I don't think the numbers scale linearly. A single dollar probably does nothing to contribute to better animal welfare. It takes a threshold of money to start being impactful, and over a long time period to inflict noticeable long-term change. The impact of a single donation also probably doesn't have as many consequences on the individual and societal level as investing a year to change habits, learning new recipes, thinking about nutrition and health and animal welfare, and inadvertently also talking to friends and bringing up demand for restaurants to expand their vegetarian/vegan options. Lastly, the choice doesn't have to be a binary one. It is possible to reduce consumption to bring average consumption down.
