Applications to release genetically modified organisms (gmos) into the environment, usually the agricultural environment, are increasing exponentially.
Genetically modified (gm) crops are subject to regulatory approval before entering the market. In the european union (eu), for example, approval of a gm crop for commercial cultivation requires an environmental risk assessment (era) of potential adverse effects on human health and on the environment (and on biodiversity in particular). 1 approval is only granted if the era indicates that the risks of the gm crop are negligible.
One way of thinking generally about the environmental harm that genetically engineered plants might do is to consider that they might become weeds. Here, weeds means all plants in places where humans do not want them.

Applications to release genetically modified organisms (gmos) into the environment, usually the agricultural environment, are increasing exponentially. Studies of biological invasions and of biological control show that the probability that a genetically new organism establishing itself is small; it is also unpredictable and in some cases could have severe ecological effects.

European risk managers currently face substantial difficulty in evaluating the risks of genetically modified (gm) crops for biodiversity. This difficulty is not primarily due to a lack of scientific data (the data are abundant) but rather to a lack of clear criteria for determining what represents environmental harm.

The risks of genetically modified organisms (gmos) are evaluated traditionally by combining hazard identification and exposure estimates to provide decision support for regulatory agencies. We question the utility of the classical risk paradigm and discuss its evolution in gmo risk assessment. First, we consider the problem of uncertainty, by comparing risk assessment for environmental toxins.
The current state of knowledge reveals that gm crops impart damaging impacts on the environment such as modification in crop pervasiveness or invasiveness, the emergence of herbicide and insecticide tolerance, transgene stacking and disturbed biodiversity, but these impacts require a more in-depth view and critical research so as to unveil further facts.
Discussions of the environmental risks and benefits of adopting genetically engineered organisms are highly polarized between pro- and anti-biotechnology groups, but the current state of our knowledge is frequently overlooked in this debate.

Negative effects on the environment include increased use of herbicides and pollution of aquatic ecosystems. These fundamental issues will comprise the focus of this paper. Given the negative impacts and the need for gmos for food production, the only way to cope with this dichotomy is to decrease the environmental impact without eliminating.
The environmental risks and benefits of genetically modified crops have varying degrees of certainty. Regulatory system evaluates a suite of hazards for the crops primarily by minimizing type i error. However, genetically modified crops vary widely in their potential for environmental harm.
Risky business after seven years of gm crop production and no apparent health effects, potential environmental risks—particularly gene flow into other species—have eclipsed food safety as a primary concern. As pollen and seeds move in the environment, they can transmit genetic traits to nearby crops or wild relatives.
The effects of gmos on the environment remain one of the biggest concerns. For example, farmers might fail to limit genetically modified crops to a certain area. Bees take pollen from genetically altered corn, and they might transfer it between fields.
Gmo foods present huge potential risks to the food supply and environment. Studies have shown that pesticide-producing crops contaminate nearby streams, cross-pollination from genetically modified plants contaminates organic crops, and whole species of insects and other important organisms are disappearing due to the toxins produced by gmo foods. If this continues, it will lead to a significantly lower level of biodiversity, putting the whole food system in danger.
