What prediction can you make about future levels of carbon dioxide (co2) in the atmosphere? ?

At least one million of species will be in at risk of extinction.  

Explanation:

According recent studies of the increase of particles of carbon in the atmosphere, we are in a big risk due to this situation.

For example at may of 2019 is estimated 415.26 ppm. It is the first time in the human history since 1958 that carbon dioxide in the atmosphere reach that quantity.

For this reason is predictable that will be a risk of extinction.  

The causes of this matter would be study in another question.

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
