Ron Gutman, the founder and CEO of HealthTap, a personalized health-info site, gave the speech about the power of smiling. As everyone knows that smile is good for our health; he gave the supporting data and facts about that statement. For instance, there was a study about the relation between student faceâ€™s photo in the yearbook of UC Berkeley and the studentâ€™s success and well-being throughout their lives. Another study showed that the span of the peopleâ€™s smile could predict the life span of peopleâ€™s life; people who have beaming smile could have 79. 9 years of their life span while only 72. years for people who do not smile. W e naturally smile to express joy and satisfaction; one smile could generate the same level of happiness equals to 2,000 bar of chocolate; even the people in the tribe who are isolated from the modern world also smile. Also smiling could make us healthier since it reduce stress-enhancing hormone like cortisone. And the message behind smiling, which is happiness, could be passed to the others as well. When you smile, you look and feel good. And when other people see you, they would mimic the smile and feel good too, as this would go on as a cycle. In conclusion, smiling has many aspects of benefit, so letâ€™s SMILE. http://www. ted. com/talks/ron_gutman_the_hidden_power_of_smiling. html Amit Sood: Building a museum of museums on the web Art Project is the great idea created by Amit Sood. It is the project of creating a 3D virtual image of the museum on the website which allows the people from any class of society to get access to the artworks from any museum through the website www. googleartproject. com. Users can move around and look at the artwork one by one by simply just clicking. And it is much faster to move from one end to another room of the museum by one click. Besides, the images of the artworks in the museum have huge size i. e. 10 billion pixels. It is amazing because user could notice some small spot of details e. g. painting crack that is impossible to notice when they carefully look at the real artwork in the museum. Moreover, user could create his/her own favorite collection album regardless of who they are. http://www. ted. com/talks/amit_sood_building_a_museum_of_museums_on_the_web. ht
Many centuries ago people lived in harmony with nature because industry was not much developed. There was no ecological problem until people built lots of plants and factories which sent wastes into the air, water and land where they didn't disappear but lasted forever in one form or another. Nowadays people live only according to their wants and requirements, they ignore the laws of nature. That's why today the contradictions between man and nature are dramatic. People are slowly destroying the nature environment around them.
Today we are anxious about the state of the air we breathe because every year world industry throws out into atmosphere about 1 000 million tons of dust, smoke and other harmful substances and people of many cities suffer from smog. | Another reason why there is such high level of air pollution in large cities is because of car exhaust fumes from very intensive transport. A great number of plants get used to dump poisonous chemical wastes in rivers, lakes and seas that has led to polluting water and killing fish life.
At present time pollution from sinking ships and tankers with oil is increasing and there is a strong destruction of sea life. We face the fresh water supply problem today because of the depletion of water resources and the disruption of water cycle. Speaking about atmosphere we should mention ozone holes which are result of air pollution and their increase can lead to the destruction of the whole great chain of life of our planet.
The pollution of the air, oceans, seas, rivers and lakes and the destruction of the ozone layer could lead our planet to a global catastrophe. But the most terrible catastrophe of our age is the Chernobyl disaster which has resulted not only in atomic explosion but has brought death to 300 thousands hectares of farm lands and has affected the lives of millions of people. The radiation doses have affected and will continue to affect the health of people living in contaminated areas.
The Earth is our home that's why we must take measures to fight land pollution and keep our environment clean; we must plant trees and flowers and take care of animals, we must not throw our wastes into the rivers. In many countries environmental protection organizations such as â€œGreen Peaceâ€, â€œFriend of the Earthâ€, â€œWorld Wild Life Fundâ€ are set up which try to put pressure upon the governments that don't care for ecology in their countries. The humankind will be able to survive only if we all realize that environmental protection is our universal concern.
