The environmental impacts of cutting down a forest and burning the wood for heating and cooking could include I. deforestation and subsequent soil erosion. II. release of particulate matter into the air. III. a large net rise in atmospheric concentrations of sulfur dioxide.

Explanation:

Cutting trees destroys the habitat of various animal species and it harms their ecosystems. Since almost 70  percent of all the plants and animals live in forests deforestation destroys their homes, many of these species cannot live outside forests.

Deforestation also causes soil erosion, the roots of the tree hold the soil and prevent it from running off with water of being blown away by air. Once the trees are cut the soil is exposed to the harmful effect of water and wind.

Burning wood properly doesn't release particulate matter or carbon monoxide.  Wood fuel is 'carbon neutral ' and it doesn't contribute to the climate change. Wood is also low in nitrogen and sulphur compared to coal.

I. deforestation and subsequent soil erosion.

III. a large net rise in atmospheric concentrations of sulfur dioxide.
