Our long-standing relationship with plants

Plants do not just act as potential air purifiers.  They also represent part of the original ecosystem in which mankind evolved.  Plant species as we know them today have been around for some 150 million years.

Human evolution only started 4 .5 million years ago, and produced homo sapiens - modern man - about 100,000 years ago.  Our entire evolutionary history was therefore closely linked to nature.

It is interesting to note that there have been only very minor changes in mankind's biology, physiology or genetics over the past 10,000 years.  We are virtually identical to the people who lived at the end of the ice age, when the ice sheet covered large parts of northern Europe.  On the other hand, our living and working environments have altered considerably, particularly in more recent times.

No wonder plants are so important to us and have such a good effect on our well-being generally.
