Please help need done ASAP “Which type of large-scale environmental impacts are the most detrimental? Is all human impact on the environment negative? How can we prevent the occurrence of large-scale, negative environmental impacts?”

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
