From nuts to kelp: The 'carbon-negative' foods that help reverse climate change

From nuts to kelp: The 'carbon-negative' foods that help reverse climate change

Eating low-carbon foodsżywność o niskiej zawartości węgla helps reduce emissionsemisje, but some foods actually suck uppochłaniać carbon from the atmosphere, leaving the climate in a better place.

B2

However, there are some foods that remove more greenhouse gases than they emitemitować, often referred to as "carbon negative" foods. These foods leave the climate better than they found itpozostawić klimat w lepszym stanie niż go zastali. Producing and eating more of these could help reduce the carbon impactzmniejszyć wpływ węglowy of our food and, in some cases, restoreprzywrócić ecosystems in the process.

B2

When plants grow, they take carbon dioxide (CO2) from the air, but when we (or animals) metabolisemetabolizować these plants, this CO2 usually gets released straight back into the airz powrotem do powietrza.

These removalsusunięcia last until the trees reach maturitydojrzałość, usually at around 20 years. If the trees are used to make long-lasting wood productstrwałe produkty z drewna at the end of their life, this carbon can remain stored for much longer.

B2

For all the potential of carbon negative foodsżywność o ujemnej emisji dwutlenku węgla, they may always only make upstanowić a small part of our diets; there just aren't enough products with carbon negative potential, and regenerativeregeneracyjny practices probably can't offsetzrównoważyć high emissions foods. So, we need other strategies for carbon negativityujemna emisja dwutlenku węgla too.

While carbon labellingetykietowanie węglowe and new technologies are vitalkluczowy for our shift to carbon negativitynegatywność, swapping fromzamiana z products that use lots of land (generally meat and dairy) to products that use little land (generally plant-based foods) is probably the most effective way to make our diets carbon negativeujemny węglowo.
