The Climate Challenge
Food &Environment The climate challenge Pope Francis’ encyclical Feeding Home the world The Climate Challenge Pollution is one of the most damaging phenomena caused by men: the introduction of chemical substances in the air puts in danger the life on our precious planet. Deforestation is the disappearing of forests caused by natural phenomena (fires, acidic rains) and human actions. A flood is an overflow of water which is due to continuous rains: it causes damages to economy and agriculture. Wind turbines are a modern device able to transform kinetic energy into electricity. Solar panels are able to absorb solar rays to generate electricity. Although they are really expensive, lots of countries use them. There are several small actions in everyday life which we should do to try to face the problem: 1. Walk or ride your bike whenever possible 2. Use public transport 3. Carpool to school or work 4. Get regular maintenance on your vehicle 1. Choose local food whenever possible. 2. Reduce or eliminate the consumption of animal products. 3. Choose organically grown fruits and vegetables. 4. Grow your own fruits and vegetables. 5. Buy used items whenever possible. 6. Recycle everything that you can. The garbage submerges our planet, which is changing itself into a faint memory of what it used to be. The earth, our house, is going to become an immense deposit of garbage. We are not God. The earth is a gift for us and we must preserve it. If we do not change this trend and our habits, this century will witness climate changes and the destruction of ecosystems. “I urgently invite you to renew the dialogue about the way according to which we are building the future of the planet.” (Pope Francis) Food is a global challenge for the 21st century. More than 800 million people are suffering from malnutrition and 1.4 billion are overweight or obese. “We are what we eat”, wrote the philosopher Ludwing Feuerbach. There is an inseparable unity between mind and body. By identifying genes and manipulating them, scientists hope to create new crops that will help us face the challenges of global warming and population growth. The world produces enough cereal to feed between nine and eleven billion people. Less than half of these are destined to human consumption and about a third of all food production is used in the production chain. Despite a significant increase in food production per capita over the past 5 years, there are still an estimated 805 million people in the world who are chronically hungry. “We can survive as a species only if we live according to the biosphere’s laws. The biosphere can satisfy everyone’s needs if global economy respects the limits imposed by sustainability and justice.” (Vandana Shiva) “In nature's economy the currency is not money, it is life.” (Vandana Shiva) Sharing is everything on the Earth. Nothing is self-sufficient, water and air are united in life and for life. Our life is linked to innumerable living beings that have inhabited the Earth since four billion years ago. Our agriculture has become oil-powered. Our world’s clock now beats to the rhythm of indefatigable machines. Over 50% of grain traded around the world is used for animal food or biofuels. The melted water causes the movement of the ice and the rising of the sea level. IT'S TOO LATE TO BE PESSIMIST, A SINGLE HUMAN CAN KNOCK DOWN EVERY WALL. “This is a hibernated garden of Eden. A place where life can be kept forever, whatever happens in the world.” Progetto realizzato dalla III EU del Liceo Scientifico “Publio Virgilio Marone” A cura della Prof.ssa Margherita Tirelli Presentazione realizzata da: Conforti Alessandro D’Ambrosio Antonio De Girolamo Luca Grimaldi Salvatore
