-This explosive population growth reached a peak of 2.1% growth rate in the late 1960s, the most significant demographic process since the beginning of the industrial revolution.

-The world population is expected to reach 9.1 billion in 2050 and to be increasing by about 33 million persons annually at that time.

-The population growth of the 49 least developed countries is still the fastest growing in the world, at 2.3% per year.

-During 2010-2050, nine countries are expected to account for half of the world’s projected population increase: India, Pakistan, Nigeria, Ethiopia, the United States, the Democratic Republic of Congo, the United Republic of Tanzania, China andBangladesh, listed according to the size of their contribution to global population growth.

-Globally, life expectancy at birth is projected to rise from 68 years in 2005-2010 to 76 years in 2045-2050.

-In terms of annual averages, the major net receivers of international migrants during 2010-2050 are projected to be the United States, Canada, the United Kingdom, Spain, Italy, Germany, Australia and France.

-The number of cities of one million or larger was 76 in 1950, 522 in 1975, 1,122 in 2000, and is set to exceed 1,600 by 2015. Using current population projections to 2050, most of the forthcoming growth in population will be in cities, with poor countries having “to build the equivalent of a city of one million people each week for the next 45 years” (Cohen, 2005).

-1.5 billion animals moved across US border by importers from 2000-2006

-That equals 5 pets per person in the US

-90% came from wild populations where disease testing is not mandated

-More than 67% came from Southeast Asia

-52% were only identified by Class

-13.6% were classified by Species

-11.9% were identified by Family

-11.1% were labeled only by Genus

-3.9% were identified by Order

-7.5% of animal imports were labeled as unknown

Basking sharks filter up to 1,500 gallons of water per hour

The smallest is a lantern shark, averaging just 8 inches

The largest fish in the world is the whale shark and can reach lengths of over 40 to 60 feet

The fastest shark is the Mako, which has reached speeds of more than 45 miles per hour

Blue sharks have been tracked swimming more than 10,000 miles

Sharks may hear a fish a mile away

Sharks can smell blood in the water from 1/3 of a mile away

The Spiny dogfish has a gestation period close to 2 years, which makes it one of the longest of any animals

Spiny dogfish females are thought to reach breeding age at 35 years

Dusky shark females reach breeding age at 20 years

The smalltooth sawfish population has declined by 99%

The IUCN estimates that 20% of sharks are in danger of extinction

Worldwide shark takes have tripled since 1985

Tens of millions of sharks are accidentally caught as bycatch in commercial fisheries each year

According to Oceana, “estimates of the total number of sharks killed each year for their fins range from 26 to 73 million per year.”

-The estimated mallard population is 8.5 million birds, a 10 percent increase over last year’s estimate of 7.7 million birds and 13 percent above the long-term average.

-The estimated population of 3.1 million gadwall is similar to last year’s estimate and 73 percent above the long-term average.

-At 7.4 million, the estimated population size of blue-winged teal is the second highest on record, while green-winged teal numbers were at an all-time high of 3.4 million. Estimates for both species are well above their long-term averages (60 percent and 79 percent, respectively).

-The 3.2 million estimate for northern pintails is 23 percent more than last year but 20 percent below the long-term average.

-The estimated number of one million redheads is similar to last year and is 62 percent above the long-term average.

-The canvasback estimate of 662,000 is 35 percent more than last year’s estimate and similar to the long-term average.

-The estimated abundance of northern shovelers (4.4 million) is 25 percent more than last year and 92 percent above the long-term average.

-The scaup (lesser and greater combined), estimate of 4.2 million, is 12 percent greater than last year but 18 percent below the long-term average.
