What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.

The northern part of the river, known as the Niger bend, is an important area because it is the major river and source of water in that part of the Sahara desert. This made it the focal point of trade across the western Sahara, and the centre of the Sahelian kingdoms of Mali and Gao.

Answer:
Many experts believe that the Interoceanic Highway will lead to increased deforestation in the Amazon Rainforest.
Explanation:
The Amazon Rainforest is located in South America and it is the largest rainforest in the world. This rainforest though has been under immense pressure because of the destruction of it by human activities and interests. The Amazon Rainforest is shrinking rapidly and if this tempo continues it will be gone in the near future and the whole world will feel the consequences.
Apart from the opening space for agriculture, mining, ranching, urbanization, this rainforest is predicted to suffer losses because of the Interoceanic Highway as well. This highway is a project with which there will be a highway starting from the Pacific coast in Peru and ending at the Atlantic coast in Brazil. A big portion of this highway will pass through the Amazon rainforest and with it a lot of deforestation will take place. While deforestation itself will have terrible effects, the biodiversity will suffer because its territory will be cut and separated, and a lot of animals will be killed on the highway by the traffic.
