You will learn how changes that have been caused by humans affect ecosystems.
After completing this tutorial, you will be able to complete the following:
How have changes in world population impacted global warming?
~ As the world's population has increased in recent years, humanity's needs have grown considerably. To meet these needs, industrial production has been increased to its highest levels ever, which means more pollution is being released into the environment. The elevated level of pollution caused by industrial activity has, in turn, worsened the effects of global warming.
How have modern agricultural methods caused environmental problems?
~ Because of the increase in world population, it has become necessary to cultivate more land for agricultural purposes to provide enough food for everyone. This means destroying natural ecosystems to turn them into farmland. In addition, the indiscriminant use of pesticides to boost crop yields has also caused environmental issues.
How has our search for new energy sources negatively affected the environment?
~ Nuclear energy is a major source of energy that we recently began to explore. Unfortunately, the nuclear testing involved in learning about this type of energy has resulted in further environmental pollution.
Aside from global warming, what are some other environmental issues that face the world today?
~ Other environmental issues that face the world today include climate and weather changes, acid rain, an increase in the number of endangered species, and increasingly strained water resources.
