In pictures: Your changing world (BBC News)

Environmental change is happening on our doorsteps. We asked BBC News website readers to send us images of how these changes are affecting their lives.

Oliver Clissold from South Africa sent this picture of Table Mountain:
"How the Cape Flats have changed over the last hundred years. Cape Town is still one of the most beautiful places on Earth, but this early morning look shows the smog and concrete that have reformed the landscape of this Eden.

Garden or lake? Leslie Wyn Evans, Canada:
"While there are so many places in the world that qualify for this category, it is surprising how much change has occured in places that never had problems in the past.
"This is a picture of our back lawn in winter.
"As you can see, we now have enough water to qualify as a lake in winter - although it is lawn in summer.
"The good part is that the water table ensures that we always have green grass."

New Zealand Ilan Kelman, UK:
"This picture is of the parched hills just south of Christchurch, New Zealand, during the summer heat wave and drought of 2003-2004."
Europe also suffered a major heat wave in 2003, with temperatures soaring to unprecedented heights in some places.
According to climate scientists, heat waves in the 21st Century will become more frequent, more intense and longer lasting.
