Documentary: The Impact Of Global Warming

In the documentary “The Impact of Global Warming” it showed many ways of how global warming can effect and is effect our society and our planet. One of the impacts of global warming that the documentary addressed was the rise in sea level. There are many causes that effect the rise in sea level but one specific effect is the melting of glaciers and ice caps. When our temperature increases dramatically high it causes many of the glaciers that are situated across the globe to melt, whether its little or a lot, it does have effect on the sea level. For example, many people in the Himalayas are dependent on meltwater rivers which supply their drinking water, if the sea level rises it will contaminate their water supply. Another effect of the rise in sea level …show more content…
One of the causes in the decrease in salmon catching is due to the rise in sea temperature. In the Film it stated that in the 90s the sea temperature was much warmer than it is today. This could mean that since the water temperature is too cold for the salmon they migrate some where else where it is warmer. Another cause of the decrease in Salmon, is that not a lot of salmon are making the journey back from the ocean to fresh waters where they lay their eggs, which causes less reproduction of salmon.
One other impact of global warming that the film addressed was the problem of spruce beetles. Spruce beetles usually live in the south where there is always a high temperature. In the film it showed in recent years the beetles have been migrating to the North, which is unexpected because the North is the coldest, but with recent climate change and the increase in temperature spruce beetles can be found in Alaska. The migration of spruce beetle not only shows the drastic change in temperature but it also causes problems, in the documentary it stated that the spruce beetles in some areas have destroyed 90% of
