3. Technology,society and the
environment: humans use technology as
a tool.

4. Technology and the enviroment.
●
Pollution and waste: substances that can be
harmful to living organisms into the environment

5. Depletion of energy resources: due to
extensive,growing use of non-renowable
fossil fuels.

very serious repercussions.

human activity.

9. Air pollutants, water pollutants
and land pollutants.

10. Air pollution: causes, pollutants and
effects.

11. Water pollution: causes, pollutants and
effects.

12. Land pollution: causes, pollutants and
effects.

13. Municipal solid waste (MSW)
●
Landfille site: is mainly generated by households.

14. Different containers for waste: for
recycling.

15. Depletion of resources and
environmental policies:
●
Energy resources are going to run out, and the fuels
we use cause environmental problems. We therefore
need to use clean renewable energies.

16. Alternative energy sources.
● Biofuels: obtained from organic waste.
●
Bioethanol: extracted ●
Biodiesel: extracted
from sugar cane. from used oil.

17. Biogas: extracted the power plants.

18. Nuclear fusion energy: which generates less
radioactive pollution.

19. Fuel cell: which converts cheminal energy into
electrical energy.

20. Environmental policies.
● Fiscal policies. ● Incentives and
subsidies.

21. Policies promoting organic farming.

22. Sustainable development: is development that
meets the needs of people in the present without
compromising the ability of future generations to
meet theirs.
