Generate text that refutes this claim: Genetically modified food is a danger to eco-systems.  GM foods also present a danger to the environment. The use of these crops is causing fewer strains to be planted. In a traditional ecosystem based on 100 varieties of rice, a disease wiping out one strain is not too much of a problem. However, if just two strains are planted (as now occurs) and one is wiped out the result is catastrophic. In addition, removing certain varieties of crops causes organisms, which feed on these crops, to be wiped out as well, such as the butterfly population decimated by a recent Monsanto field trial. [1] This supports the concerns that GM plants or transgenes can escape into the environment and that the impacts of broad-spectrum herbicides used with the herbicide tolerant GM crops on the countryside ecosystems have consequences. One of the impacts was that the Bacillus Thuringiensis toxin was produced by Bt crops (GMOs) on no-target species (butterflies), which lead to them dying. [2]  Another concern is also that pollen produced from GM crops can be blown into neighboring fields where it fertilizes unmodified crops. This process (cross-pollination) pollutes the natural gene pool. [3] This in turn makes labeling impossible which reduces consumer choice. This can be prevented with the terminator gene. However, use of this is immoral for reasons outlined below. Furthermore, not all companies have access to the terminator technology.

science general house would ban development genetically modified organisms
The fears about GM food have been nothing more than a media spin. The media have created a story about nothing due to headlines such as 'Frankenfood'. Simply because people are scared they assert that there are not enough testing of the benefits of GM foods.  The proposition is mainly falling into a media trap because at the moment all reasonable precautions are being taken for ensured safety. There is no reason why many different strains of GM crops cannot be produced and planted - where this is not happening at present, it should be.  However, the need for many different strains is not an argument against some or all of those being GM. Adding or removing genes from natural varieties does not make the rest of their DNA identical. Furthermore, there is no concrete scientific evidence of what harm is done by the spreading of GM pollen. [1]  All these effects are considered when a genetically modified crop is to be approved for agricultural use, if a product would cause any of the above mentioned effects, it would not be approved.
