Sustainable shopping does not need to be complicated. If you take into account just a few things, you can reduce your ecological footprint significantly:
Support local farmers and reduce your carbon footprint!
Seasonal produce tastes much better and contains more vitamins than vegetables from energy-intensive glasshouse production.
Organic products are subject to stricter controls and policies e.g. on pesticides.
Meat production is a significant part of global CO2 emissions. Already one meat-free day per week is a significant contribution to the protection of the environment.
Farmer’s markets not only provide a platform for local farmers, it is also hard to find plastic packaging there.
More and more supermarkets implement emission reducing measures. There might be one near you, it’s worth asking.
