Buy local. Reduce waste. Use the car less. Eat seasonal food. Avoid plastic. Buy second-hand. Repair. Consume less energy. Choose responsible products. As these recommendations accumulate, daily ecology can sometimes resemble an endless list of things we should do better. And when perfection seems unattainable, a temptation appears to do nothing at all. However, adopting a more environmentally respectful lifestyle can begin much more simply. Surveys by the ADEME show a nuanced situation: a large majority of French people consider that our way of consuming poses an environmental problem, while facing very different economic, practical, or organizational constraints. A useful ecological habit is first and foremost one that can be maintained. For some people, this might be taking the bike twice a week. For others, cooking more raw products, buying clothes second-hand, reducing impulsive purchases, or keeping their phone an additional year. A small sustainable change can have more meaning than a radical change abandoned after a few weeks. We spend a lot of time wondering into which bin to put a product. A question can be asked even earlier: did I really need to buy it? The ADEME recommends just that: before a purchase, ask whether the need is real, whether it is possible to wait, or if a similar object already exists at home. Buying less often mechanically reduces the resources used, packaging, and objects that will one day need to be disposed of. It is impossible to optimize everything. One can buy local vegetables and use a car occasionally. Buy a refurbished phone and take a plane to see family. Love flea markets and occasionally order a new product online. The daily ecological transition is also built with our constraints. The goal can be to identify the areas in which a change seems realistic and to start with those. The easiest ecological practices to maintain are often those that also improve life. Walking more can improve our physical activity. Buying less saves money. Cooking seasonal products can renew recipes. Repairing provides the satisfaction of keeping an object you care about. Borrowing a tool avoids cluttering the garage. Ecology gains by moving out of the realm of sacrifice. We probably do not need millions of people living a perfect ecology. We mainly need millions of people who gradually change some habits and maintain them over time.
