Osnabrück (dpa) - The Greens in Lower Saxony advocate a waiver of the rising of gas-filled balloons. «Raised balloons land in the vast majority of nature. Birds and other animals eat the soft balloon remnants and then starve to death with a full stomach, "said Greenland Chief Anne Kura of the" New Osnabrücker Zeitung ". Balloons made of natural latex are therefore no real alternative. According to the NOC, Kura reacts to a decision by the city of Gütersloh. For reasons of environmental protection, flying air balloons should be avoided at city events.
