I HAVE been an avid watcher of “Seven Worlds, One Planet” on BBC television, which was narrated by Sir David Attenborough.

All seven continents were featured with lots of tooth and claw footage and they left Africa until the last. I don’t think I have ever been so moved by a TV programme.

I am sure Sir David must have had a lump in his throat seeing huge piles of elephant tusks, the product of poaching and it is predicted that wild elephants will be extinct by 2040 – that is only in 20 years time.

It reminded me of the massive house-size piles of buffalo skulls in the USA in the 1800s – millions of dead buffalo, lots killed for sport.

I have always worried about Africa as they seem to equate animals equal money.

They have some of the biggest animal herds ever seen on earth but so did the USA and Canada and the buffalo were nearly wiped out by man and guns.

The destruction of forests in Africa is also a major problem.

When will we ever learn?
