How does low genetic diversity increase the risk of extinction for species?

How does narrow geographical range increase the risk of extinction for species?

• Narrow geographical range decreases competition with other species, lowering the risk of extinction

• Narrow geographical range limits the ability of a species to adapt to changing environmental conditions and increases the risk of extinction due to natural disasters or human activities.

• Narrow geographical range allows for more genetic diversity and reduces the risk of extinction

• Narrow geographical range makes it easier for species to find food and shelter, reducing the risk of extinction

Which of the following INCREASES your IB ESS teacher's ecological footprint the most?

• Your teacher flies in an airplane across to the other side of the country each year.

Environmental Impact Assessments ___.

• should be done before a project begins

• should make forecasts about both positive and negative impacts of a development

• should suggest ways to limit (mitigate) the effects of a development

• have uniform global standards

Answer explanation

Sadly, there are no common EIA standards from one state to another state and less commonality from one country to another. This lack of common standards makes it harder to compare EIAs from one region of the world to another.
