title="";
body="The three main greenhouse gases (GHG’s) are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).  Methane has 21 times the “global warming potential” of carbon dioxide, and nitrous oxide has 310 times the “global warming potential” of carbon dioxide.";
}

if (quotes==1) {
title="";
body="Soil management and cropping practices contribute emissions of N2O (due to fertilizer application methods). These sources accounted for about 29,900,000 tonnes of CO2e or about 51% of total Canadian GHG emissions from the Agriculture Sector in 2002. However, with increased adoption of no-till and reduction in frequency of summer-fallow, agricultural soils removed 0.5 Mt (500,000 tonnes CO2e) from the atmosphere. ";
}

if (quotes==2) {
title="";
body="1 Mt means 1 Megatonne, which is equal to 1,000,000 tonnes of CO2 equivalent (CO2e).";
}

if (quotes==3) {
title="";
body="In 2002, agriculture was responsible for about 8.1 % (or about 58,700,000 tonnes) of the total GHG emissions in Canada (728,000,000 tonnes).  This was primarily in the form of methane and nitrous oxide.";
}

if (quotes==4) {
title="";
body="In 2002, rumen fermentation by “non-dairy” ruminant animals in Canada accounted for 13,600,000 tonnes of CO2 equivalent emissions in the form of methane.  In comparison, 24,000,000 tonnes of CO2 equivalent are emitted from Canadian landfills each year, mostly in the form of methane.";
}

if (quotes==5) {
title="";
body="About 98% of the GHG emissions from a cow come out the front end through breathing and eructation.";
}

if (quotes==6) {
title="";
body="The volume of 1 Tonne (1000 kg) of CO2 gas would fill a two-storey, three bedroom house…(That’s about the volume of  a room which is 27 feet wide by 27 feet long by 27 feet high.)";
}

if (quotes==7) {
title="";
body="One feedlot steer emits about 47 kg of methane/year from enteric fermentation.  Methane has a global warming potential of 21 times that of C02, therefore this 47 kg of methane equates to 47 x 21  = 987 kg of C02e (C02 'equivalent') per year, or just about 1 tonne/hd/year.";
}

if (quotes==8) {
title="";
body="One  beef cow emits about 72 kg of methane/year from enteric fermentation.  Conversion of this amount of methane to C02e is 72 kg x 21 = 1,512 kg/hd/year C02e or about 1.5 tonnes/hd/year, or about 1.5 'houses'.";
}

if (quotes==9) {
title="";
body="Burning about 416 litres of gas in a vehicle produces 1 tonne of CO2.";
}

if (quotes==10) {
title="";
body="Driving a sport utility vehicle  20,000 kilometres/year emits about 6 tonnes of CO2e…i.e. fills about 6 of the above 'houses'.";
}

if (quotes==11) {
title="";
body="The digestibility of feed is the biggest determinant of the amount of methane emitted from the rumen of beef cattle.  The more highly digestible the feed, the less methane emitted per pound of feed eaten.  ";
}

if (quotes==12) {
title="";
body="Reducing the confined winter feeding period by extending the grazing season (by swath grazing or grass stock piling for example) can reduce the potential greenhouse gas emissions associated with manure build up, as well as reduce the fossil fuel costs and GHG emissions from hauling and spreading manure.";
}
if (quotes==13) {
title="";
body="Soils beneath healthy perennial forage and pasture stands can store significant amounts of carbon.  Increasing the organic matter of pasture soils by range planning and adopting good grazing management also improves pasture productivity.";
}
if (quotes==14) {
title="";
body="Incorporating a legume into pasture and forage stands can improve forage digestibility and productivity, thus reducing GHG emissions by grazing cattle.  The nitrogen fixing capabilities of legumes can reduce the need and expense for applying nitrogen fertilizer, and reduce the greenhouse gas emissions associated with fertilizer production.";
}
if (quotes==15) {
title="";
body="Healthy riparian areas can “sequester” or store significant amounts of soil carbon.";
}

if (quotes==16) {
title="";
body="Shelterbelt trees can remove significant amounts of carbon dioxide from the atmosphere and store it as carbon in the wood and roots over the years.";
}

if (quotes==17) {
title="";
body="Adding edible oilseeds such as sunflower or canola to feed rations can alter the rumen environment and reduce methane emissions by cattle by 10-24%.";
