The population of the world is growing rapidly and has been since the beginning of the industrial revolution. The population has grown to over 7 billion people and is projected to reach over 9 billion by the year 2050. This will cause many problems for people around the world. Move each of the solutions to the problem they might help address.

The population of the world is over 7 billion people and will continue to grow in the near future. Women on some continents give birth to many more children per person than others. In Africa, the average rate of children per woman is 5.9 while in North America it is closer to 2 children per woman. In Europe the birth rate has dropped to around 1.5 children per woman. These differences are caused by many things. Match the characteristics of a population to its fertility and growth rates.

All organisms in an environment play important roles. Some provide food sources for other organisms, some provide habitats that organisms call home and others may even provide useful services for the human race. Several services that are provided by the unique biodiversity found in the world are shown here. Math the ecosystem service provided to man with teh ecosystem most resposible for the service. Each service will be used exactly once, but the ecosystem can be used more than once.

Many animals and plants are in danger of extinction. Scientists believe we are in the midst of the 6th mass extinction. Many things are leading to this but most believe man is playing a large roll in this extreme extinction.Identify the statements that could lead to putting a population at risk for extinction. Select all that apply.

Fred has been doing some research on the animals of Northern Canada. He studied five different species and found that each of them has been listed on the endangered species list. Some are in worse shape than others.
The first animal he studied was the polar bear. The population is still large and stable but the habitat polar bears live in is in decline because of climate change and the rising temperatures of the planet. Scientists are worried the population will decline further if things continue this way so polar bears have been listed with the hope of protecting their habitats.
Fred also found about a small rodent called the Vancouver Island marmot. This animal is in significant danger of being lost in the wild completely. They only live on islands in Vancouver and their habitats are being destroyed by clear cutting of the forest. In order to prevent their loss, most of the marmots are found in captive breeding programs to try and replace them in the wild. If this trend continues, they will be lost in the next few years.
Another mammal Fred discovered was the peary caribou. This species grazes on plant life and has unique adaptations to help it dig in small amounts of snow to reach the grasses and lichens below. Due to climate change, severe weather events have increased the depth of snow at different times of the year and it has decreased the overall population of caribou in this part of the world already. If this trend continues, the caribou may continue to decline in numbers.
He also looked into species of birds found in the area. One bird he studied was the whooping crane. This species of birds was hunted and their habitats were destroyed so thoroughly that they only had 153 mating pairs in the wild. Scientists have been working to bring them back from the brink but they are still in great danger of being lost. While there are now more than 600 birds in the wild, their natural habitats are still in danger.
Finally, he found another species of birds called the Labrador duck. At one point they had a solid population in this area but have not been seen on Earth since 1878. It is believed European settlers hunted their eggs and their food source until this population of ducks disappeared completely.Sort the organisms by their classifications from barely threatened to extinct. Place the animals name in the category in which it belongs based on the descriptions of what Fred found in his research.
