Global warming is a problem which is affecting the entire world; however, people don’t realize the problems that Global warming can provoke in the human population. It is becoming to be a real thereat for the world. Earth’s temperature has been changing since the past century, but it has accelerated during the past two decades. This change of temperature is named Global warming. Global warming is affecting human life, for that reason, it is very important that people know What it is? how it's caused? and what needs to be done to stop it? Some consequences of Global warming already has been observed into some alterations in world, such as: temperatures have been at a record high for a decade, coastal shorelines have retreated, island nations are losing habitable land and glaciers are melting on five continents. I consider indispesable that people get knowledge about Global warming, so they can help to prevent some Global warming’s dangers, and people could begin to be part of a solution to problem.

Humans live the resource of dead organic matter, and humans have found dead organic matter below ground, in the form of oil, gas and coal which exist as result of the fossil remains of plants that lived long ago. However, at moment, population increase dramatically, for a short time, inevitably the resources dwindles and the population collapses. Precisely, it has succeeded in the world. Fossil energy has propelled the development of the industrial age and allowed population to explode. So, as product of the industrial age has produced in the atmosphere over increase of carbon dioxide (CO2) which is threatening to destroy the world. The atmosphere provides us oxygen to breathe and it controls the heat balance of the world, too. However, now the atmosphere is relativity small in mass compared whit the ocean, so it provokes that changes induced by humans can affect dramatically to the atmosphere.

Global warming is the increase in the average temperature of Earth’s atmosphere and oceans. And, it has basically been provoked by increase of amounts of carbon dioxide (CO2) and other gases. Global warming is a problem which is attributable to human activities. Carbon dioxide and other gases that contaminate the air accumulate in the atmosphere, forming a thickening blanket which traps the sun’s heat and provokes global warming.

This climatic change would provoke worse consequences for sever million human who live in poverty or are bordering on it. Poverty is the source of pollution, but it is also generated by a world in which human beings are insistent on maintaining their lavish lifestyles.
