Conservation: Using Our Environment and Resources Sustainably

The video discusses the importance of using environmental resources sustainably, focusing on forests and fish stocks. It highlights the role of education in promoting sustainability and addresses threats to biodiversity, such as climate change and habitat destruction. The video emphasizes the need to maintain biodiversity for ecosystem health and outlines conservation strategies, including protected areas and captive breeding programs.

What is a key strategy for using forests sustainably?

• Planting trees only in urban areas

• Using only mature trees for logging

• Allowing unrestricted tree felling

• Establishing protected areas where no trees can be removed

Why is education important in sustainable resource management?

• It reduces the need for protected areas

• It increases the number of resources available

• It eliminates the need for quotas

• It helps the public understand and support conservation efforts

What is a major cause of species extinction?

• Overpopulation of species

• Excessive genetic variation

• Climate change and habitat destruction

• Increased biodiversity

How does maintaining biodiversity benefit ecosystems?

• It reduces the need for nutrient recycling

• It ensures that all species become dominant

• It helps organisms survive environmental changes

• It allows ecosystems to function independently

What role do peat bogs and rainforests play in the carbon cycle?

• They increase the amount of carbon in the soil

• They release carbon dioxide into the atmosphere

• They store carbon that might otherwise become atmospheric CO2

• They have no impact on the carbon cycle

What is a benefit of maintaining genetic variation in a population?

• It decreases the need for conservation efforts

• It makes species more vulnerable to diseases

• It increases the chance of survival during environmental changes

• It reduces the likelihood of species survival

What is the purpose of seed banks in conservation?

• To store seeds and prevent plant extinctions

• To eliminate the need for protected areas

• To increase the genetic variation of animals

• To reduce the number of plant species
