а)
I try not to throw away food so I do it very rarely. I think it is a shame to throw food away so I mostly buy fresh food in small quantities to cook the same day. I only throw away food if it is past its sell by date. I throw one or two items of clothing away about every six months when something is worn out. I try not to throw electrical goods away, but when something is broken I take it to a recycling centre.
b) I think people could reduce food waste by buying and preparing food in smaller quantities. We could reduce electronic waste by either taking the item to a recycling centre or repairing it and as for clothes we could also try to mend worn or torn pieces of clothing or use the material to make something else. Of course, there is also the option of donating old clothes to charity.
