A bird species in danger of extinction has a population that is decreasing exponentially (Upper A equals Upper A 0 e Superscript kt). Six years ago the population was at 1400 and today only 1000 of the birds are alive. Once the population drops below 300 , the situation will be irreversible. When will this happen?

After 14 years the population of these birds reached to 300.

Explanation:

The main reason for the extinction or decrease in population of these birds are over hunting or the introduction of invasive species in the ecosystem. Due to over hunting by humans many beneficial species are extinct which causes imbalance in the ecosystem which can't be corrected. These population should be increased by providing a suitable environment to these birds.
