They know that [|greenhouse gases] make the Earth warmer by trapping energy in the [|atmosphere]. Compare and contrast videos: The 2 are talking about the changes around the world because of the global warning but the video of the 2008,in that video Algore want to make people to think more about the effects about global warning. meanwhile the first talk about ideas to reduce the impact of pollution. Summary and opinion: This video try to makes us think in all that changes that pass because the increase of the CO2 in the planet and that cause that the temperature of the earth and doing forestall fires and that the glaciers melt. I think that the global is the results of the bad actions of humans along all the time like all the weapons and the bad use of the natural resources. 5 reasons of pollution: noise pollution: Noise has adverse effects on people and the environment. Noise causes hearing loss, interferes with human activities at home and work, and is in various ways dangerous to people's health and well being. = Toxic Waste: Pollution prevention consists of all those activities that reduce the generation of hazardous waste. Many terms are used to describe these activities: waste minimization, waste reduction, source reduction, waste diversion, pollution prevention, recycling, and reuse. = = Air pollution : results mainly from the incomplete combustion of several fuels, such as coal, petrol and wood. The primary sources of pollution from combustion are furnaces in factories, engines in vehicles and burning of trash. = = Water pollution : has been a problem for a very long time. There are many different kinds of water pollution. Water pollution causes many problems with the living plants and animals in the water. = = Industrial pollution : in the mid 19th century, the earth has experienced a very rapid increase in the amount of pollutants in the air and the water, due to emissions from automobiles, factories, chemical plants and other manufacturing methods. =

**//__ I have good and bad news __//**
In the world we have some problems but one is the more problematic in this time, I am about the well know global warming, in this years we have said, is not a big deal, we can life with this, some people said that is just man made but what we have to know is that is a cycle that pass many years ago, but we do that the time that we have before a new ice age or something worst is getting short because that we increase the levels of carbon dioxide in the enviroment and the exesive cut of trees in the forests. We can do things to make that the global warming can stop like planting any tipe of plant, recycle things like the use paper, plastics and other things but you can also get those things to specials places to be recycle. They are bad efects from the nature, the are examples like acid rain that contaminate plants, rivers an us, the are the the huge pieces of ice that are melting because of the green house effect that mantain the ultraviolet rays from the sun into the atmophere because of the co2(carbon dioxide) that distroy the ozone layer little by little.
