If something breaks, rather than immediately throw it away and buy a new one, perhaps try and fix it. White goods such as ovens, washing machines etc, for example, are easily fixed, with spares readily available. Thanks to the internet, spares for all kinds of things can be easily obtained, together with useful online videos of how to repair almost anything.
Every new product requires materials, labour, transportation and energy, which all have a carbon cost; not to mention that the old item will go to landfill to pollute our environment. Fixing something can be fun and satisfying, and it will even save you money.
Upcycling is also a great alternative to buying something new, and it is particularly good with furniture, where a quick coat of paint, or a quicksand and some oil can transform something old, rather than throwing it away to buy something new. If you don’t have the energy to repair or upcycle, then look at buying recycled or second-hand items – less new things and less old things going into landfill.
