Answer to Question 1

The first practice is to control the runoff from rainwater. Diversion ditches are cut into areas around livestock facilities to prevent runoff containing waste materials from getting into streams. Drainage ditches divert the runoff into holding areas where risk from runoff is at a minimum. The second practice is to use a lagoon as a holding tank for manure. Here, the material is decomposed through the use of anaerobic bacteria.

Answer to Question 2

A chemical's half-life is the amount of time it takes for half of the amount of the chemical to be eliminated through natural processes.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
