Water of the 21st Century

Life on earth depends on water,and there is no substitute for it. The current assumption is that our basic needs for water-whether for drinking, agriculture, industry or the raising of fish--will always have to be met. Given that premise, there are two basic routes we can go. more equitable access to water or more drastic engineering solutions. Looking at the engineering solution first, a lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal change of the river--the pulse of the water. And the fact is that if you build a dam, you generally wreck the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the next century, governments will have no excuse for their blissful ignorance. The engineers ability to control water flows has created new kinds of uNPRedictability too. 'Dams in Africa have meant fewer fish, less grazing and less floodplain agriculture--none of which were anticipated. And their average economic life is assumed to be thirty years. Dams don't exist for ever, but what will replace them is not clear. The key issue in any discussion of water is money. To talk about a water crisis hides intractable problems such as poverty. Consider the problems of water supply in Mexico City or Delhi. If you' re rich, you drink mineral water and may even have a swimming-pool--yet millions in such cities can't get safe drinking water. People talk about the coming water crisis. I believe we have one now. It is a water crisis for the poor.

Speaking Effective American English

On job interviews when first conversing with an individual and when addressing small orlarge groups, the first few seconds are critical in setting the tone for how you'll be perceived. If she has an annoying regional accent, uses incorrect grammar, has a limited vocabulary, and if she has an irritatingly sharp piercing voice, sounds whiny or bossy or doesn't articulate her words clearly, it' s an immediate turn-off. This isn't someone who you would hire or proudly introduce to your friends and business associates. This doesn't mean that everyone should try to sound like a professional actor or broadcaster. All of us have qualities unique to our own way of speaking, our individual voiceprintas distinctive as our fingerprints. Our voice is very personal and an important part of our identity. Some natural characteristics of our voice may be very appealing. The idea is to take the voice with which you've been gifted and give it the very best sound that you can. With the right type of practice, by paying attention to the quality of your voice and by knowing how to properly express yourself,you' II almost immediately improve your opportunities in job interviews, social situations, in selling, and in running a meeting or addressing groups of people. Let' s say it again, it all begins with the instrument, your voice. If its sound and quality is flawed and needs improvement, that' s where you start. That' s what everyone hears whether in casual conversation or in making a major speech to a large audience. Pure vowel sounds, articulation, proper breathing, expressive speaking patterns, a pleasing vocal range, naturalness, all these will make you get twice the result with half the effort.
