I recently read two interesting articles about vegan/vegetarianism. The first appeared in the UK’s Guardian, and it regarded scientific projections that the whole world will have to be vegetarian by 2050.
“There will not be enough water available on current croplands to produce food for the expected 9 billion population in 2050 if we follow current trends and changes towards diets common in western nations,” the report by Malik Falkenmark and colleagues at the Stockholm International Water Institute (SIWI) said.
“The report, called Feeding a thirsty world: Challenges and opportunities for a water and food secure world, is being released at the start of the annual world water conference in Stockholm.
There, 2,500 politicians, UN bodies, non-governmental groups and researchers from 120 countries are meeting to address global water supply problems.
The report says dramatic cuts in our meat consumption are the only answer.
‘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,’ it states.”
However, I also recently read a report that bananas are no longer going to be vegan?
“As Science Daily reports, scientists have come up with a new spray they say will prevent bananas from ripening into brown mush for almost two extra weeks. The downside? The spray is made from chitosan, which is derived from the shells of shrimp and crabs.”
The articles are both very interesting and should be read in their entirety but it does raise an interesting issue. Do you think the world is becoming more or less vegan/vegetarian? Put your thoughts in the comments.
