Alaska - The population of polar bears are getting reduces, because the weather is getting hotter, and that is making that the glaciers are getting melt. That weather is afecting the live of polar bears and many of them are dieing everyday.

This decrease of polar bears cause that the food chain is breaking, because the polar bear is not able to eat as much as they need because, of the melting of the glaciers and they can´t go to the animals that it want to eat.

"The polar bears are dieing a cause unconsciousness of the people everyday contaminate the world by industries, cars or different ways, making this things happends" said a person that lives near the area of the bears.

Science and technology

1) This video is about science and technology, and what can happen if all technology dissapear in U.S.

2) The principal preocupation of this problem is that this can reduce jobs, scientific progress and threaten U.S. competitiveness.

3) That can produce many problems to the people and country

4) Yes, because I think that if aren´t technologic things is difficult to live and create jobs.

5) Yes I think so, like in investigations about science, or technology like T.V., etc.

What is science?

Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding¹. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.
