One might expect that the ever?growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday?makers. Indeed, a rosy picture is painted for the long?term future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rock?bound Pacific island is advertised as the ‘last paradise(天堂) on earth’．

However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of sea?side holidays, over?crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.

Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday?makers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.

Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one?time farmer is now the servant of some multi?national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.

Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.

The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning world?wide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.

In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.

However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.

“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, self?harm, low concentration and poor performance at school，” she added.

While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.

Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.
