term+2+topic

=TERM 2 TOPIC= So far this term we have been to Dry River vineyard, the Smith's farm and JR's orchard. At the vineyard I found it very interesting that the grape vines roots go down 2-3 meaters and that the vineyard people make them do it. At the Smiths farm I was amased to know that lots of their farm once was a river and that there has been two homesteads on their property. At the orchard I found out that 4-5 cartens of apples came of one tree. To put up the netting at the orchard would cost them $4,000,000 approx

in term two we studied climate and augrculture we did an inquary my inquary on rubbish. my big question was, What happens to our streams/rivers and soil when they are full of rubbish and chemicals? Other questions: 1: how long does rubbish take to decompose? 2: where do we dump our rubbish? 3: how can we help reduce river and soil pollution.

ANSWER TO MY BIG QUESTION: What happens to the plants: If a paddock is filled with rubbish, the grass/plants won’t be as lush and as green because the rubbish shields the grass from the rain, sun and snow. This means that the grass or plants will slowly die away. If a paddock is filled with chemicals, the chemicals will seep into the ground and into the soils water. This will make the water contaminated. The grass/plants roots will suck in the contaminated water, the chemicals may end up killing the plant.

What happens to the rivers/streams? When a stream or river is filled with rubbish, grass clippings, leaves, animal waste, dirt and other things along that line, makes the water unhealthy for the water life and plants. This sort of pollution often causes a drop in water life because of death. If there is an over-load of grass and leaves, the grass and leaves will suck out the oxygen in the water. If a stream or river is filled with/by chemicals, oil, pool chemicals, soap etc the same thing happens to the stream/river.

ANSWER TO 2: In New Zealand and many other countries we dump our rubbish in land fills. These are big lots of land that are pilled up to the top with and all sorts of other things, they are left there to rot away. On some farms they have their very own rubbish fire, this is where they burn their farm rubbish and their home rubbish (this causes air pollution)..... It was recently found that a farm in Martinborough dumps some of their farm/home rubbish and chemical wast less than 100 meters away from a small stream/river. In the world some countries dump tones and tones of rubbish every week into the lakes, rivers and oceans sounding them.

ANSWER TO 3: We can : clean up our animals waste, wash your car with eco friendly detergent, hold on to rubbish when driving instead of chucking it out the window, cook meals at home instead of buying takeaways and much, much more...
