Our vibrant, but fragile planet is full of amazing sites - both man-made and natural, ancient and modern - to be explored and discovered.
Sadly, due to a variety of circumstances, many of these sites may not last as long as we hope. We take a look at 10 of these - 5 natural and 5 man-made.
1. The Poles
As global warming becomes ever more apparant, the poles are steadily losing huge amounts of sea ice every year, making it harder and harder for the unique eco systems to survive.
2. The Congo Basin
The Congo Basin is the world's second largest rain forest, with the Amazon obviously taking first place. It is also home to a large variety of rare and exquisite animals like mountain gorillas, okapis and bonobos. Large scale deforestation has not only seen a decrease in life-giving, oxygen producing trees, but has also made it easier for poachers and hunters to gain access to the vulnerable wildlife.
3. Ranthambore in Rajahstan
Although it's quite true that no zoo is complete without a majestic tiger, spotting one in the wild is becoming more and more difficult by the year. From more than 100 000 tigers living in India alone in the early 1900s, their numbers have dropped to below 3200 worldwide. If you have always dreamed of spotting one of these beautiful striped creatures in its natural habitat the Ranthambore nature reserve in India's Rajasthan is your best bet.
4. Madagascar's forests
Due to millenia of isolation on the East Coast of Africa, 80% of Madagascar's fauna and flora is unique to the island. But if nothing is done to protect this living museum, it could all be gone quite soon. The unique forest eco systems are suffering due to logging, subsistance farming and poaching.
5. The Dead Sea
This great mass of water is famous for two things: being the lowest point on earth and, of course, its ability to make humans float like corks on its surface. However, over the past few decades the Dead Sea has been receding by about 3 feet each year due to a large scale siphoning off of water from its neighbours - Israel, Palestine and Jordan.
6. The ruins of the ancient city of Babylon
Although not much of the ancient splendour of Babylon is left, but for a mound of rubble and a gate, these fascinating ruins are in danger of being erased from the face of the planet entirely. This is mainly due to a the almost constant waging of war in this area as well as large-scale developments that are threatening it.
7. Mexico city
When the Spanish conquistadors started finding their feet and settling in the vast untouched world that is Mexico today, they decided to drain a lake and build a European-style city on its muddy remains. Over the years, the buildings started sinking slowly, but surely, proving the idea to be, well, somewhat flawed. Although it makes for a rather quaint visual effect, the booming population is making matters worryingly worse.
8. The pyramids of Giza
Although many modern travellers have shunned Egypt, especially its famed Pyramids and Sphinx, as an almost overly commercialised destination, it may be a good idea to lay eyes on these magnificent structures before they crumble away. Urban sprawl encroaches on their space, air polution eats away at their ancient stone and sewage from nearby slums weakens the plateau on which they stand.
9. The Taj Mahal
Over the top mausoleum or beautiful tribute to love, the Taj Mahal is one of the most beautiful man-made landmarks that draw visitors to India. The ironic part is that by welcoming 2 to 4 million visitors into its gates on an annual basis, this stunning labour of love faces growing damages every year. It has gotten so bad, that strict visitor limitations have been put in place. Best to visit soonest.
10. Little Green Street in London
So, maybe you've never heard of it, but this tiny street on the outskirts of London is one of the very few intact Georgian streets left in the ever-growing metropolis. As a developer aims to use a nearby piece of land, Little Green Street is in danger of becoming nothing more than an easy thoroughfare for them to use.
