Food occupies much of my thoughts, maybe too much. Growing up in an Indian home, the kitchen was the place to be. The rest of the day simply orbited dinner, and the preparation of it. Sweets and treats materialised as the seasons changed, and Diwali - which usually falls around about this time - meant an influx of fried goodies rich in butter, sugar and salt. It’s not surprising then that an Asian heritage also brings with it a higher risk of heart disease, and I’ve got a nagging worry that my heart could benefit from a few changes to my diet. The trouble is, working on this magazine has made me deeply cynical. This is mostly useful. But when it comes to health, the constant influx of new food heroes…

eye opener

Forest floors CHENGDU, CHINA Construction of the Qiyi City Forest Garden was completed last year, but only a few residents have moved in.

In such a humid climate this needs to be once a week too, not a few times a year!” The humid climate has led to another problem with the vertical garden city: it is now infested with mosquitoes. “Mosquitoes love water. The balcony containers hold onto a lot of moisture and the area’s monsoons will not have helped. As…

ask a glassmaker

In response to the question ‘Is it possible to recycle plastics an infinite number of times?’ (Summer, p85) you wrote that glass and aluminium don’t degrade during recycling. This is not the case with glass. If you took all the bottles made in a container factory and kept feeding them back into the furnace, the glass would gradually become more and more viscous, and eventually the machines would be unable to produce any more bottles. I once was faced with the problem of running out of glass in a tank furnace, which was never emptied but topped up with ‘batch’ (raw materials) weekly. As we kept gathering the glass it became more difficult to work with and the quality worsened. The resulting products then cracked during cooling because the glass…
