T =What do they mean?= 

Famous quotes
[|Margaret Mead American Anthropoloigsts] TRATA DE DECIR QUE NO PODEMOS VIVIR EN UN MUNDO O EN UN AMBIENTE DESTRUIDO, CONTAMINADO, TODO SERIA RARO, TRISTE, GRIS, SI SEGUIMOS QUE LA TIERRA SE ENFERME MAS LA CONTAMINACION VA HACER TAN GRANDE QUE NO VAMOS A PODER TENER VIDA ANIMAL, VEGETAL, EL AGUA SE ACABARA, POR TAL MOTIVO DEBEMOS CUIDAR NUESTRO AMBIENTE
 * “We won't have a society if we destroy the environment”


 * Pollution problems**

Make a list of the ecological problems facing Earth.

Ls tala, la quema la basura los quimicos que bota las industria que contaminan el aire y agua la sobrepoblacion la poblacion no contribuye con la limpieza


 * Write an X next to the ones that are affecting Venezuela today **

la mentalidad que poseen los cuidadanos de no conservar el ambiente la sobrepoblacion muchos carros sustancia quimicas que caen en nuestras aguas mucha basura en las calles la anbundancia quema que ralizan > > > La basura, ya que primero que adquiere un aspecto feo, su olor contamina el aire y cuando la basura se descompone bota quimicos que contamina el suelo > > > la abundancia de los carros ya que botan dioxido de carbona provocando contaminacion en el aire > > > la tala que cortan nuestros arboles, ellos nos produce oxigeno y proteccion contra los rayos del sol, ademas, en la actualidad lo necesitamos por el sobrecalentamiento global
 * **Choose three (3) problems that you consider to be the most important affecting the country. Give your reasons.**

=It`s heating up! Global warming!= 

The Global Warming quiz
Write any new information you learnt from the quiz: lo unico que aprendi es que el dioxido de carbono se matiene en la atmosfera durante 100 años


 * Impacto en el futuro**

Los huracanes y otras tormentas pueden llegar a ser más fuerte.

Las inundaciones y las sequías serán más comunes

enfermedades se extenderá, como la malaria transmitida por mosquitos

Ecosistemas al cambio de algunas especies se trasladará más hacia el norte o tener más éxito, otros no serán capaces de moverse y podrían extinguirse


 * Impacto presente**

se derrite los polos norte y sur

se extienge el ecosistema

la precipitacion ha aumentado

el nivel de agua ha aumentado considerablemente

The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. Photograph by Ilya Naymushin/Reuters/Corbis || ||

And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move. Some impacts from increasing temperatures are already happening. Other effects could happen later this century, if warming continues. Source for climate information: IPCC, 2007
 * Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
 * Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
 * Sea level rise became faster over the last century.
 * Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
 * Precipitation (rain and snowfall) has increased across the globe, on average.
 * Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
 * Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).
 * Hurricanes and other storms are likely to become stronger.
 * Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
 * Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
 * Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
 * Some diseases will spread, such as malaria carried by mosquitoes.
 * Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier. Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay. He fears that if sea ice disappears, the polar bears will as well.
