Environmental scientists believe that a warming climate will cause ten foods to disappear
Time, October 15, 2018: President trump on CBS '" 60 minutes "Sunday night retracted his earlier claim that" climate change is a hoax, "adding that he did not know it was man-made and that the global climate would" change back." On June 1, 2017, trump had announced that the United States was pulling out of the Paris climate agreement. According to the weather website, a new study warns that the following 10 foods could be endangered if climate change is not controlled.
1. The banana
Banana Panamanian tropical type 4 (TR4) is a direct attack on the roots of the banana plant, which accounts for 99 per cent of the market, and the lack of diversity in the monoculture and banana varieties is likely to be disastrous. Because once TR4 enters the garden, the only option for the banana farmer is to cut down all the banana trees.
2. The grapes
Because of climate change, there's a good chance we won't be able to drink wine. French researchers point out that grapes are perennial plants that are vulnerable to climate change. Over the past 30 years, the flowering of European vineyards has been brought forward by two weeks, wine has been made a month earlier and the composition of the grapes has changed.
3. The avocado
Avocados are considered one of the best sources of healthy fat. At present, in Mexico and Chile, the main producing countries of avocados, excessive demand has led to large areas of pine forests being replaced by avocados, not only increasing carbon dioxide emissions, but also accelerating climate change and water depletion. As for avocados, which need a lot of water, we should develop drought-resistant varieties as soon as possible while controlling their growth.
4. The strawberry
Spain is the second-largest fruit producer after the United States, with a wide range of strawberries. But the researchers found that higher temperatures were associated with shorter fruit seasons and a greater likelihood of lower harvests.
Wild forests of arabica coffee, which now account for 70 per cent of global coffee production, are facing extinction and could be hard to find by 2080, with plants and animals in these regions also becoming the most threatened species on earth, according to researchers in London. Today's arabica plants are also suffering from disease and declining yields. If improved genes are not available for wild arabica plants, minor climate change and new diseases will kill them.
6.Oysters and mussels
When carbon dioxide in the atmosphere is absorbed by seawater, it will cause ocean acidification, resulting in the increase of acidic seawater with low hydrogen ion concentration index (pH), which will damage some Marine organisms, especially shellfish.
7. The wheat
Wheat is the world's most important food, but its future is uncertain. , according to a study the earth's temperature rise every 1 ℃, wheat yield will be reduced by 6%.
Global warming is putting potatoes at risk from new diseases.
If environmental trends do not change, chocolate will soon become a luxury. Cacao trees, which make chocolate, grow only in regions between latitude 20 degrees south and north, requiring stable temperatures, humid climates, abundant rainfall and nitrogen rich soils.
10. Other fruits
Global warming and drought will reduce the planting area of fruit trees like peaches, apricots and plums in California by 10 percent by 2050. In Australia, as in Europe, there will be almost no apples after 15 years because the winter climate is no longer suitable for apple trees. More seriously, the number of bees, the main pollinators of fruit trees, is declining due to climate change.
The study suggests five possible factors: increased greenhouse gas emissions, depletion of ozone in the Antarctic stratosphere, aerosols from volcanic eruptions, smoke and ozone pollution in the troposphere, and natural changes such as el nino and la Nina. The study says warming could affect billions of people and affect food and species populations in those areas.
At present, it is urgent to "do a good job on the relationship between soil and fertilizer and tackle climate change".
