Consider such things as dangers to humans, the depletion of resources, air and water pollution, discovery before inventions, impact on wildlife and humans (health and safety), long-term and short-term effects, waste disposal, and aesthetic considerations (how nanotechnology changes the landscape). Look also at the positive effects (savings of raw materials or fossil fuels, low environmental impact, enhancement to the environment). For example, some thought the Alaskan Pipeline would impact the caribou population and its ability to migrate; the scientists discovered that the population actually increased and was healthier because they had “shade” from the above-the-ground pipe, fewer biting flies, and less physically stressed females. Other negative examples: The spotted owl and deforestation in Washington State; the snail darter and the dam, endangered species and loss of habitats, extinction, over-mining, overproduction, pollution of ground water, landfills, toxic wastes, stripping the soil of nutrients, over fishing, over hunting, and over harvesting.
