CWI unit 3 Environment and Sustainability (weeks 5 and 6)

How does the current drought in the Amazon compare to previous dry periods?

• It is a typical dry season, similar to past years.

• It is less severe than droughts experienced decades ago.

• It is the worst drought on record, unprecedented in scale.

• It has only affected small, isolated areas of the rainforest.

What challenges are communities in the Amazon rainforest facing due to the severe drought?

• Easy access to clean water and abundant crops.

• Improved transportation routes due to lower water levels.

• Difficulty accessing clean water, crop failures, and isolated villages.

• Increased tourism and economic opportunities.

What significant ecological event has occurred in two major Amazonian lakes during this drought?

• A boom in fish populations due to concentrated water.

• The discovery of new aquatic species.

• A mass die-off of dolphins.

• A significant increase in bird migration.

How does the Amazon rainforest typically sustain its water supply, and what is the concern if large areas of the forest die?

• It relies solely on rainfall from distant oceans; its death would have no local impact.

• Water evaporates from trees to form rain clouds, feeding itself; its death could lead to a catastrophic feedback loop.

• It stores vast amounts of groundwater; its death would only affect underground reserves.

• It captures moisture from passing clouds; its death would only reduce cloud cover.

What immediate health and visibility issues are caused by the widespread smoke in the Amazon region?

• Clear skies and improved breathing.

• Difficulty seeing and persistent coughing.

• Increased humidity and cooler temperatures.

• Enhanced plant growth and reduced allergies.

What conditions are predicted to trigger the Amazon's "tipping point"?

• When 17% of the Amazon is deforested.

• When global temperature rises by 1.5°C.

• When 25% of the Amazon is deforested and global temperature rises more than 2.5°C.

• When the Amazon stops producing rainfall for southern regions.

How much carbon does the Amazon rainforest store?

• Approximately 17 billion metric tons.

• Around 50 billion metric tons.

• About 150 billion metric tons.

• More than 200 billion metric tons.

What transformation is predicted for some regions of the Amazon if current environmental degradation continues?

• They will become more densely forested.

• They will turn into savannas.

• They will experience a permanent increase in water levels.

• They will be converted entirely into urban areas.
