             Luis Suárez joins anti-racism calls after Dani Alves banana incident

      The Barcelona defender Dani Alves has sparked a social media campaign against racism in football as support flooded in from fellow professionals for his decision to eat a banana thrown at him by an opposition fan.

      Luis Suárez, Neymar, Hulk, Mario Balotelli and Sergio Agüero were among those who posted pictures of themselves taking bites out of bananas in tribute to Alves' actions in his side's La Liga match at Villarreal on Sunday.

      The Fifa president Joseph Blatter has branded the abuse directed at Alves an "outrage" and promised zero tolerance towards discrimination at the World Cup, while Villarreal took swift action by identifying the culprit and handing him a lifetime stadium ban.

      Alves' response to the banana being thrown on to the pitch in front of him as he prepared to take a corner was to nonchalantly pick it up, peel it and take a bite before continuing with the game. The 30-yearold, who has been the victim of racist abuse before during his time in La Liga, said: "You need to take these situations with a dose of humour."

      Players across Europe paid homage on Twitter and Instagram, including Suárez, who served an eight-match ban for racially abusing Patrice Evra.

      Alves's Barça and Brazil team-mate Neymar led the way after posting a picture on Instagram of himself holding a banana, while writing "We are all monkeys". Balotelli, Milan's former Manchester City striker, posted a picture of himself in a similar pose.

      Suárez posted a picture on Twitter of himself and Liverpool team-mate Philippe Coutinho taking bites out of bananas, along with the words: "#SayNoToRacism #WeAreAllMonkeys."

      (...)

      Barça gave their player their "complete support and solidarity" and thanked Villarreal for their "immediate condemnation" of the incident. Villarreal later revealed they had, with the help of fans, found out who the culprit was, had withdrawn his season ticket and banned him from the El Madrigal stadium for life.

                  LANDFILLS AND THE INTRODUCTION OF NANOMATERIALS IN WASTE

      Waste disposal on land (dumping) and landfilling remain the most prominent waste management techniques used ______. The standards and practices for this type of waste disposal vary greatly ranging from uncontrolled sites to highly specialised and controlled engineered landfills. The potential ______ of contaminants through landfill gas and leachate is largely dependent on landfill design, site conditions and the sophistication of the control measures in place, ______ landfill gas recovery and leachate collection and treatment systems.

Modern engineered landfills use ______ barriers, with few relying on natural barriers, to line the bottom of a landfill and incorporate collection systems for both leachate and landfill gas. The purpose of these collection systems is to capture and treat leachate and landfill gas; ______ preventing the migration of leachate into ground/surface water and the release of untreated landfill gases to the atmosphere. An un-engineered landfill would be considered an uncontrolled system due to the lack of environmental controls, potentially resulting in significant environmental exposure of contaminants.

      Because of widespread use of ENMs in a broad range of products, it is possible that some ENMs ______ through landfill gases; however this report will primarily focus on ENMs that may be present in landfill leachate, as this is considered to be the primary means by which ENMs could be transported______ a landfill. Characterisation of landfill gases to identify the presence of ENMs ______ an important area for further research.

      Landfill leachate is generated when rain passes through the waste mass and by the liquid generated due to the breakdown of waste ______ the landfill. The composition of leachate is extremely ______ depending on the type of waste landfilled, the quantity of precipitation, the construction and operation of the landfill, the age of the landfill and other factors such as pH, temperature and microbial populations.

                                                                              (…)

ENMs = engineered nanomaterials.

           The Environmental Pillar of Sustainable Water: Ecological Services

Across the globe, increased demand and water mismanagement have put stress on water services. As a result, there has been a growing societal recognition of the need to look at sustainable solutions that allow for everyone to have access to clean water. There is growing recognition of the importance of ecological services (benefits arising from the ecological functions of healthy ecosystems) as part of a management strategy in new approaches. Ecological services imply that nature can also play a role in providing safe drinking water. Whether through source water protection or natural filtration, the environment can work in concert with technology to provide water in a reasonable, sustainable fashion.
