant, and that would remove the metal/chemical from that environment. Such a thing has been done with gold...plant takes up gold dust, people burn the plant and collect the gold dust. We can do such a thing for mercury or oil. Both would benefit people. However, i dont know how happy the plants are gonna be, to take up mercury.
idea #3....Modify crops to produce its own, pesticides. Pesticides cost farmers a lot of money. If we can engineer a crop to produce its own pesticide, the farmer wouldnt have to spray, waste money, pollute the environment, kill other microbes, etc. Tabacco produces a alkaloid that acts as a pesticide.

Yau,
I like ideas #1 or #3
Hey Everyone.
Thanks for the great ideas. I also agree that idea # 3 and #1 are both really good. I'm leaning towards 3 though. Should we take a vote??
-Selina
I like the ideas guys and I agree with Selena with idea 3 because i'm sure we can find a lot of info about it. So when does everyone want to meet?
