Destruction of ocean habitats by pollution today means that the organisms living there may not survive in the future. By polluting the oceans, humans are

• helping advance economic gains by using resources wisely

• altering the equilibrium of ocean ecosystems

• decreasing the rate of species extinction

• increasing the stability of the oceans

Solar and wind power are options available to people interested in producing electricity while reducing their reliance on fossil fuels. A benefit of using these alternative energy sources is that they

• preserve natural resources for future generations

• increase the number of jobs required for mining coal

• ensure that supplies of fossil fuels will never decrease

• cost more to generate than all other sources of electricity.

A species of predatory wasp is introduced to control an insect pest. A possible negative consequence of this action is that the new predatory wasp may

• limit the population of the insect pest

• prey on beneficial insects

• disrupt mineral availability in the ecosystem

• cause an increase in pesticide-resistant plants

The World Wildlife Federation's recent report indicated that there has been a 60% decline in the size of monitored wildlife populations in just over 40 years. The most likely factor contributing to this decline was

• animals reproducing successfully

• the destruction of many natural habitats

• passing environmental protection laws

• the introduction of native species into habitats

• C) Deforestation removes trees that produce carbon dioxide through the process of photosynthesis.

• D) Deforestation immediately increases ecosystem stability needed in the burned area.

Which action by humans has most likely contributed to climate change?

Some salmon have been genetically modified to grow bigger and faster than wild salmon. They are grown in fish-farming facilities. These genetically modified fish should not be introduced into a natural habitat because:

• the salmon would recycle nutrients at a rapid rate

• their rapid growth rate could cause them to outcompete native salmon

• they would not have enough oxygen for survival

• they would reproduce asexually once they were released.
