Question

b. mining and clear cutting in the canadian shield
canadas mining industry is concentrated in the canadian shield region which surrounds hudson bay. this area contains large deposits of gold, silver, copper, zinc, lead, iron ore, uranium, and nickel. although the mining industry is very lucrative, the processes used to extract canadas mineral wealth (i.e., blasting and digging) often result in environmental degradation, particularly in the areas around the mines themselves. sulfur dioxide released from mining equipment reduces the air quality, and chemical runoff from mining processes often contaminates water supplies. the canadian government has passed legislation to limit the amount of mining - related pollution allowed in its waterways, namely in an effort to protect fisheries and seafood safety.
canadas timber industry is also important to the nations economy. canadas forests are a source of lumber, plywood, and wood pulp. like mining, however, there is an environmental downside to the timber industry. the destruction of natural habitats caused by clear - cutting is critical. clear - cutting is cutting down all trees in a certain area leaving no trees behind to grow. additionally, the heavy machinery used for logging frequently compacts the soil of the forest floor such that new growth is hindered. the canadian government has done quite a bit in recent years passing laws to limit the damage associated with deforestation. as a result, canadas deforestation rate is currently the lowest in the world.

1. name three valuable natural resources found in the canadian shield?

Explanation:

To answer this, we refer to the text: "This area contains large deposits of gold, silver, copper, zinc, lead, iron ore, uranium, and nickel" (mineral resources) and the timber industry section which mentions forests (lumber, plywood, wood pulp source). We pick three from the mineral list or include timber.

Answer:

Three valuable natural resources in the Canadian Shield are gold, silver, and timber (or any three from gold, silver, copper, zinc, lead, iron ore, uranium, nickel, or timber-related resources like lumber from forests). For example: 1. Gold 2. Silver 3. Timber (or gold, silver, copper; etc.).
