Eco-terrorism is an act of violence committed in support of environmental causes, against people or property.The United States Federal Bureau of Investigation (FBI) defines eco-terrorism as "...the use or threatened use of violence of a criminal nature against the people guilty of destroying the environment or their property by an environmentally-oriented, subnational group for environmental-political reasons, or aimed at an audience beyond the target, often of a symbolic nature." The FBI credited eco-terrorists with US$200 million in property damage between 2003 and 2008. A majority of states in the US have introduced laws aimed at penalizing eco-terrorism.Eco-terrorism is a form of radical environmentalism that arose out of the same school of thought that brought about deep ecology, ecofeminism, social ecology, and bioregionalism.

    Vaillant Eco Tec Pro 28

    I was going to attempt to install a Tado thermostat in to an Ecotec Pro 28 but as soon as I opened the front cover a black air flow dropped out of it. I’m assuming this should be secured in to place? Also the black heat protection on the front cover is disintegrating. The boiler had its...

    VAILLANT ECO TEC PLUS 835

    Installed the above boiler today. They quote 14 ltrs per min hot water. Looking at the heat exchanger, it does not look any different in size to the 832 (well I know, its only 3kw more!), but comparing this to the 838, that heat exchanger is nearly double the size? and the flow rate on that is...
