国家公园

This strongly suggests that for the country Illium, the best way to preserve public lands is to charge people more money when they are using national parks and wilderness areas for activities with heavy environmental impact.

这有力地表明，对于Illium国来说，保护公共土地的最佳方法是，当人们使用国家公园和野地从事某些会带来沉重环境后果的活动时，就应该向这些人收取更多的费用。

The arguer cites this as a strong indicator that the country of Illium should charge people more money for activities with heavy environmental impact when they are using national parks and wilderness areas.

论述者将此援引为一种强有力的标志，说明Illium国应该向人们收取更多的费用，以同意人们在使用国家公园和荒郊野地时可从事某些会产生沉重环境后果的活动。

The argument is fatally weakened by merely calling for the collection of such fees without indicating how those fees will be spent to safeguard the future of the national parks and wilderness areas of Illium.

如此看来，这项论述受到了致命的削弱，因为它仅仅号召去征收这些费用，却并不表明，这些费用将如何被用来保护Illium国的国家公园和荒郊野地的未来。
