Waste water? Did you miss the day at school where they explained how rain works?
I've just spent a minute googling. Every reference I found says "bucket or donate", including wikipedia. Any sources to back up this version?
The fact that I got the picture from Facebook and have seen it posted multiple times would suggest it's a very popular misconception. Not to mention the "bucket or donate" slogan.I can point you in the direction of a lot of people who also misunderstand.
Are there other causes experiencing a downturn in donations?
You are going to have to struggle by for yourself.
1. Almost all water poured onto the ground will evaporate and later return as rain, and thus not be wasted at all.Is it not a waste? Could it be put to a better use?
