Dictadura cívico de afirmación de la dependencia del Perú al capitalismo norteamericano, en este momento hay un predominio de la oligarquía agroindustrial y maniobras legales que permitieron la reelección y prolongación de una dictadura, llamada LA PATRIA NUEVA.
The ozone layer is a layer in the Earth's atmosphere that contains high concentrations of ozone and absorbs ultraviolet light from the sun. It was discovered in 1913 and its properties were further explored in the 1920s-1930s. The ozone layer can be depleted by CFCs and other man-made chemicals which rise to the stratosphere where they break down ozone. Many countries banned CFCs in 1979 but it will take decades for the amounts already in the atmosphere to reduce, so damage to the ozone layer

The document discusses greenhouse gases and global climate change. It explains that while nitrogen, oxygen, and argon make up 99.9% of the atmosphere, greenhouse gases like carbon dioxide, methane, and nitrous oxide have a significant impact on climate despite small quantities. It compares the global warming potential of different gases to carbon dioxide and explains that carbon dioxide has the greatest impact due to its high concentration levels in the atmosphere, despite being a weaker greenhouse gas than others. The document also discusses natural and human-caused sources of several major greenhouse gases.
