Endangered dolphins are a huge concern in our actual society. Why is it a problem? Well, first of all, if such specie like the dolphin is endangered, it means that if this situation is not dealt with properly, soon we might see their specie disappear from our oceans.
What kind of problem could this create for both their environment and their ecosystem? This would create a huge imbalance in the food chain. No dolphins to eat some creatures then there would be too many. Too many of them means less food for each one and since their food might be marine plants, they will not grow fast enough to feed everyone.
As a result, both former dolphin's preys and the plants will gradually disappear as well. Is it really the kind of environment that we want to leave to our children?
That is why endangered dolphins must be well protected by environmental laws such as the laws protecting common dolphins.
Why are dolphins endangered? There are three main reasons why dolphins are endangered and all of them are related to humans.
The first reason is since both tuna and dolphins follow the same routes, dolphins get caught in the fishermen's nets which are meant to catch tuna. In this case, they get fatally hurt or they drown as a result of it.
The second reason is fishing for use in human's cuisine. Nowadays, dolphins are protected by laws but nonetheless between 200,000 and 500,000 dolphins were victimized by fishermen during the 1960-1972 years. Also, even if some laws protect dolphins, it allows a certain amount of dolphins to be accidentally caught which still has a negative impact on the dolphins' species.
The last but not least is pollution. Since humans are polluting rivers, seas and oceans, it affects dolphins. Also, since the dolphin is at the top of the food chain, the chemicals that pollute its habitat create the highest level of concentration of these pollutants in its body. As a result, diseases, difficulty to reproduce or even death take their toll on these species.
The endangered dolphins' species are: the Indus River dolphin and the Baiji also known as the Yangtze River dolphin. The Ganges River dolphin and the Amazon River dolphin are currently considered vulnerable. Let's protect endangered dolphins!
