As America counts the cost of the BP oil spill, Britain recovers from record-breaking heat, ice caps melt under the polar bears' paws, floods wash away the homes of millions and we wonder where all the bees have gone, Rex Features showcases its rich library of environment-themed photography.

From the ravages of climate change and global warming to the tragic results of industrial pollution, and from the mass agriculture and factory farming needed to feed the world to the man-made solutions to these man-made problems, Rex presents a selection of images to illustrate one of the most important topics in the world today.
