- 3. 3 Introduction I know youmight think that water is no big deal, but you would be surprised. There is only 1% of water, fresh drinking water and over 97% of the earth is made up of water. There are 4 steps to the life cycle Step1. The sun evaporates the sea water Step2. It makes clouds Step3. It rains and goes down the hills Step4. Its back in the sea
- 4. 4 Salinity Did you know,that seawater has a salinity of between 3.1% and around 3.8%, also sea water is not uniformly saline throughout the world! The most saline open sea is the Red Sea(that’s in the Indian sea between Africa and Asia)where the high rates of evaporation low precipitation and river inflow. The density of the surfaced sea water ranges from around 1020 to about 1029 kg/m3. Deep under the ocean, high pressure sea water could reach a density of 1,050 kg/m3 or possibly higher.
- 5. 5 Rain water tanksmay be lifeline Did you know that broken pipes can be more deadly in Wellington because of earthquakes and fault lines causing pipes in buildings to crack. And did you know that, the average amount of water is 20L per day and the minimum is 6L This, and can run for weeks or months before the emergency supplies will be restored. Reporter author Jim Cousin said “100,000 people estimated up to 20 days without access to water if a 7.5% earthquake hit the Wellington fault line”.
- 6. 6 Drag Fishing Did youknow that, drag nets can be more than 50 football fields? That’s about 1000+boats size, and just imagine how many fish get trapped in there, that’s hundreds of fish all cramped together in one net. These horrible nets are destroying fish’s habitat, because the nets drag along the bottom. This removes up to 25% of the bottom of the sea each time these nets go down. These nets are also making our beautiful marine life to become extinct, and already 70% of the worlds fish species are already Gone!!
- 7. 7 Fast facts about Oceans *Didyou know that our oceans occupy nearly 71% of our Planets? *And also, more than 97% of the planets water is contained in the oceans *The top 10 feet in the ocean hold as much as heat as our entire atmosphere *And did you know that the oceans provide 99% of the earth living space- *The largest space in our entire universe, known to be inhabited by living organisms.
- 8. 8 My action plan Ihave thought about my action plan very wisely. I have decided to concentrate on drag fishing, because this is horrible and wasteful, what these fishermen are doing to the food chain and to other marine animals. Because we are making our fishes becoming EXTINCT! I have thought the following; *put posters up all around the Wellington region * do a TV commercial about this *contact the government about what’s happening *do a video explaining my points and facts and sending it to TV people/TV3
- 9. 9 Conclusion In conclusion Ihave told you how much water there is, and how much we are wasting it. It is more valuable than gold. I know it might not seem it, but it is. If this looks bad to you, you can help. I have also stated how much salinity is in oceans and loads of facts about it too. Just remember * turn off the taps when you brush your teeth *mulch your gardens *put a trigger nozzle on your hose *sweep your path instead of watering it
