Although i don’t support encroaching on our parks, these wildlife corridors do allow seemless movement of animals especially elephants that follow same migratory routes for decades.

A resort in Zambia knows this too well. They built it right in the middle of a corridor between elephant sanctuary and bush full of wild mangoes,so every year when mangoes a ripe ,the beasts cut right through the lobby[SIZE=1] i know this was posted years ago but you get the point

Man should not interfere with nature

The pillars raising the railway ensure that development coexists with nature.

What about the noise, pollution, etc?

Quote:

Nairobi is one of the world’s fastest growing cities. It is also unique in encompassing, within its precincts, a major national park that supports lions, rhinos, and other large wild animals. Despite its modest size, the biological diversity of Nairobi National Park is greater than that of some entire countries. It is also a sanctuary of global significance for some endangered species, notably the black rhinoceros.

These wonders lie within easy reach of millions of Nairobi residents, as well as tourists and business visitors from all over the world. The co-existence, side by side, of bustling metropolis and natural wildlife paradise sets Nairobi apart from every other capital city on earth.

The proposal to construct a railway through the park has led to a major conflict between conservation and development interests, and a heightened level of public concern about environmental compliance in the implementation of large-scale development projects. It has also divided the conservation community in Kenya.

Most Kenyan conservationists are resolutely opposed to the proposal. However, one our most famous and respected colleagues, Richard Leakey, has been at the forefront in supporting the proposed project. In my many conversations with him, it is clear that he is convinced that, like it or not, Kenya will continue to develop and therefore change is inevitable, especially in one of Africa’s fastest growing cities.

He thinks that the only way to save the park is to raise the railway on pillars like a viaduct 18 m above the park. He is convinced that this will not harm the wildlife, but may in fact become recognized as a wonder of technology, like the Forth Railway Bridge in Scotland, Cikurutug Bridge in Indonesia which soars above a rainforest, and the Landwasser Viaduct in Switzerland to name a few.

Richard Leakey believes Africa should not be afraid to aspire to greatness in construction, but most of all, he is so confident that it will work in Nairobi Park that he believes it will be a model for other African countries facing similar challenges, such as the Tanzanian plan to put a road across the Serengeti.

The Government of Kenya’s argument in favour of the route through the park is more straightforward: it is the cheapest and, technically, the easiest option available. But most conservationists in Kenya, and many people around the world, would say that it is madness to take a decision like this based purely on economic and technical criteria.

What about the noise and pollution of tourist cars driving in the park 7 days a week? The train on the raised tracks has less environmental impact.
