For science, we have to create an ecovillage.. We decided to build our ecovillage in Calgary, Alberta because it’s the cleanest city in Canada… We need some ideas for
1) sustainable buildings: like how can we build houses/buildings without harming our environment… i already got some few ideas on how to build a sustainable building by reconstructing abandoned lots or farms, using recycled materials to build houses/buildings like recycled wood and stuff..
2) food: how we can have a sustainable diet by not damaging ecosystems.. how food will be grown, distributed, and consumed… what types of agricultural techniques need to be adopted to ensure a sustainable food supply?
3) green energy: what technologies can be used to minimize energy use and how can we communicate and access to the ecovillage by using green energy… i already have some few ideas which are solar panel-generated energy, please help me think of other ideas
4) water management: how the ecovillage will access and distribute water. how will drinkable and non drinkable water be separated? ideas: they can be separated into 2 water systems, one fore drinkable and nondrinkable.. water would be purified by the water compound and tested by the federal state government
5) waste management: how waste will be removed from the ecovillage.. what forms of eliminating would be the best and most effective? how will the 3 Rs be enforced? (reuse reduce recycle)
ideas: diverts organic waste for treatment in a biogas plant, which is then transformed into fuel for city buses. Also, methane gas from the landfill is collected and converted to electricity.
6) restoration: how can we restore an ecosystem destroyed naturally or by humans? how can elements of the eco village be used to recreate niches.. can any keystone species be supported?
thank you guys for having the time to read this.. you already read it so might as well answer some of it so it wont be a total waste of your time 🙂 links/URLs would be greatly appreciated.. this is due by tomorrow so please help 🙁

In a pond, there are so many different places…
There are niches right at the water’s edge.
There are different ones, just a few feet deeper into the water.
Then there are other niches very deep in the water, and others deep in the soil at the bottom of the pond.
There are niches associated with algae growing underwater and others growing on plants floating in the water.
There could be shady parts of the pond vs sunnier parts, where organisms that prefer one or the other prefer to grow.
If the pond is large enough, it might have an island, effecting creating a barrier from the rest of the shoreline and possibly a very specialized niche…
