Genetically Engineered Crops: A Study of Major Environmental Implications and U.S. Policy

The adoption of genetically modified crops is becoming evermore common in United States agriculture. However, this relatively new technology carries a negative stigma and perceived risks that have resulted commonly in public disapproval. In the United States, bioengineered crops are highly regulated. The significance of environmental benefits such as decreased chemical impact, increased soil conservation, heightened carbon sequestration, decreased energy demands, and reduced air emissions, are important enough to warrant a revision to U.S. policy. The U.S. policy structure needs to be simplified and made more efficient to better facilitate the speed with which new GE products can, and should, be developed while still providing adequate mitigation of potential environmental risks such as species invasiveness and impacts on non-target species.

Noxious Weed Management: A Review of Herbicide Use at Colorado State Parks

Weed control in recreation areas is a complex public land management issue. Colorado State Parks are managed for both recreation and conservation, which often conflict. Noxious weeds affect both recreation and conservation efforts, and Parks often use herbicides to control these weeds. While herbicides are effective, they can be harmful to the environment and human health. Herbicide use at State Parks was reviewed to determine if chemical control is effective, safe, and efficient. The results revealed that many Parks are not using effective herbicides to treat noxious weeds and that some weed management plans lack pertinent information on chemical control. The results and recommendations provided can be used to improve the success of noxious weed control and create healthier Parks.
