A change occurs in an environment that lasts for three days and causes an immediate, dramatic impact. What can be known about this change?
Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely eliminating those risks.
Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers. The more practical approach is to minimize and manage the health risks associated with chemical exposure.
How does mining impact the environment?
Explain why water shortages are expected to be such a widespread problem in the future.
Which is an effect of short-term environmental changes?
Explain why successful collaborative environmental efforts rely upon partnerships between government, business, and environmental groups.
Many groups have an interest in environmental issues including governments, businesses, and environmental groups, but these groups’ interests do not always overlap. Therefore, in order to keep large groups of these stakeholders from being disenfranchised from environmental efforts, their concerns and opinions need to be included in a collaborative format. If stakeholder groups are disenfranchised, their discontent is likely to be seen as an indicator that the effort was discriminatory and not fully successful.
Explain how the use of fertilizer can have a negative impact on the environment.
Fertilizer can have a negative impact on the environment, because of its high nutrient content. When fertilizer enters waterways as runoff, it causes waterways to have an excess of nutrients. This excess of nutrients causes increased algae growth. When these algae decay, they deplete the oxygen in the water, negatively impacting organisms that rely on the oxygen in the water for survival.
Explain how the use of oil as an energy source can potentially affect aquatic viability.
The use of oil has the potential to affect aquatic viability during several stages. Offshore drilling practices to acquire oil for energy use can negatively impact aquatic viability through potential contamination and disruption of aquatic habitats. Transportation of oil over the water has the potential to contaminate aquatic ecosystems through oil spills. Waste products associated with the use of oil for energy production can also cause contamination of aquatic habitats.
