Everything is always so positive here on steem. There are many problems that need facing in this world and steem has an important role to play. This is the best source I could find to point out a serious problem in our environment. Dolphins are dieting and many other creatures are as well. No it is not man made global warming unless you want to talk about geoengineering.
Edit: Congrats for what it is worth.
