IG 10 Human Impact

The sum of all living matter on Earth

• natural habitat

• population

• extinction

• biosphere

Resources that are not replaced within a relatively short time frame are __________. Metals, most minerals, oil, and coal are examples of these resources.

• nonrenewable resources

• natural resources

• renewable resources

The removal of forests to use the land for other reasons is called _______________.

• desertification

• desperation

• deforestation

• desertion

______________ causes more land to be developed and built up with human structures due to the high concentration of human population.

• Socialization

• Urbanization

• Certification

• Desertification

_____________ is the advance of desert-like conditions into areas that were previously fertile. This is often caused by overfarming, overgrazing, drought, and climate change.

• desertification

• desperation

• deforestation

• desertion

To support the claim that the consumption of natural resources by humans has a negative impact on the environment, what kinds of data would be needed to provide evidence?

• Increasing human lifespan over time and global increase in sea level

• Increasing the consumption of resources by humans and increasing biodiversity

• Increasing burning of fossil fuels by humans and decreasing use of other resources

• Increasing human population and decreasing size of habitats for plants and animals

As the human population increases, so does the consumption of natural resources. What type of impact does this have on natural ecosystems and environments?

• positive

• negative

People take down trees to produce other resources that they need. The clearing of trees affects both the availability of this renewable resource and the organisms in the area. What effect does the clearing of trees have on the organisms that live in the forest?

• The organisms will be able to use the remaining trees for habitat and resources they need to survive.

• The organisms will lose their habitat and sources of food. They need to find another area with the right habitat and resources to survive.

• The organisms will be able to use the stumps for the habitat and resources they need to survive.

• The organisms will be able to use the totally deforested land to find the habitat and resources they need to survive.

People take down trees to produce other resources that they need. The clearing of trees affects both the availability of this renewable resource and the organisms in the area. Which process below best describes a sustainable plan for the forest?

• Use the land to grow crop plants instead of trees.

• Replace the cut trees by planting new trees.

• Use the harvested trees to make reusable products.

• Convert the land to a wetland habitat for other organisms.

Based on the details in the image, which of these impacts is most likely to occur in this forest?

• More organisms will come to live in the area now that there is more room.

• All of the plants in the area will die.

• Soil will erode from the area due to the lack of living tree roots.

• The lack of trees will cause groundwater pollution.
