The green trend and sustainability is one of the biggest trends for the rest of our lives, and we are seeing it embraced by people and businesses all over the world. What's interesting is that governments are now getting into the act, making laws and pronouncements that don't just make greening a social trend, but a legal one as well. Now the city of Lisbon, in Portugal, is looking to call itself the world's first "Zero Waste" capital, which means that the city will send nothing to its landfills. Everything that can be recycled, will be. Everything that cannot be recycled will be used as fuel in incinerators to create energy. And it goes further. The Zero Waste movement also aims to re-use excess foods and leftovers that are perfectly adequate for consumption but which would otherwise be thrown away. In partnership with a private organization, the city will collect untouched leftover food from restaurants and redistribute it to charitable organizations that help feed the hungry. Of course, that is not the first program in the world of its kind. Others like City Harvest in New York do something similar. But that's why it is a trend. The concept of greening and recycling continues to grow worldwide, and we are seeing initiatives on a daily basis that prove that this trend is only getting stronger.
