14 billion pounds of garbage are dumped into the ocean every year. Most of it is plastic.

Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year.

FACTS

Mangroves serve as storm buffers by reducing wind and wave action in shallow shoreline areas

In probability theory and statistics, the variance is a measure of how far a set of numbers is spread out.

Definition:

Standard DeviationDefinition: a measure of the dispersion of a frequency distribution that is the square root of the arithmetic mean of the squares of the deviation of each of the class frequencies from the arithmetic mean of the frequency distribution; also : a similar quantity found by dividing by one less than the number of squares in the sum of squares instead of taking the arithmetic mean.
