Which three industries would be the most directly affected if regulations and laws regarding deforestation became stricter.

The Logging, Timber and Construction Industries would be the most affected

For obvious reasons, anyone employed in the logging industry would be severely affected if stricter laws were enforced regarding deforestation since less trees could be cut down compared to today's current quotas.

Secondly, those working in the Timber industry would also be immediately affected by the restricted availability of timber and wood in general.

Thirdly, the Construction industry, particularly in states where building structures are mostly wooden structures due to earthquakes, would suffer a tremendous pressure to remain competitive as Timber and wood prices would inevitably increase in price as availability decreases.
