PROJECT WORK "THE WORLD AROUND US SPEAKS ENGLISH"

The world around us speaks English

Our natural and social environment 

1. Sustainable development

The sustainable development uses in a responsible way the natural resources without wasting them, so it produces a balance between the human activity and the environment impact.

I think this is very important, in order to improve our environment. For example: if we spend too much wood from the trees, animals will become extinct. 

2. Reduce, reuse and recycle

These are the three “R”.

Reduce means that we have to minimize the consume of things which pollute our environment. Try to waste and use less things, just what is necessary.

Reuse means to use again. We have to use things as many times as we can, not to throw them to the bin when we only use them once. The more things we can reuse, the less energy is spent making new ones.

Recycle means to throw the same materials together in the same containers in order to be able to clean them and prepare them to be used again. 

3. Renewable and non renewable energies

Renewable energies are the energies that won’t run out, like sunlight, water or wind. They are energies that we can use as many times as we want.

Non-renewable energies are the ones that will run out, like oil, natural gas, coal... 

4. Different kinds of energy

Energy can manifest in different ways: in form of movement, heat, electricity, electromagnetic radiation…There are many types of energies, but the most important ones are: chemical, nuclear, sound, thermal or calorific, mechanical, electrical, electromagnetic, hydraulic, wind, etc. 

5. Types of wastes and residues

All the human activities produce wastes and residues: household, agriculture… However the amount and nature of the wastes are very different depending on their origin. There are many types of wastes that make our planet too ugly.
