Small changes to help save theplanet Recycle; Reduce the use of fossil fuels; Pay attention how we use the water; Try not to use your car so much. Instead, usepublic transport; Use fluorescent light bulbs; Use as many natural light as you can; Don’t let the electronic devices in stand-by; Use rechargeable batteries; Try to use your email instead of paper;
Conclusion With this project work we learned that there is manyenvironmental disasters and the most part of the natural disastershave a small help from mankind. The environmental disasters are very dangerous and can put inrisk thousands of lives (humans and animals) and a lot of speciesloses their habitat which can cause the extinction of manyspecies. We also learned that with small changes at our homes and in ourdaily lives we can make the difference and help save the planet.
