An Inconvenient Truth

An Inconvenient Truth talks on Al Gore and his travels to support of his efforts to educate the audience about the severity of the climate crisis. Gore says, "I've been trying to tell this story for a long time and I feel as if I've failed to get the message across." The film slightly follows a keynote presentation that Gore presented throughout the world. It intersperses Gore's exploration of information and predictions regarding climate changes and its potential for disaster with Gore's personal life story.It weaves in events that changed his world view, including his college education with early climate expert Roger Reveille at Harvard University, his sister's death from lung cancer and his young son's near-fatal car accident. For comic effect, Gore also uses a clip from the Futurama episode "Crises of the hot" to explain global warming. Gore refers to his loss to George W.Bush in the 2000 United States presidential election as a "hard blow" yet subsequently "brought into clear focus, the mission he had been pursuing for all these years."
I think that the film is very important and useful . everybody have to think about that and make our planet better to live.

An introduction to global warming

Global warming has been a serious problem since decades, and it keeps developing by the time. In previous era, the amount of carbon dioxide has increased and kept changing over the time due to the agricultural activities such as raising cattle and growing rice.

Human activities and nature influences are the two main reasons for causing a global warming. Human activities cause global warming such as driving cars, using electricity and heating our homes with oil. Moreover, green house gases which have a great impact on atmosphere and environment. As a result, having accumulated amount of green gases, trap heat on atmosphere and less goes back to out space. Furthermore, the serious problem that might be followed by global warming is the climate changes due to the less amount of heat in atmosphere. In addition, species are extinct and not able to adapt the new environment. Finally, changing in climate might cause a sever storms and floods.

My comment:

In my point of view, global warming is a serious problem because it has a big impact on our climate and species. Some of species do not exist anymore because they couldn’t fit into the new and changed environment. In addition, human beings will be affected by global warming in losing their normal environment and traveling to the different places searching for a good habitat. My advice is that human being should be careful in how to use the recourse in a suitable way.
