The jury is still out on this one. Also bear in mind that there are many types of genetic modification, and some could be safer than others.
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
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.
Farmers have widely addopted GM technology. Between 1996 and 2011, the total surface area of land cultivated with GM crops had increased by a factor of 94, from 17,000 sq km to 1,600,000 sq km. 10% of the GM crop lands were planted with GM crops in 2010. There is a broad scientific consensus that food on the market derived from GM crops poses no important risk to human health than conventional food.
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.
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.
