Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
<h3>What are active volcanoes?</h3>
Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.
These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.
Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.
In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
