Today in this present century,we are facing many environmental problems.Among ma them we can see scarcity of water eading water scientists have issued one of the sternest warning yet about global food supplies,saying that the worlds population have to switch almost completely to a vegetarian diet over the next 40years to avoid catastrophic shortages.
Humans derive about 20% of their protein from animal-based product now, but this may need to drop to just 5% to feed the extra 2 billion people expected to be alive by 2050,according to research by some of the worlds leading water scientists.
There will be no enough water available no current croplands to produce food for the expected nine billion population in 2050 if we follow current trends and changes towards diets common in western nations,the report by Malik Falken mark and colleagues at the Stockholm international water institute (SIWI)said.
There will be just enough water if the proportion of animal-based foods is limited to 5% of total calories and considerable regional water deficits can be met by a .... reliable system of food trade.
Dire warnings of water scarcity limiting food production come as Oxfam and the UN prepare for the possible second global food crisis in five years.Prices for staples such as corn and wheat have risen nearly 50% on international markets since june, triggered by severe droughts in the US and Russia,and weak monsoon rain in Asia.
