<span>It only adds up to 1% of the world’s oceans, but the Mediterranean sea is one of the most international waters on our planet. Nineteen nations border it, more than 10,000 species live in it and millions of people get food, work and pleasure from it. It is the feeding and breeding ground for many endangered species. Protecting this 1% could make a world of difference.</span>
Answer:
If the duration of life on Earth was on a scale of 20,000 days, the human species would be present in the Earth for approximately 9 days.
Explanation:
We can't be sure about the exactly age of the Earth, but we can base our calculus in a number between 4400 and 4600 million years, because the most accepted researches shows numbers in this span of time. We can take the average of those limits: 4500 million years.
On another hand the presence in the Earth of human species has not a precise date because of the it does not have a precise date for two main reasons, the scientific evidence does not include all the human species that existed on Earth but it is a very incomplete evidence and besides being an evolutionary phenomenon it is not easy to determine from what moment We can consider that a species belongs to the human race or not. In any case, we take the approximate date of the scientific evidence of the existence of human species in an age of 2 million years.
With both numbers we can calculate the proportion in the scale of 20 thousand years throw the following formula:
PHS = 20000 years . 2 million years / 4500 million years = 8.9 years
PHS: Presence of Human Species
There are more than one city on the High planes in Texas, and some of them are: Armadillo (190 000 people), Lubbock (270 000 or 315 000 with suburbs - it's also among the 100 most populous cities in the US!, but only 11th in Texas.), Pecos (10 000) , Odessa (110 000 )<span />
Answer:
- fragmenting states
- artificial landmasses
Explanation:
There are several ways a new state could form even if all of Earth's land was allocated to current nations. One of the possibilities is that a current state fragments to form two (or more) smaller states.
Another possibility is that nations construct artificial landmasses or habitable platforms in the oceans that are independent countries. Finally, in the future it may be possible to settle the continent of Antarctic if the Antarctic Treaty is ever not renewed.
