People in the tourist industry know that excessive development

People in the tourist industry know that excessive development of seaside areas by the industry damages the environment. Such development also hurts the tourist industry by making these areas unattractive to tourists, a fact of which people in the tourist industry are well aware. People in the tourist industry would never knowingly do anything to damage the industry. Therefore, they would never knowingly damage the seaside environment and people who are concerned about damage to the seaside environment thus have nothing to fear from the tourist industry.
