Farming vegetables causes less greenhouse than livestock production. Climate experts say people should eat more vegetables for better health and for slowing greenhouse gas emissions that cause climate change.

Consider that studies show farming and other land use account for about a fourth of all greenhouse gas emissions, and about half of methane gas emissions are released into the atmosphere from cattle and rice fields. Meat in particular has more greenhouse gas emissions. 

Climate experts say the nutritional value of wheat grown in higher CO2 areas is 6% to 13% less for protein, and 5% to 8% less for iron. Another problem aggravating the situation is that drought has grown 1% a year between 1961 and 2013, IPCC researchers have found. This is a result of the growing climate change issues. Drought and nutrition is a major problem in India and Africa.

How ethanol picture as a useful alternative fuel has changed completely in the past year. The economics of ethanol also have changed completedly in the past year, as corn prices have risen to above $3 abushel and stayed there, even with the biggest corn crop since 1945, and prices of ethanol have dropped with huge oversupply of ethanol from $5 a gallon in June 2006 to about $1.85 a gallon today. Global ethanol production has grown from 10.9 billion gallons in 2006 to 13.4 billion gallons in 2007 according to IEA. US's ethanol production is about half of this or 7 billion gallons and is up 80% in 2 years. The production capacity of ethanol with new plants is expected to jump to about 12 billion gallons in 2008 even as demand for ethanol is about 7 billion gallons.This huge oversupply accounts for the drop in prices of ethanol with margins dropping from $2.30 in 2006 to 25 cents in late 2007. Its become less and less attractive as an alternative fuel as more studies appear and more groups cite the different ways in which ethanol has destructive effects on the environment. Corn is in demand by food companies and by livestock companies in the USA and generally across the developing world so raising corn prices is seen very unfavorably around the world. Nation Academy of Sciences study and a National Research Council study says corn based ethanol could strain water supplies and impair water quality. American Lung Assocation worries about the the air pollution from burning ethanol in gasoline. And a EPA Spring 2007 report says ozone levels increase with increased use of ethanol. A study coauthored by Nobel prize winning chemist Paul Crutzen says it might exacerbate climate change because of the added fertilizer used to produce corn raised emissions of nitrous oxide. All this has made people wary of ethanol and much of the early enthusiasm for ethanol has vanished. The lobbying struggle pits the ethanol producers and the farm lobby in the midwest against oil companies which don't like being forced to use a non-petroleum fuel even with a subsidy of 54 cents of gallon for blending ethanol into gasoline, and food and livestock companies which need corn at lower prices. Add to this the weight of environmental organizations and countries across the developing world which simply don't like the idea of using scarce food resources in this manner and find this to be just not a right thing to do for the world's poor which need corn as a basic food source. Consider Mexico where this affects the price of a staple food corn tortillas and China which bans the use of corn for making biofuels, both countries seek to keep food prices low for the country's large numbers of rural and urban poor people and could see the stability of these countries disturbed by huge rise in food or fuel prices. As a result of all this the ethanol lobby is looking to Congress to mandate a certain usage figure of ethanol in gasoline production in the new energy law. This legislation now could become controversial in the future as better ways of solving the energy crisis such as automobile fuel efficiency reducing demand and conservation, as well as other alternative sources that have fewer adverse environmental impact come into play. ...

Impossible and Beyond Meat, two new companies promoting plant based meat are popularizing the sale of plant based products that contribute to efforts against climate change and at the same time improve health outcomes. Growth of animal based meat consumption is now less than 1% compared to 14% for plant based meat.  New technology is helping improve plant based products using new engineering and production techniques to form plant fibers and proteins that mimic what consumers are used to.  The growth is bringing new companies into the market, including Nestle, Smithfield and Cargill. On the retail side Starbucks, Yum Brands KFC, and McDonalds, Burger King are adding plant based burgers to their product mix.  A new development is cost with the new manufacturing technologies leading to lower costs that compete better on price with animal meat products. Impossible based in Redwood City, California, has a 15% price cut to reduce what it charges to $7.90 to $8.50 a pound.  Impossible and Beyond Meat say they use less energy, water and grain to make burgers from soy and pea protein, than companies that feed, slaughter and transport livestock. Plant based production processes are only now reaching the kind of scale needed to compete with sales of $1 billion in plant based meat. The effects on climate change are not fully understood by people, as animal based products have a much larger footprint on the climate. In particular the health benefits are not understood fully. Animal based fat including from dairy increased chances of prostate cancer say experts. The health benefits of soy protein compared to animal protein are also being better understood in relation to cancer and heart disease. Combining plant based protein with fruits, nuts, beans, ancient grains and vegetables, and reducing meat in the diet,  is now considered a healthy alternative that also is healthy for the environment.   ...
