From a scientific point of view, a toxin is a very specific type of poison, one which is produced via living cells. For instance, a poison produced by a spider would be considered a toxin. A manmade poison, on the other hand, would not be considered a toxin.
In the modern world, most people think of toxins in a more general sense, simply as substances which are poisonous to humans and/or animals. They refer to poisons which are produced by living cells as bio toxins or natural toxins.
Work in waste management is increasingly technical. This work involves both collection, transport and sorting of waste, then either recycling or "smart" treatment of waste to minimise any environmental impact.
The world of fungi is a critical part of the ecology; but often unseen, misunderstood and unappreciated.
Our mushroom, plant pathology and microbiology courses can help change your perception of the world of fungi.
For the home vegetable garden, the most widely grown beans are usually common (green) beans, runner beans, and broad beans. The common bean is known by a number of other names including green beans, French beans, haricot beans, flageolet, and string beans.
They are all cultivars of Phaseolus vulgaris. Most green beans have a compact or bushy growth habit and are referred to as ‘bush beans’, or sometimes ‘dwarf beans’. Some cultivars have a climbing habit and are known as pole beans.
Runner beans, Phaseolus coccineus, are also climbers. They have striking red flowers which have made them popular as ornamental vines as well as vegetable crops.
Broad beans, Vicia faba, go by many other names like faba beans, fava beans, horse beans, field beans and English beans. It all depends where you live. In Australia, New Zealand and the UK, broad bean is the preferred name whereas in the United States they are called fava beans.
Land has never been more precious.
