Last weekend some friends of mine and I took a trip to the North-West of Massachussets to see the leaves which have changed their colors. All over the world people talk about the autumn in Boston. In the following pages I would like to talk about a topic which should concern everyone of us. It is a delicate topic which has been present as long as human beings have existed and it will last forever. The following day we took a boat trip to see the Los Glaciares National Park, where many glaciers formed hugh lakes. Many ice bergs were floating in these lakes and some of them had bizarre light blue colors. |
