=Take action for water.=

animals in the streams:
The streams use to be good for our aquatic animals because their were lots of food and shelter and a good environment for them and the roots stopped sediment and rocks getting into the water. it needs to be deep for eels and shello cool and rocky for Cased Cad disflys etc

Our streams were protected by forest so the water was cool clean and full of oxygen it flowed over stoney stream beds. the branches provided food and shade for aquatic animals the roots prevented erosion and sediment entering the water. cutting down our trees has put sediment in to the water and a bad environment for our animals and less food no shade and its warmer water and no rocky bottom = sand all of it equals=polluted stream. deforestation = Erosion = sediment =stream death.

i find it scary that when we have children the might not be able to go swimming/fishing etc in the river because we have not looked after our streams and we are not able to drink from our streams because we most likely get sick.

habatats:
habitat -a place that provides everything a animal need to live. they have changed them selves so they can survive as their habitat changes. the animal has a favorite place to live. habitats can be in two - forest and streams. stream animals can live in two different environments. the trees help the animals live because they make hiding places in the leaf litter and in the trees.

deforestation:
9-3-09 WALT : i can explain how humans have changed the environment thorough deforestation. i can identify some sultans to deforestation that take in to account eco system and human needs. we have cleared most of the forest that covered ateroa to create towns cities,farms etc.

most remaining forest is in the mountains and not suitable for farming.

storm water:
1.: prevents flooding ,by channiling water from hard surfaces into drains that flow into our creeks the water is not treated

2. wast water or surage: this comes from out toilets and things we use to wash our selves and our clothes. it is treated all the solieds removed before being relesed in to our waterways.

3.drinking water: first it is pumped from the river, treated and then piped to houses for them to drink.

4.what can we do to stop this ?

by not putting cemicals in the toilet. dont put rubbish down the drains. try to not waist water.

how do you breath in a stream:
We are learning to identify the different ways aquatic animals breath.

A animals need to take in oxygen some how and release carbon-die oxide from their bodies. fish use gills ... they take in water and it washes over the gills and the oxygen goes into their body and they breath carbon dioxide.

the spiracles join to the tube which takes it in to the main organ or organs

Baby insects adapt right away to the water so they can change their spiracles to gills.

some aquatic insects like miquitcos

some aquatic insects such as a water boat man and diving beetles are juvenile

=Should we be concerned about our environment.=

yes we should be conserned because we are putting cemicals and toxins in to our storm water drains and they go into the water ways rivers/streams etc. and we go swimming in them and what if we get a mouth full of water we will be getting sick.

all our aquitic animals will die or get sick.

the animals wast goes into the stream and flows down the stream and pollots other parts of streams.

to help prevent this we could.?

fence off the stream from any animals

or put a bridge over the streams so when you move the animals they wont stop and do you know what in the stream.
