Explanation:

1. Supply, Demand, and Scarcity

When resources are limited, supply (available quantity) and demand (desired quantity) interact more critically. Scarcity (limited resources) creates competition for access, as demand may exceed supply, influencing pricing, allocation, and access to goods/services. For example, in a drought, water demand stays high but supply drops, so supply - demand dynamics (like higher prices, rationing) determine who gets water.

• Harm to the Environment: Human development (e.g., urbanization) and industry cause harm via pollution (air, water, soil from factories, vehicles), deforestation (for infrastructure/agriculture), habitat destruction (displacing species), and resource over - extraction (mining, overfishing). Industrial activities like manufacturing release pollutants (e.g., CO₂, toxic chemicals).
• Benefits: Development/industry bring economic growth (jobs, income), technological progress (cleaner energy, efficient resource use over time), improved living standards (better healthcare, education), and infrastructure (transport, utilities) that can support environmental protection (e.g., green tech R&D).

• When a Region Has Many Resources: A resource - rich region often experiences economic growth (from resource extraction, processing), population influx (for jobs), infrastructure development (to support industry), and increased trade (selling resources/processed goods). However, it may face “resource curse” risks (over - reliance on resources, corruption, environmental degradation).
• New Industries Change a Region: New industries (e.g., tech, renewable energy) diversify the economy (reducing resource - dependence), create high - skill jobs, attract a different workforce (younger, educated), and transform the region’s culture/economy (e.g., from a mining town to a tech hub), while also driving infrastructure (e.g., broadband for tech) and environmental improvements (if industries are green).

Answer:

Supply and demand become critical in scarcity as demand often outstrips limited supply, driving competition for access (e.g., via pricing, rationing). Scarcity restricts resource availability, so supply - demand mechanisms (like price signals) allocate access, with those willing/able to pay (or with priority) gaining access.
