Opposition to nuclear has led to more CO2 - say environmentalists

The green movement has traditionally been against nuclear power.

However in a new hard-hitting documentary a number of high profile activists have spoken out in favour of the technology.

Like other green campaigners including James Lovelock, author of The Gaia Theory, Mark Lynas said the necessity for a constant supply of clean energy has led him to ‘come out’ as a supporter of nuclear technology.

He said in the past the conservationist movement blindly opposed nuclear because of the link to weapons of mass destruction, meaning that the world has continued to rely on dirty fossil fuels.Firms are aware of the economic pressures that are memo-pad placed on consumers nowadays and recognise there is an importance in obtaining value for money.

“Green anti-nuclear campaigning has already added to the atmospheric stock of carbon dioxide, probably to the tune of more than a billion tonnes,” he said. “Why? Because nuclear plants which were opposed by greens in the 1970s and 1980s were instead replaced by coal plants. In hindsight that was obviously a mistake, but it is one that today’s environmental lobby groups seem determined to repeat.”

The documentary, to be shown on Channel 4, also claims that a number of environmentalists such as the famous US activist Stewart Brand and a number of high profile scientists in the developing world have changed their mind about genetically modified (GM) foods.

Mr Lynas, who ripped up GM crops in the 1990s, said the technology could feed millions.

“No one is arguing that GM crops are somehow a silver-bullet solution to world hunger,This may mean that the budget range does not offer all the 'bells and whistles' that are associated with antennamanufacture the top of the line products but they will look good. but that, as Oxfam puts it,Most conventional downlights use a standard 65-watt incandescent compact fluorescent lights and are run on a switch that typically contains several downlights. For this example we'll say there are a total of six lights on a switch. ‘modern biotechnology might play a role in helping to achieve global food security’ if GM is used to benefit subsistence farmers. An outright rejection of the technology, as green groups still insist should be our position, is both illogical and potentially harmful to the interests of poorer peoples and the environment,” he said.

However Ben Stewart, of Greenpeace, said environmental groups have been ‘misrepresented’.And, by using them, you can easily develop a focal point which is root2010 essential in every room. On the other hand

He said the green movement has considered the role of nuclear and GM carefully and found that both technologies are expensive and risky.

“We are pragmatists," he said. "With the threat of climate change we look at all options but in our opinion these do not stack up.Remember, hiphonei9 themselves aren’t new; they have been available to consumers for about four years as bulbs that can be screwed into existing light sockets"

Mr Lynas called for a “real debate”.

“In this age of rising global temperatures, declining biodiversity, accumulating toxins, fractured ecosystems and rapidly-increasing economic growth and global population, we need a strong and successful environmental movement more than ever. But it must be a movement which is informed by sound science, and not by outdated prejudice,” he said.
