The protection comes from chemicals known as isothiocyanates found in these vegetables. Researchers found that men with no detectable levels of isothiocyanates had a 36 percent greater chance of developing lung cancer than those who did have the chemical in their bodies. These results held true even after researchers took into account subjects who smoked. Recycling is a way of life for some. Others don't think it's worth the extra effort.
Recycling saves energy - lots of it.
For instance, making paper from recycled paper products uses 64 percent less energy than making it from wood pulp. Containers made from recycled plastic use 60 percent less energy than making the same product from new materials. The process occurs too slowly to affect sea levels on a human time scale, but over time it would significantly affect coastal ecosystems.
