Improvements in the area of uranium extraction would contribute to reducing the possibility of environmental damage by using uranium as fuel.
Explanation:
Having a uranium rod as a nuclear fuel generating energy in a fission reactor is not simple, it is a complex and costly process since the uranium ore is extracted, generating in its different stages negative environmental impacts through waste and shipments of radioactive material.
Improvements in uranium extraction would significantly reduce the environmental impact of this process, mainly in water.
Hot-air balloons float because the air caught inside the balloon is heated up by a burner, making it less dense than the air outside. As the burner heats the air, it expands and some of the air escapes; that's what makes it less dense
