Back in the 1960s and 70s, the world was becoming more aware of the destructive effects of industry on the environment and people were starting to think seriously about ways of protecting the environment. One man who was particularly affected by this subject was Gerard Morgan-Grenville. As Morgan-Grenville travelled round earning his leaving as a gardener, he noticed signs of the damage that was being done to the countryside around him. It wasn’t long before Morgan-Grenville decided that he had to do something about this situation. He felt that if people could be shown a better way of living then maybe they would be interested enough to try to protect their precious environment. 2. Mr. Morgan-Grenville decided to set up a project that would prove what was happening to our surroundings and what could be done about it. So, in 1975, Morgan-Grenville created the Center for Alternative Technology (CAT) in a village in Wales. 3. The main aim of CAT is to search for an ecologically better way of living by using technology that does not harm the environment. One of the most important things CAT did initially was to explore and demonstrate a wide range of techniques and to point out which ones had the least destructive results on the world around us. It is also very important for CAT to provide information and advice to people all over the world. If more and more individuals are informed about how much damage our modern lifestyle is doing to the planet, maybe more of them would be prepared to look for solution.-
