This 400-500 word informational science passage for grades 6-8 explores Indonesia's tropical peatlands and their critical role in carbon storage. Students learn how peat forms from partially decomposed plant material in waterlogged conditions over thousands of years, creating one of Earth's most concentrated carbon stores. The passage explains the carbon cycle connection, the threats from drainage and agricultural conversion for palm oil production, and the resulting carbon emissions and fires. Aligned with NGSS Earth Science standards MS-ESS3-3 and MS-ESS3-4, this lesson connects human activities to climate systems. The passage includes audio integration, vocabulary development with 8-10 key science terms, Spanish translation, a simplified version for struggling readers, comprehension questions, writing activities, and graphic organizers. Students examine cause-and-effect relationships between land use changes and atmospheric carbon, making this an essential lesson about wetland ecosystems and climate solutions.

Deep in Indonesia's tropical forests lies one of Earth's most important carbon stores: peatlands. Peat is a type of soil made from plant material that has piled up over thousands of years. These plants do not fully decompose because the ground stays waterlogged. Without oxygen in the wet soil, bacteria and fungi cannot break down the dead plants completely. Instead, the plant matter accumulates layer upon layer, forming thick deposits of peat.
Indonesia's peatlands cover a relatively small area but hold staggering amounts of carbon. Scientists estimate these wetlands store about 55 billion tons of carbon. That represents decades of plant growth locked away in the soil. The waterlogged conditions act like a natural freezer, preserving the carbon instead of releasing it into the atmosphere. This process keeps carbon dioxide out of the air, which helps regulate Earth's climate.
Problems arise when peatlands are drained and cleared for agriculture. Farmers often convert these areas to grow crops like palm oil. When water is removed, oxygen enters the soil and decomposition speeds up dramatically. The dried peat releases its stored carbon as carbon dioxide gas. Evidence shows that drained peatlands can release several tons of carbon dioxide per acre each year. Even worse, dried peat becomes extremely flammable. Fires can ignite and smolder underground for months, sending massive amounts of smoke and carbon dioxide into the atmosphere.
In 2015, Indonesia experienced severe peatland fires that burned for weeks. The fires released more carbon dioxide in some days than the entire United States economy produced. The thick haze affected millions of people across Southeast Asia. Scientists explain that protecting and rewetting degraded peatlands can reverse this damage. By raising water levels again, decomposition slows and the peat stops releasing carbon.
Peatland conservation matters because these ecosystems play a major role in the global carbon cycle. Protecting Indonesia's peatlands helps prevent climate change while preserving unique habitats for plants and animals. International efforts now focus on rewetting drained areas and finding sustainable alternatives to peatland agriculture.
Interesting Fact: If all of Indonesia's peatlands were drained and burned, they would release as much carbon dioxide as burning all the world's forests combined.
What is peat made from?
Partially decomposed plant materialVolcanic ash and mineralsCrushed rocks and sandDried mud and clay
Why don't plants fully decompose in peatlands?
The plants are too tough to break downThere are no bacteria in tropical areasThe waterlogged soil lacks oxygen needed for decompositionThe temperature is too cold for decomposition
Approximately how much carbon do Indonesia's peatlands store?
5 billion tons55 billion tons500 billion tons5 million tons
In the passage, what does the word 'flammable' mean?
Able to absorb water easilyAble to catch fire and burn easilyAble to store carbon for long periodsAble to support plant growth
What does 'rewetting' mean in the context of peatland conservation?
Adding fertilizer to improve soilPlanting new trees in cleared areasRestoring water levels to drained peatlandsRemoving dead plants from the surface
Based on the passage, what can be inferred about the relationship between oxygen and carbon storage in peatlands?
More oxygen leads to better carbon storageOxygen levels do not affect carbon storageLess oxygen helps preserve carbon in the soilOxygen creates new carbon in peatlands
Why are the 2015 Indonesia peatland fires significant for understanding climate change?
They showed that fires can release massive amounts of stored carbon quicklyThey proved that peatlands cannot be protectedThey demonstrated that fires help peatlands growThey showed that smoke does not affect air quality
If a farmer wanted to use peatland for palm oil production without harming the climate, what would be the best approach based on the passage?
Drain the peatland completely before plantingBurn the peat to clear the land quicklyFind sustainable alternatives that don't require draining peatlandsRemove all the peat and replace it with regular soil
True or False: Waterlogged conditions in peatlands help keep carbon dioxide out of the atmosphere.
TrueFalse
True or False: Once peatlands are drained, they cannot be restored to store carbon again.
