One of the things that I often hear is that people’s individual actions wont make any difference.
But a lot of individual actions add up over time
In an article on Yahoo finance estimates an $83Bn hit to US GDP this year https://finance.yahoo.com/news/foreign-boycotts-could-register-up-to-83-billion-hit-to-us-gdp-in-2025-goldman-sachs-says-203157185.html
So go ahead and make those small changes – it all adds up.
