Well it depends what type of sustainable agricutlure you are looking at. For example, GM crops can potentially: cross-pollinate with related plants, directly affect the organisms, such as insects, that feed on them and change farming practices. Added to this, it’s possible that an organism modified for one purpose could have undesirable characteristics, for example by becoming invasive, toxic, or immune to its natural diseases. So GM crops must be carefully designed, screened and assessed for risks to the environment before being widely used.

To be truly sustainable, the aim should be for minimum impact on all spheres. This is a difficult ideal to achieve. All agriculture, no matter how mindful of the earth and other ecosystems, is going to have some impact.
Sustainable agriculture should decrease some of the detrimental effects of “conventional” agriculture such as algal blooms due to fertiliser runoff, and damage to organisms from pesticide usage.
