1. burning fossil fuels

Because of too many mosquitoes which they tend to run away from them ("National
Geographic - Strange Days on Planet Earth -Part 2of4- One Degree Factor", 2011).

3. According to van den Broeke, (2010) temperature increase in the Northern part has resulted
in melting of ice. Melting of ice significantly affect the natural ecosystem of animals.
Examples include
o Seal population- melting of rice will reduce the seal population because ices offer
a place of birthing, resting and raising the pups of the sea,
o Polar bears which depend on ice to hunt; after the ice has melting polar bear will
be surviving for periods without hunting hence will not have food to feed on
which will reduce their productivity.
o Walrus is the other group of animals that rely on floating ice to hunt. When the
ice has melted, Walrus will be left without anything to find because hunting will
be a challenge.
o The freshwater ecosystem will also be affected by an increase in temperature.
This is because, the high-temperature rise, species such as arctic char are unable
to spread geographically because they cannot compete with species present in
warm waters.
o Increase in temperature will increase the number of organic chemicals present in
ice, permafrost, and snow which will negatively affect the aquatic life.
o The Aboriginal people rely on seals, caribou, reindeer, and walrus for food. When
the temperature changes there is the inadequacy of sea ice which threatens the
survival of walrus hence assessing the animals becomes difficult. With a change
