The degradation of the environment has consistently grabbed the headlines in the past few years as the way in which the world is arranged threatens the very existence of life on this planet. Mick Brooks, editor of the Socialist Appeal, talks at the Socialist Appeal day school in December on capitalisms contibution to the environmental problems we face today and and what alternative a socialist society can offer.

Earlier this year we received a letter from a reader of Socialist Appeal who says we put too much importance on one factor that contributes to climate change, human-induced emissions of “greenhouse” gases. In his answer Phil Mitchinson looks at the broader aspects of pollution, climate change and so on and stresses the need for a radical, socialist transformation of society if we are even to begin to tackle these vital problems.

Despite the almost incessant rainfall Britain is officially in a drought. There can be no doubt that climate change is contributing to changing weather patterns to adversely affect our water supply. This is a foretaste of what conditions will be like here in the not too distant future if something is not done to halt and reverse the destruction of our environment on a global scale.

The debate over global warming and the consequences it may or may not have for planet Earth and humanity has been raging for several decades now. Global warming is an endless source of controversy, but one thing is clear – our climate is changing.

In this essay Engels explains that the decisive step in the evolution of humans was the adoption of an upright posture. This move from walking on four feet to two was the result of changes in the environment, which forced some primates from the forests to the ground below, where they were required to travel long distances in the search for scarce food resources. This transition to a bipedal, upright stance freed up the hands and allowed them to develop a range of flexible functions.
