Write a speech to the students of your school on the Topic "Saving our environment". In your speech you should define the term Environment and highlight the various types of pollution that affects the environment.
Identify some of the main causes of pollution and state the effects on humans.
Finally, suggest ways by which the youths of the nation can help to Save our Environment from pollution. {25 marks}

The word environment meant the conditions we live in. Our environment is being polluted. That means that our living conditions are going to get worse, unless we change things. For example, the burning of fossil fuels pollutes our atmosphere, raising temperatures around the world. This smoke can also be dangerous to humans. We are also filling our oceans with plastic. Some of this is microplastic, which are plastic pieces that are small enough to be swallowed by fish. If the animal that eats this survives, we might catch it and eat it, harming ourselves. These plastics can even be so small that we breathe it in without even knowing it. However, we can still fix this. By cleaning our oceans, slowly transitioning to clean energy like nuclear energy, or renewable energy, like solar power, we can avoid burning off the rest of our fossil fuels, and polluting our atmosphere. Scientists are working towards creating machines to pull pollutants out of our atmosphere, so that once we stop burning fossil fuels, we can remove what we already released. Our youths can make positive changes too. We could plant trees, which remove carbon from our atmosphere naturally, and we can petition for better regulation of fossil fuels, until our nations are prepared to completely stop burning  fossil fuels. Our environment is being threatened, and we need to stop its decline before we are too late.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
