When you’re trying to teach your kid about the importance of saving the earth and protecting the environment for future generations, it can be worthwhile making the subject a little more interesting to them by relating the topic to cars, and in particular, hybrid cars.
There’s a short answer to your child’s predictable question of whether hybrid cars are better for the environment – which is simply a resounding “yes”. But as with most things in life, it’s a little more complicated than that in practice. Hybrid cars certainly reduce emissions of harmful substances to a significant degree – which is what we’re really interested in. When compared to a conventional petrol engine car, hybrid cars reduce harmful emissions by around 70% to 90% of carbon monoxide, hydrocarbons and Nitrogen Oxide (NOx). Also, most electric petrol hybrid cars reduce lifecycle greenhouse gas emissions by at least 25% compared to an equivalent petrol only car.
So what complications are there? Well the manufacturing process to produce hybrid cars is a little more complex and environmentally damaging substances such as NOx are increased. Also, purchase prices are still generally higher for hybrids than for
conventional cars. Although this may change over time, it remains an
undisputable fact at present. “What’s this got to do with the environment?” I hear you ask. Well, nothing directly, but if a consumer has paid significantly more for
his/her vehicle, then there is the possibility that the same individual will seek cost savings in other consumption to make up the difference – choices which may not be as environmentally friendly perhaps.
This is something of a moot point, however, and hybrid cars are undoubtedly the superior choice for today’s green thinking motorist. There are, of course, even more environmentally-friendly options available like not owning a car at all, or choosing a purely electrically powered vehicle, but practicalities dictate that for most of us – the hybrid is the most realistic current “green”option.
No doubt adults, children and even babies – all of us have the ability to grow and adapt to daily challenges in life. The fact is the twenty-first century promises to be “the century of brain.” The above technologies and other advances will enable us to shed light on the problems of the human mind. The time has come for us to apply the results of brain science research to improving education as a social technology. There is “art of changing the brain” that comes down to some things that we have always known. Practice and meaning are the most important parts of this art, but of course the student will not practice in a meaningful way unless she cares. Ultimately it is the learner that is in control. The teacher can arrange the conditions and the challenges in ways that engage the learner, but still we must have faith in learning itself.
