• Urbanization, pollution, and overfishing

• Hunting, urbanization, and pollution

• Climate change, overfishing, and hunting

Answer explanation

The major threats to the Amazon rainforest include deforestation, illegal logging, mining, agriculture, and climate change.

How does deforestation affect the biodiversity of the rainforest?

• Deforestation reduces biodiversity by destroying habitats and disrupting ecosystems.

• Deforestation has no impact on the biodiversity of the rainforest.

• Deforestation increases biodiversity by creating new habitats.

• Deforestation only affects a small portion of the rainforest's biodiversity.

Answer explanation

Deforestation reduces biodiversity by destroying habitats and disrupting ecosystems.

What are some strategies for sustainable management of rainforest resources?

• Neglecting the needs of local communities and their livelihoods

• Encouraging unsustainable harvesting practices

• Allowing unrestricted logging and deforestation

• Implementing strict regulations on logging and deforestation, promoting sustainable harvesting practices, supporting local communities in sustainable livelihoods, establishing protected areas and national parks, and encouraging reforestation and afforestation efforts.

Answer explanation

Strategies for sustainable management of rainforest resources include implementing strict regulations, promoting sustainable practices, supporting local communities, establishing protected areas, and encouraging reforestation and afforestation.

What are the benefits of conserving biodiversity hotspots?

• Preserving unique and endangered species, maintaining ecosystem services, promoting sustainable development, and supporting scientific research and education.

• Increasing the risk of extinction for endangered species

• Disrupting ecosystem balance

• Limiting economic growth and development

Answer explanation

Conserving biodiversity hotspots benefits by preserving unique and endangered species, maintaining ecosystem services, promoting sustainable development, and supporting scientific research and education.

What is the significance of ecosystem services provided by biodiversity?

• Ecosystem services have no significant impact on human well-being.

• Ecosystem services are only important for the survival of plants and animals.

• Ecosystem services, such as pollination, water purification, and climate regulation, are essential for human well-being and the functioning of ecosystems.

• Ecosystem services only benefit a small portion of the human population.

Answer explanation

Ecosystem services, like pollination and water purification, are vital for human well-being and ecosystem functioning.
