Resources, Human Impact, Environmental Parameters

Why should we remove an invasive species?

• They won't be able to survive in a new environment.

• They will eat native species and cause other species to decrease.

• We should not remove them and let nature be.

Salt water is an abundant resource but unusable for irrigation and drinking. As demands on freshwater sources increase, the use of desalination processes to remove salt from ocean water is increasing. A concern of desalinating water is the large amounts of recovered salts that are returned to the ocean. Which of the following describes the most likely impact of desalination on the surrounding ocean environment? 

• Methane gas would pollute the ocean environment as shoreline organisms begin to die and decay.
• Alteration in ocean salt levels would cause loss of species and unbalanced populations in marine food webs.
• Nonrenewable resources in the ocean environment would become depleted and upset the ecosystem's balance.
• Increased levels of salts and minerals in the ocean would result in overpopulation of marine bivalves due to strengthened shells

New fuels are being produced by converting corn and grasses into compounds containing alcohols that can be broken down for energy in various engines. The purpose of this research is to

•  reduce the use of nonrenewable resources.
• increase the rate of air pollution.
• reduce the rate of homeostasis in organisms.
•  cause a loss of biodiversity in the rain forests.
