Hypothesize ways that we could stop the<br> flow of carbons into the atmosphere?
vovikov84 [41]

We can possibly stop carbon flow into the atmospehere by

  • Carbonisation process
  • Storing carbons in the organic tisues (Green carbon)
  • Blue carbon
  • Artificial carbon sinks

Explanation:

Growing carbon in the atmosphere has wreaked havoc on the natural functioning of the ecosystem. This has altered the way of the natural flow of matter in the geo-biographic cycle. Following methods can be improvised to remove carbon from the atmosphere.

  • Carbonisation process- Through this process atmospheric carbon dioxide can be stored in the natural rocks through the process of carbonisation, where elements react with atmospheric carbon under-stimulated condition to form carbonate rocks. Later these rocks are stored.
  • Storing carbons in the organic tissues (Green carbon)- Plants and trees utilise atmospheric carbon to synthesise foods and make tissues. The proliferation of plants can remove carbon from the atmosphere and store it in their organic tissues. This carbon stored in the plant tissues is often called Green Carbon.
  • Blue carbon- Marine plants and some organism utilise carbon to proliferate like phytoplankton’s and other. The atmospheric carbon us trapped in their body tissues. Later when they die, the body is decomposed and is recycled in the depths of the ocean. Hence atmospheric carbon is sequestered in the depth of the Ocean indirectly. These are often called Blue carbon.
  • Artificial carbon sinks- Artificial sinks such as natural caves, underground caverns can be used to store carbon dioxide after separating it from the air. This carbon can be later utilised into the productive use for plants growth or any other purpose.

Your dream is to live in Paris. Unfortunately, you do not speak French or have a work visa, so you can only stay 90 days or unti
Vinvika [58]

Answer:

Migration Barriers

Explanation:

This language and immigration barrier can negatively affect my decision of going to Pairs and simply discourage me from going there.

Even after travelling to Paris, the language barrier will affect my relationship with others due to restricted communication and the quality of my decisions there.

The immigration barrier will simply cut short my stay because i won't be able to secure a job due to my visa-type and thereby will receive no income. I will have to leave after my money had ran out.
