SCIENTIFICALLY SPEAKING

Here’s the word on ecological matters for families from TV’s “Newton” scientist, Bill Nye the Science Guy and a mad scientist:

“My biggest concern is the destruction of our natural habitat. Families need to share in their understanding of concern. Adults and young people need to work together, for example, on how to use water more wisely and protect that natural habitat, and make sure they purchase environmentally safe products.”

-- David Heil, host of “Newton’s Apple,” Saturdays at 9:30 a.m. on KCET and Wednesdays at 4:30 p.m. on KBPS.

“The most crucial problem today is air pollution from human transportation. Drive cars less. A great alternative is riding a bike. In the future, I’d like to see our system of roads changed so that many of us could ride comfortable, safe bicycles or human-powered vehicles to school and work.”

-- Bill Nye, host of “Bill Nye, the Science Guy,” Mondays through Thursdays at 7:30 a.m. on KCAL and weekdays at 5 p.m. on KCET and 4 p.m. on KPBS.

“I think the biggest issue has to do with each individual’s personal responsibility as a temporary inhabitant of this planet. We need to take notice of the consequences of our actions. For example, turn off the water when you’re brushing your teeth; don’t let the water run. Parents need to show children what are the appropriate amount of resources to consume.”
