Letter: Humans put planet at the greatest risk

For over a billion years this planet was occupied by only single celled creatures. They lived in the sea. The land was barren and volcanic.

Then these single celled creatures discovered how to photosynthesize. This gave them the ability to grow multicellular creatures such as the sponge. They eventually evolved into all kinds of sea dwelling creatures. The trilobites were the most successful, they colonised every niche.

This period was called the Cambrian period; it lasted approximately 500 million years. The first to colonise the barren and volcanic land were the plant life. They covered it with forests. They put 35 per cent oxygen into the atmosphere. Eventually the sea dwelling creatures evolved lungs and followed the plants onto the land. They have evolved into various forms of life including us humans. All kinds of life have been on the land for over 500 million years.

The dinosaurs were here for over 150 million years. The forests receded then there was only 21 per cent oxygen in the air. Then after millions of years the human being evolved. We are now cutting down and clearing the forests. The very things that put the oxygen into the air.

Humans cannot live without oxygen. We have only been, here for two million years. Have we decided to commit suicide?

We must be the most stupid animal that has ever lived on this planet.
