Answer:
11 billion
Explanation:
The global population is constantly on the rise. There are significant demographic differences around the world, and i general they can be taken regionally.
- Europe, the Americas, and East Asia tend to have low birthrates and low mortality rates. This leads to aging populations, and gradually the populations will start to stagnate and even decrease.
- On the other side, Africa, South Asia, Southeast Asia, the Middle East, are regions that have very high birthrates, and even though the mortality rates are much higher than the previously mentioned regions, they still manage to have big increase in their population.
- In a way, this disproportion is actually balancing the global population, so its rise is not as dramatic as in the past. It is expected that the population will continue to rise, but that the rise will constantly go down. The estimates are that by the year of 2100, the world will have a population of just above 11 billion people, 11.2 billion to be more precise.
Answer: The brightness of our if betelgeuse were to explode as as a supernova would by getting the ratio betelgeuse to sirius. Which would then be:

After this, subsequent backwash carries the sands along with it and deposits at a right angle to the sea shore. This deposited sands and other materials connects the shore to an island and this features are known as tombolo.
