Global warming  is reflected in food scarcity and rising prices. Recent
 research from a team of US scientists studying rice yields across six 
major rice exporting regions  in Asia found that rising night-time 
temperatures have caused rice production to decline by 10 to 20% over 
the past 25 years. This temperature effect has overshadowed improvements
 in growing techniques that would otherwise lead to higher yields. 
In
 a related Philippine study, rice yields were found to drop by 10% for 
every 1 degree Celsius rise in night-time temperature. More recently, 
farmers in some parts of India are facing too much water due to 
flooding, while others are experiencing droughts, and many have not 
planted even half of what would normally  be needed out of fear that 
there will not be enough water to grow the rice.  
Mohammed Ansari, Farmer (in Hindi):
 Even if it starts to rain now, we will not get any crop. There is a 
deadline for the rice to start growing – that is till the middle of 
August. And that time has now passed. So we will not have any crop this 
year.
Jugari Paswan, Indian labourer (e): We are poor people and are desperate for food to eat. Our children go to sleep hungry. What can we do? 
Rita, Indian villager (F):My hungry child cries all the time, there is no food to feed him. How can we survive like this?
And
 this summer’s extreme weather in Russia as well as Ukraine, which has 
been attributed to climate change, has led the governments to decrease 
forecasted wheat yields and place a ban on exports. 
This in turn
 has even affected other grains such as barley, which has doubled in 
price in the last six weeks due to a combination of lower wheat yields 
in Russia and reduced barley yields in Europe and Canada due to 
unfavorable weather. 
With prolonged drought and hunger being 
endured by millions in countries such as Africa, the scientists warn 
that these declines are just some of the indications of an emerging 
global food crisis as extreme conditions continue due to unchecked 
climate change.
We thank the scientists for these factual 
insights into the current and ongoing threats to food security due to 
global warming.  Let us all quickly shift to lifestyles that complement 
the balance of nature for the sustenance and survival of all people on 
the planet. 
Speaking with concern for the welfare of people 
across the globe, Supreme Master Ching Hai addressed the matter of food 
shortages as well as the most efficient solution during an April 2009 
videoconference in South Korea.
Supreme Master Ching Hai:
 All this is important because if humans are in shortage of food or of 
water, then conflicts, of course, will break out. When our family 
members are in danger of hunger or thirst, maybe we would do anything to
 bring food to them. 
So reluctantly, some virtuous or good 
people might even go astray and cause conflict between neighbors and 
then, on a larger scale, it will cause conflict between nations. 
Scientists
 have documented that one serving of beef takes more than a thousand 
gallons of water to produce. By contrast, the vegan diet uses about 
one-tenth of that amount. 
So, the best way to prepare for 
conflict is to take complete prevention.  The vegan diet will help us to
 achieve that goal, and almost immediately.
