1, The demilitarised zone (DMZ) separating South and North Korea is home to over 1,000 plant species and rare animals. The DMZ Forum is a lobby group promoting the idea of turning the area into a nature reserve.

2. The forest is the world's biggest after the Amazon. Now Britain and Norway have created a £108m fund to help protect it from logging and reduce carbon dioxide emissions.

The Congo basin forest is home to around 50 million people in six countries including Cameroon, Central Africa Republic, Democratic Republic of the Congo, Equatorial Guinea, Gabon, and Congo-Brazzaville.

The Congo basin forest is twice the size of France and exceeded in size only by the Amazon. It is estimated that logging - much of it illegal - destroys an area the size of 25,000 football pitches every week.

The UN estimates that at present rates two-thirds of the forest will have vanished by the year 2040.

Another great clip.
