THE MOST ESSENTIAL ELEMENT for all life, the only chemical equation I can actually recite: H20.

In Tanzania's Selous National Park, the river level falls, creating horse shoe bends and lakes where birds and animals gather.

A fishing boat rests on the beach at Bagamoyo, Tanzania. Bagamoyo was a major transit point for the slave trade.

Nhakotakota was not the greatest park for wildlife, although we did catch the scent of elephants while hiking. Plenty of monkeys and birds came to the camp HQ, not far from this part of the river.

Elephants are commonly seen at the water in Vwaza Marsh National Park, Malawi. As well as gazelle and hippos, leopards roam, but are rarely seen.

Kenya's Amboseli National Park's wetland supports an incredible number of elephants, as well as hippos, flamingos and other birds.

Two nights at this lovely Kapishya Hot Springs refreshed us no end, even after the previous day's 8 hour walk. Loved the food too. Zambia.

Pammukale, Turkey. Thermal rich waters of the travertine terraces have been famous since Roman times.

The Tigris River, Hasankeyf. Sadly, the famous river has been damned, for power, displacing the city's people, and drowning 400 years of history.

Anzac Cove in Gelibolu (or Gallipoli to the west) where thousands of Australian< New Zealand, British, and Indian troops stormed ashore in World War One.

When the rain falls, 550 million litres a minute flow over Victoria Falls. Man made climate change has caused many years of drought and flows like these may never return.

A massive volcanic explosion blew away most of the island which is Santorini, blessing us with these caldera views.

Indonesia recently launched plans to open many "Balis". The country ahs no shortage of island and beaches, like this one on Alor, which is close to Timor.

The colours and clarity of Lake Tanganyika are a sight to behold. The lake is an incredible source of fish for both food and aquariums.

Flooding is part of life in Vietnam's Mekong Delta, but was particularly bad when I was touring around there in 1994/5.
