Features of the river
The La Plata river can be clearly seen even from space thanks to the enormous size. Its basin occupies about 20% of the area of the continent. The water in La Plata has a brown color due to dissolved sludge. Large ships can operate only on a small stretch of the river. The track constantly grows shallow because of the sand brought by the tides. Quite often on the river work on the artificial deepening of the fairways.
At La Plata there are many densely populated areas of the South American continent. The river is an international watercourse resources which are used by 5 countries:
As you increase the number of people living on the banks of La Plata, and development of local industry, increasing anthropogenic change in the river basin. Countries using the resources of La Plata, we have to unite and take various measures to prevent the occurrence of environmental problems.
Industry and agriculture
Water resources of La Plata began to intensively use in the second half of the twentieth century. The development of the construction and furniture industry led to the destruction of forests, which caused the destruction of the banks of the pool. To date, survived only 5% of vegetation cover.
Industry La Plata
On the banks of the river concentrated a huge amount of HPS. The biggest of them provides electricity to about 90% of the needs of Brazil. The estuary and its tributaries abound in the reservoirs, the number of which is 20 and growing. Intensively used the water of La Plata for irrigation of agricultural land. By the early XXI century the area of land requiring irrigation, amounted to about 18 million hectares.
On the banks of the estuary there are few unique vegetation. Most here there are marshy plants. Despite the paltry number of primitive forests, deforestation continues.
Agricultural lands often grow wheat and corn. Other cultures are less common due to unsuitable climatic conditions.
In La Plata there is a huge amount of different species of fish. Only in the pond you can find rare species of Dolphin, which is named after the river La Plata.

These types of reptiles are rare, and to catch them or collect the eggs is strictly prohibited.
Often on the river La Plata there are floods. Since 1980, their number and scope have increased significantly. Environmentalists believe that part of the reasons for this phenomenon were the work of hydroelectric power stations and global warming. Also increasing the intensity of floods associated with global Oceanography atmospheric phenomenon El niño.
The massive flooding that occurred in recent years, La Plata, dated April 2013. The flooding led to numerous destructions of residential and industrial buildings and casualties.
