While there are anecdotal reports of toxicity to Monarch butterfly larva, there is no scientific evidence of any danger to the environment from GM crops.
There are no proven dangers, only rumor and conjecture.
More productive
Because of the opportunity GM crops provide for greater profit with less risk. Also GM crops give much bigger yields (bushels/acre) and thus more profit over crops that are not GMO.
Because some people do not agree with GM crops and it can cause controversal
GM (genetic modification)
They are not.
Gm crops are the genetically modified crops of food so they dont rot before there sell by date. they are enjected with a gene from another plant.
Of course it is!
the main export market for Israel is Europe which does not approve of GM crops so the answer is: no, there are no commercially grown GM crops in Israel. however Israel it self is not against GM.
Corn and Soybeans
GM crops are produced much like other crops, except that many that are grown have been genetically engineered to be resistant to herbicides or to produce an insecticide in the plant itself.
From the anedotal evidence, potential benefits for the environment of genetic engineering are difficult to find. There have been promises of less chemicals in the form of pesticides being needed for GM crops, but that just has not been shown to be true. Also, "unintentional" cross-breeding of GM varieties with non-GMO varieties, including organically grown crops, has been shown to be occurring.
