I watched it and felt guilty afterwards, but what can you do? I know people who are vegans and they all seem to eat a lot of processed foods. I prefer to eat butter and cheese than margarine and substitutes, but I feel guilty supporting the dairy industry.
I avoid man made fibres, but I know that cotton is a huge drain on resources. I recycle, but I'm told much of that will end up in landfill.
I try to buy less, and I do buy second hand here and there, but it's quicker to order new.
There's always something more to do, but I suppose so long as we're doing our best, that's better than doing nothing. For most people, eating less meat is probably a more realistic goal than eating none.
