NUNC! | Nuevo Humanismo, Ciencia, Cultura y Comunicación en la era digital | París, 14-15 de noviembre de 2011 Finding seclusion in a world of 7 billion Updated Fri 4 Nov 2011, 6:08pm AEDT Escaping in a world of 7 billion people is becoming increasingly difficult, but in Australia - one of the least densely populated countries - seclusion still exists. The global population passed the 7 billion milestone this week and is expected to hit 9 billion by 2050. Hayman Island on the Great Barrier Reef is about eight kilometres in circumference, with a population of just a few hundred. Photographer Lisa Burns, 27, has lived there for the past two years. Here she paints a picture of what it's like in one of the Earth's few remaining pockets without people. I moved over with my partner. We live in a studio apartment, it's like a hotel room, we don't have a kitchen or anything like that but we've got a balcony which looks over the ocean and the reef. The island is quite small - it's about eight kilometres in circumference - so we can't go to many places but we go for bushwalks and sunset walks when it's low tide and things like that.
Scorecard Home the free encyclopedia 7 challenges for 7 billion Updated Thu 3 Nov 2011, 9:36am AEDT This week the world's population ticked over to 7 billion. By 2050 that number is expected to grow to 9 billion. From water shortages to rising sea levels, experts from the University of New South Wales and the University of Melbourne paint a grim future for life on Earth. They forecast dramatic changes unless significant steps are taken to curb population growth. Here seven academics outline seven challenges they say a population of 7 billion must confront. Is it all doom and gloom as they suggest, or do we have a brighter future? Climate Australia is one of the most affluent and also the most effluent nations on Earth. What we're putting into the atmosphere really constitutes an unprecedented experiment with our planet that is going to lead to changes that haven't been seen in millions of years. Water Access to fresh water in Australia, the driest inhabited continent, is incredibly difficult. Energy Economy Ageing population Birth control Food security

Blog » The Top 10 Plants for Removing Indoor Toxins Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside homes, indoor public spaces and office buildings. The indoor pollutants that affect health are formaldehyde, Volatile Organic Compounds (benzene and trichloroethylene or TCE), airborne biological pollutants, carbon monoxide and nitrogen oxides, pesticides and disinfectants (phenols), and radon. These pollutants contribute to ‘sick building syndrome’, which causes symptoms ranging from allergies, headaches and fatigue through to nervous-system disorders, cancer and death. Through studies conducted by NASA, scientists have identified 50 houseplants that remove many of the pollutants and gases mentioned above. More information on this study as well as references and details on specific chemicals can be found on Dr. Dr. 1. Also called the “Butterfly Palm”.
What is Urban Sprawl What is urban sprawl? What are its causes and effects? Read on for the answers... People have always desired to live comfortable lives. A life in which they have all the facilities for themselves as well as their families. In their quest for it, people have migrated from their native places to areas where they can find employment. Today, the scenario has not changed much. Causes A typical feature of an urban sprawl is families who live in their own independent houses, with all the modern facilities and own cars to travel to work in the main city area. Another important reason behind urban sprawl is the peaceful life that they promise. If you take a specific case, the government policies in United States of America have not done much to check this phenomenon in the country. Effects There are both positive as well as negative effects of urban sprawls. As for the positives, there are people who link urban sprawl and development to one another. This is in short about urban sprawl.
