Yes, we really need to start being less dependent on fossil fuels and also use less ‘disposable’ items. Plastic packaging and other items that are one use and disposable (plastic bottles, plastic cutlery, item packaging etc), is very unsustainable 🙁
Yes, we need to be more sustainable and only use recyclable materials, reduce packaging and waste production. Switch to nuclear power and renewable fuels where possible. Have reward schemes for car/lift sharing, using the bus or cycling/ walking to work.
There is a lot we can do but it will take a global attitude change to make a difference in the long term.
