Write TWO short-term and TWO long-term effects of unmanaged waste
Answers
Explanation:
SHORT TERM EFFECTS OF UNMANAGED:
When a chemical pollutant enters a body of water, it can impact surrounding wildlife, watershed and residents. For example, if chemicals get into to a freshwater supply that people and/or animals rely on for drinking, it may no longer be safe for consumption or sanitation purposes. Toxic releases from industrial plants into the environment and agricultural runoff can threaten water supplies in the short term.
LONG TERM EFFECTS OF UNMANAGED:
Fertilizers or sewage can introduce chemicals containing nitrate or phosphate into bodies of water. Nitrate and phosphate are food for the algae in water. An overload of these chemicals will cause the algae to bloom. As the excess algae die and decay, dissolved oxygen is used up and the overall quality of the water is degraded. Aquatic life dies from oxygen deprivation.
When emissions from industrial plants like sulfur and nitrogen oxides enter the atmosphere, they can produce acid rain. Acid rain can weaken plant life, stress marine animals and cause the soil to leach toxic metals. In some cases, chemical pollution can kill populations of beneficial species that support ecosystems, like bees.
When long-term exposure to chemical pollutants cause native species within an ecosystem to die, the area experiences a loss of diversity and becomes more vulnerable to invasive and undesirable species.
