Cannabis tyres

I started my post-graduate scientific career as a plant biochemist (phytochemist to be more precise). Once talking to a geologist about how fascinating plants are, he replied, “plants just get in the way of the rocks,” and so I guess your interests very much depend on your viewpoint.

Now is not the time to be complacent about plastic pollution

Some of us are old enough to remember when a polyester suit was fashionable. Although still used in clothing today, polyester has diminished in appeal since the 1970s.
