With the climate change, maybe there will be no coffee in the future, there are no red wine in the party, and even corn and honey will become luxury goods?Intersection

The melting of the north and south poles, the hot summer, the frequent floods, the extreme drought, the wildfire ...

The threat of climate change has gradually gone to people's daily life from where we can't see it.

And these are just the beginning.

It is coming to our table to affect the flavor and choice of food.

With the intensification of climate change, it may become more and more difficult to drink high -quality coffee.

A summary study of the University of Tofz in the United States believes that the quality of coffee is vulnerable to changes in environmental factors related to climate change, such as altitude and light.

In addition, coffee production and production areas will change with climate change.

A study published in The Public Library of Science-One published in February 2022 predicts that due to the rise in temperature, the land suitable for coffee planting will be reduced by 50%in 2050. At present , Indonesia, Colombia) The area for coffee planting will also be significantly reduced.

A study published in the Science Advances journal in 2019 also found that 60%of wild coffee species are endangered and threatened the sustainable development of global coffee production.

Global warming will also threaten the supply of wine.

Grapes are very sensitive to climate change. In 2019, a study published in the PNAS journal is expected:

If the global warming is 2 ° C, the grape area suitable for planting in the world will be reduced by 56%;

If the global warming is 4 ° C, then 85%of the appropriate planting areas will not be able to provide grape production for wine production.

With global warming, the grape varieties planted in the existing wine production areas may need to be adjusted according to the trend of climate change.

Taking the Burgundy area of ​​France as an example, if the global warming is 2 ° C, the three common red grape varieties such as Pinotuo, Cabernet Sauvignon, and Merlot may be replaced by other grape varieties.

The precocious varieties, such as Pinotuo, are particularly sensitive to the temperature and seasonal changes brought by climate change.

Some precocious varieties, such as Hei Pino and Sasla, may move to the northern area to plant.

This summer, about 7.8 billion bees in South Korea disappeared collectively.

In Kyrgyzstan, which is rich in honey, its annual output of honey has decreased from more than 10,000 tons in the 1990s to more than 3,000 tons today, because the drought in Central Asia has destroyed the wild flowers of the alpine ranch.

The bee farmers had to transfer the beehive to a higher altitude and find enough wild flowers for their bees.

Meteorological expert analysis, for artificial breeding bees, its growth and development are extremely sensitive to factors such as environmental temperature, humidity, lighting, and wind.

The first is the temperature. The most suitable living temperature of bees is 15 ° C to 25 ° C. The temperature is lower than this interval, and the bee will gradually become frozen; the temperature is higher than 40 ° C, and the bee will stop picking honey.

Then there is humidity, the air is too large, the nectar is not easy to concentrate, and the bees cannot fly because the wings are too humid; the air humidity is too small, which will seriously affect the growth and development of eggs, larvae and pupae.

In addition, the weather with good light, windless or breeze is most suitable for bees flying. If the wind is too large, it will also affect bees flying.

In addition to artificial breeding bees, wild bees are also threatened by climate change.

A study published in the Global Change Biology journal found in 2021 found that the warm winter and long and hot summer will occur more frequently, which will constitute a serious challenge to the wild bee population.

As the bees "disappear", the influence is not just the output of honey. As the key passenger of agricultural and natural ecosystems, the seemingly inconspicuous bee also affects the survival of more plants and crops, threatening the threat. Global food security.

If the temperature continues to rise, the maple syrup on the muffin will also disappear.

Because the increasingly warm and dry climate makes it difficult for sugar maple trees to make maple syrup.

A report published in Journal of Ecology in 2018 shows that if the temperature of the earth rises more than 5 ° C and the summer rainfall decreases by 40%, the growth of the sugar maple tree will stop until disappear.

A study published in Journal of Ecology in 2020 also pointed out that in the face of climate change, sugar maple trees did not continue to move north, because the soil characteristics of the north areas are not suitable for the survival of sugar maple trees.

Rice is a staple food for more than half of the world's population. It is related to the safety of 3.5 billion people, and climate change is more influential for rice.

On a positive side, global warming can extend the production season of rice in northern my country and reduce the freezing damage in winter.

However, the disaster weather accompanied by climate change may also offset the positive benefits of warming and make the rice generally reduce the production.

Climate change also affects the yield of corn.

In November 2021, the research published by NASA in Nature Magazine is expected to:

If greenhouse gas emissions are not reduced, climate change may affect the production of corn in 2030, and the output of global corn is expected to decrease by 24%.The increase in temperature will accelerate the growth and development process of corn and shorten reproductive growth. It may also lead to worsening diseases and insect pests, accelerate the rapid decomposition of soil organic matter, increase the amount of fertilizer and pesticides, and increase production costs, thereby reducing yield.

To deal with climate crisis, in addition to cherishing the current food, you can also make your daily life lower carbon!

Coffee, red wine, honey ... These situations sound like a joke, but with the changes in climate, maybe in the future, there will be no coffee, no red wine, even corn and honey will become luxury!
