The bad news of food consumption says that climate change is endangering 10 kinds of food.

Original title: the bad news of the food! The study says climate change is endangering ten kinds of food.

The June issue of the Spanish "interesting" issue of Elena Sanz's article "ten endangered foods" said the latest research indicates that if climate change is not controlled again, the common food, such as bananas, avocado, and strawberry, will become less and less, becoming a "luxury" or even lost forever. A study by University of Oxford has pointed out that the lack of vegetables and fruits will push up their prices and change the global diet structure. This change will cause more people to die in the future. Here are some foods that may be on the verge of extinction:

Bananas

The Journal of the public library of science and pathogens in the United States published an article in 2015 that a very aggressive pathogen known as the banana Panama disease tropical 4 (TR4) could make bananas extinct. TR4 directly attacked the banana root of the banana variety that occupies 99% market share today. The lack of diversity in single species or banana varieties is likely to lead to disastrous consequences. Because once TR4 enters banana plantations, banana farmers' only choice is to cut all banana trees and replant them.

Grapevine

Perhaps in 2090, because of climate change, we will no longer be able to drink wine. French researchers point out that grapes are perennial plants and are susceptible to climate change. Over the past 30 years, the vineyards in Europe have been blooming for two weeks, and wine brewing time has advanced by one month. In addition, the composition of the grapes is also changing. The problem is: 40% of the world's vineyards grow only 10 grape varieties, such as New Zealand and China, which are mainly planted in one variety. They do not represent the variety of grapes, are not the best varieties of water absorption, but the most commercialized.

Avocado

Today, avocado is known as the most healthy food containing fat. At present, consumption of avocado has increased three times, and this demand is too large for tropical crops that need a lot of moisture. In the major avocado producing countries, Mexico and Chile, avocado planting has replaced pine trees, which increases carbon dioxide emissions, accelerates climate change and water exhaustion. We should develop more drought resistant avocado varieties as early as possible.

Strawberry

Nowadays, strawberries are widely planted all over the world. But Spanish researchers have found that rising temperatures can increase strawberry early results, reduce harvest and prolong the planting cycle.

Coffee

London researchers point out that the wild forests that contribute 70% of the global coffee production in the world are facing extinction and are likely to be difficult to find in 2080. The Arabica coffee tree, which has been planted, is suffering from disease and its production is declining. Without the wild Arabica coffee tree to provide improved genes, climate change and new diseases will destroy coffee plantations.

Oysters and mussels

Carbon emissions exacerbate ocean acidification and damage certain marine organisms, especially shellfish. It is estimated that the calcification rate of oysters and mussels will be reduced by 10% and 25% respectively, causing some individuals to be unable to grow up and even more vulnerable to natural enemies even if they grow up. The future of the bivalve shellfish is worrying.

Wheat

Wheat is the most important grain in the world, but its future is uncertain. Studies have pointed out that when the earth temperature rises once, the wheat output will decrease by 6%. This research is based on the output prediction data of 30 planting models and international agencies, and is reliable and credible.

Potato

Global warming threatens potatoes to face new diseases. It is predicted that potato production will be reduced by 26% by 2085, and this is a very large reduction for the crop, which is second only to wheat and rice. However, researchers believe that more than one thousand varieties of potatoes, adaptable, should be able to better adapt to the new environment than other crops.

Cocoa

If environmental trends do not change, chocolate will soon become a luxury. Cocoa trees producing chocolate raw materials only grow in the area between 20 degrees north and south, requiring stable temperatures, humid climate, abundant rainfall and soil rich in nitrogen. In general, the tropical regions of Cote d'Ivoire and Garner are more suitable. But the study thinks that the temperature will rise 2.1 degrees in 2050, which will reduce the planting area of cocoa tree. So cocoa farmers are picking seeds that are more resistant to drought. Another way is to genetically modify the cocoa tree to adapt to climate change.

Other fruits that are in danger

Global warming and drought will reduce the planting area of peach, apricot, plum and other fruit trees in California to 10% in 2050. In Australia, like Europe, there will be fewer apples in 15 years, because the winter climate is no longer suitable for apple trees to survive. More seriously, the number of bees pollinated by fruit pollinators is decreasing due to climate change.
