Save the tigers Someday‚ we may never see tigers again because tigers are on the critically endangered list‚ which is why the National Zoo was celebrating Global Tiger Day. This is happening because of poaching and habitat changes. Large plantations have replaced a lot of tiger habitat in several tropical range countries.

In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction
