Inconvinient thoughts

Thoughts of the past months:
What to belive...
Global warming and plastic bags- up to know I thought it is important, was on of those to care about usage of elecrticity, going shooping with own bags, using plastic bags for sth more not to be simple rubbish. but is it worht it?

how hard it is to assess whether sth is white or black:]
