Demand for paper has led to some serious effects on the environment. Paper mills also represent significant sources of water and air pollution, releasing multiple greenhouse gases into the environment and discharging toxic bleach byproducts into the water table. The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. Compasses made it possible for explorers to sail far out into oceans and away from land—no matter what the weather was like. This led to more exploration, the discovery of new countries, and trade with other cultures.
