This illustrated talk looks at mankind’s dependence on plants – we may not be aware of it, but rarely a minute goes by when something we’re doing would be impossible without the help of plants. They are an essential component of all life on this planet but an increasing global population is putting enormous, and unprecedented pressure, on this essential resource.
Can careful management or exploitation of these resources enable us to keep up with growing demand? This talk explores what we, as individuals, can do to help the sustainability of food security for future generations.
