参考解析：

细节理解题。根据第四段第三句“However, we can start a personal revolution against consumerism. How? By consuming less.”可知我们可以通过减少消费来开始一场抵制消费主义的个人革命，所以A项正确；根据第四段倒数第二句“We can ask ourselves what experiences bring us the greatest satisfaction”可知，并未提到购物可以带给我们巨大的满足感，所以B项错误；根据第四段第一句“The environment we live in encourages us to have packaged experiences.”可知，我们的生活环境会促进我们购物，所以C项错误；根据第三段第一句“it is likely that non-consuming experiences like these will be our most important memories”可知，非消费体验才会成为我们最重要的记忆，所以D项错误。故选A。
