6 Human Activities For example: CO 2 emissions to the atmosphere: cars, electricity, water Deforestation – construction Contamination other emitted gases like Methane

7 Global Warming

8 Lake Chad Was the 6 th largest lake in the World! A study by U. Wisconsin-Madison and NASA's EOS, the lake is now 1/20th of the size it was 35 years ago. W. Africa (Chad, Niger, Nigeria, & Cameroon), the region has suffered from an increasingly dry climate, experiencing decline in rain since early 1960s. We are causing Extreme poverty in Africa due to our emissions which accounts for 25% of all world emissions compared to Africa’s 3%.

9 The Ethical Dimension of Climate Change "If sea levels rise at the rates they are predicting, we may see hundreds of millions of refugees" "Where will they go? Who will take them in? What does it mean about immigration regulations?" "The future will be catastrophic for all communities, for all countries, but particularly for those who have already been identified as particularly vulnerable to the impacts of climate change," Specially small island states which might disappear entirely under the rising ocean. "It is a moral obligation, beyond political obligation or economic obligation, to help countries like Tuvalu and small island developing states, and of course the least developed countries," "We have to do something urgently."

10 Social impacts Sub-Saharan Africa produces about 3% of the world’s greenhouse gases, yet… Its climate and ecological systems have already been altered by global warming and will undergo further damage in the years ahead. Demonstrators in Nairobi, Kenya, protest failure of developed countries to curb emissions of greenhouse gases. www.un.org

11 A 2006 report by economist Sir Nicholas Stern suggests that global warming could shrink the global economy by 20%!

50 Styrofoam Generate many toxic gases & CO 2 during their production. Are NOT biodegradable, are prohibited in many cities in the U.S.

51 Evita uso platos, cubiertos y servilletas sanitarios (Styrofoam®, Plásticos o Papel) *Vajilla = $7,000 ahorro mensual en el RUM según un análisis de costo reciente. Styrofoam cuesta $$$…

52 Eat less Meat Methane gas is 20x stronger than CO 2 Could be captured and used as fuel. Landfields produce it. Cattle farms produce it.

53 According to a 2006 study by U. of Chicago; Eating a vegan diet prevents the equivalent of 1.5 tons of CO 2 emissions every year, more than the 1 ton of CO 2 emissions prevented by switching from a typical large sedan to a Toyota Prius. So why does meat cause so much global warming? Growing feed for farmed animals requires intense use of synthetic fertilizer, which releases N 2 O– a far stronger greenhouse gas than even CO 2. The tens of billions of farmed animals of the world produce massive amounts of flatulence and liquid manure, which release large amounts of methane into the atmosphere as well as forming nitrous oxide, both of which are powerful green house gases. Heating buildings that house farm animals – emission of green house gases "Rearing Cattle Produces More Greenhouse Gases Than Driving Cars, UN Report Warns," UN News Centre, 29 Nov. 2006. “…raising animals for food generates more greenhouse gases than all the cars and trucks in the world combined”. 2006 U.N. report

54 http://www.usatoday.com/news/graphics/plastics/flash.htm

55 The Water link… To produce 1 lb of MEAT –You need 1,000-12,000 lbs of Water! To produce 1 lb of potatoes, wheat, corn and rice –You need 60, 108, 168, 229 pounds of water, respectively

56 La simple verdad Según un estudio en 2006 por la U. de Chicago; Cambiar a vegetariano ahorra más emisiones de invernadero (1.5 tons CO 2 annual) que cambiar de usar un auto grande a un auto híbrido como Toyota Prius! (ahorro 1 ton de CO 2 anual)

100 Living Green haz la diferencia deja tu huella is about changing our patterns of consumption and seeking out greener, natural and ethical alternatives to every conceivable type of product and service. It’s about buying more wisely, consuming less, wasting less, thinking through the consequences of our purchases. It’s about reducing our impact on the planet and our fellows by making choices that are better for us, better for the environment, and better for other people. It doesn’t preach, but it does show that there is a way forward to one-planet, sustainable living, a means to combat climate change and a way to protect the world’s scarce resources. http://www.greenguide.co.uk/

102 It’s our moral responsability… Let’s use its resources efficiently so that we can all benefit from it. We only have ONE planet. We only have ONE planet.

103 ¡No comas pesticidas! …ni hierbicidas, fertilizantes químicos o insecticidas. Estos químicos dañan la capa de ozono y emiten gases de invernadero.

104 ¿Por qué Orgánico? Son productos sembrados sin fertilizantes químicos, plaguicidas, herbicidas ni insecticidas. –Sólo composta e insecticidas naturales. Los pesticidas artificiales contienen Bromuro: –el cual daña la capa de ozono y empeora el Calentamiento Global. Los fertilizantes artificiales contienen Nitrógeno: – el cual es un gas de invernadero y empeora el Calentamiento Global.

105 Productos de Limpieza Usa productos de limpieza que no dañen el entorno natural. Evita usar cloro, y otros productos que dañan el ambiente y a la larga nos envenenan nuestra salud y el entorno natural (fauna, flora, cuerpos de agua), causando asma, y otras enfermedades. Ahorras$$ usando: vinagre, polvo de soda, borax, limón para limpiar.

106 Evita bolsas plásticas! Las bolsas plásticas están hechas de petróleo, y tardan más de 100 años en biodegradarse. Las prohibieron en Uganda, China e Irlanda. En China se ahorrarán anualmente 37 millones de barriles de petróleo debido a prohibición de las bolsas plásticas. Evita también las bolsas de papel, contribuyen a la desforestación Ambas afectan mucho al ambiente y muy pocas se reciclan. Muchas tortugas mueren al comerse las bolsas Además son un gasto innecesario para los comercios. Utiliza bolsas de tela, cáñamo u otro material que se pueda usar muchas veces e incluso lavar fuera necesario.

107 Usa bolsas re-usables Las bolsas plásticas están hechas de petróleo, y tardan más de 100 años en biodegradarse. Las prohibieron en Uganda, China e Irlanda. En China se ahorrarán anualmente 37 millones de barriles de petróleo debido a la prohibición de las bolsas plásticas. En algunas tiendas si usas su bolsa de tela te devuelven dinero. (ej. Vitamin World te devuelve $1 cada vez que usas su bolsa de canvas en compras de $10 o más). Anualmente, miles de tortugas, anguilas y otros animales mueren debido a que se comen las bolsas plásticas y vasos plásticos creyendo que son agua viva.

108 DRY Cleaning Dile NO al: Utiliza muchos químicos (percloroetileno) que dañan el sistema nervioso, afectando al trabajador de la lavandería y a tu salud. Además contaminan el ambiente. Se ha relacionado a incidencia de cáncer www.ehponline.org/docs/2005/8425/abstract.html

109 Anti-bacterial Dile NO a lo: Contribuye a que las bacterias creen resistencia a antibióticos (“super bugs”) Antibacterial soaps are helping to promote growth of resistant bacteria, according to a 2000 World Health Organization report.

110 Desechable Dile NO a lo: Aumenta los desperdicios en el vertedero, por lo tanto a más gas metano! El metano atrapa 20 veces más calor en la atmósfera que el CO 2

111 RECICLA BIEN: NO sorbetos NO vasos Sólo plástico #1 y #2
