This is an interesting excerpt from the
BBC Bloom website about why eating less meat can be hugely beneficial for the environment. And this definitely something we can all do!
Visit
here for the full article and have a play around on the rest of the Bloom website because it's very very enlightening.

A vegan in a 4x4 can do the climate more good than a meat-eater driving a hybrid car. Food for thought?Livestock produce more greenhouse gases than all the world's transport combined, with beef production singled out by a recent UN report as a particular enemy at the gate. Why? Because cattle belch. Methane is a greenhouse gas more than 20 times worse for climate change than CO2 emissions and cattle are full of it. There are 1.5 billion cattle and buffalo worldwide, each producing more greenhouse gas in a day than the average 4x4.
According to the World Health Organisation, the average Briton eats twice the amount of protein they need in a year. By halving the amount of beef you eat, you could save almost as much CO2 as recycling for a year. By going vegan, you can slice off almost as much CO2 in a year as skipping a single return flight to India.
And cows, sheep, pigs and chickens are responsible for more emissions than just their... well, emissions. So, should we be choosing our meats more carefully?
Together, belched methane from cows and sheep, plus methane from manure, account for about 40% of global methane emissions. But that's not the whole story.
Livestock production also plays a big part in deforestation for grazing and cultivating animal feeds such as soya. Deforestation is currently responsible for a staggering quarter of all global man-made CO2 emissions.
Add to that the fact that manure and fertilisers used to grow crops to feed livestock produce two-thirds of global human emissions of nitrous oxide (a gas almost 300 times as damaging to the climate as CO2 ) and you start to see the scale of the problem.
When you crunch those numbers, a single kilo of beef can be responsible for more greenhouse gas than driving for three hours while leaving all the lights on at home, according to 2007 Japanese research published in the journal Animal Science.
Cows can even offer vegetarians something to ruminate on - a veggie who scoffs a lot of dairy products can actually be as bad for the climate as a meat-eater. That's because the dairy industry accounts for about 23% of UK food emissions.
If the UK went the whole hog and stopped eating meat and dairy entirely, without increasing how much we eat of other foods, we would cut our greenhouse gas emissions by 8%. While this may be an unikely scenario, even eating a bit less could lower demand and reduce emissions significantly."
