He is amazed at how many junk he has found. At 17,000 feet he was coming across cornflakes packets, several of empty caviar cans, and hundreds of the hypodermic needles and syringes. So far he has been collecting enough trash to cover three football fields.

For the last six months David has prepared to climb to the summit of Everest. He is training hard in the Himalayas and has been being on a strict diet. If he succeeds, he will be the youngest British person ever to reach a top of Everest.
