Negative Effects of GM Crops

A lot of people from all over the world may have already heard about some of the negative effects that GM crops pose on the environment. So much so with the probable health risks that GM crops may supposedly create for lack of extensive safety testing. This may already have a negative impact on the growth and development of the GM and biotech sectors in the industry. But it seems that there are more bad news incoming. 

According to some articles found on the GM Watch website, some GM crops may be on the way of generating some more negative backlash especially on the environmental as well as the economic fronts. On the environmental front it seems that GM crops targeted for use in production of biofuels may find itself suffering from some bad publicity in the days to come. This may be brought about by a certain study made that suggests the biofuel emissions may be producing more greenhouse gases than oil or petroleum when being burned.

This really might be a blow to the biofuel sector that gained popularity as a renewable energy source designed to reduce the emission of greenhouse gasses into the atmosphere. It is the greenhouse gasses in the atmosphere that is said to contribute to the global warming problem and the use of biofuels is said to help curb down the problem. This might seem contradictory to the said study which indicated that the said renewable energy source may actually be adding more to the global warming problem.

A recent study went on to measure the emissions brought about by the burning of biofuels that came from rapeseed and maize crops. It seems that the study discovered that rapeseed and maize biofuels produce 70 and 50 percent more greenhouse gasses respectively as compared to fossil fuels.

The biofuels studied emitted higher levels of nitrous oxide which is even more powerful as a greenhouse gas than carbon dioxide emissions. It was discovered that about 3 to 5 percent of the nitrogen from the fertilizer was emitted when the biofuel was burned. The findings showed the importance of further testing before anything should be hailed as a solution to the problem of global warming

Another effect that has been brought about by the GM crops has been on the economic side, although it might yet be difficult to prove. It seems that the surplus of grains from GM crops has dragged down the value of crops. But according to Peter Lungren on his article from "Some Thoughts From the Tractor Cab", when the US made use of GM crops to boost production but failed in separating their GM crops from those of GM free varieties, they lost a foothold on two of their biggest markets, Japan and Europe.

This brought about a surplus of grains with no ready market to sell to. This surplus was then released into the world market or either given as food aid. This action has started an effect of dragging the price of grains down. Although this effect of GM grain surplus seemed to be very difficult to quantify and prove, it may be seen as one of the reasons of the decrease of prices on the world market.
