we did this in school..it is kinda gross but it works....collect a significant amount of cow dung and put it in a big enough earthen container. Leave some space there, do not fill to the top. Now seal it. The lid should have a hole in it through which you can attach a metal pipe like structure with a tap mechanism.
Now leave it sealed for 2-3 weeks. Now attached the other end of the pipe to a stove like mechanism. Open the tap. Light the stove....you have bio-fuel !!
This is actually being used in rural india where there is an abundance of cattle and conventional gas is expensive to procure.
It reeks though..you have been warned!!

I try to developp a project of globale water management.
Why?
For a lot of raisons.
Globale water management is a concept of repartition of the resource and recharging of underground reserves.
Technicaly, it is very simple .
On each river bassin i catch the water excesses on the side of natural ways of water and i dig a canal which follow the same level curve with 1% slop.
All along the canal the water infiltrate slowly so as at the end of the canal there is no more water.
Like this:

If the project is apply on a large surface even all a continent it is possible to fight dryness with water of the floods .
One other important advantage is the fighting to restore climats
For now people think that the climat change comes from green effect. In fact the climat change has an other factor: the result of the human activities on water cycle and more specialy the dryness increasing all aver the world (overpumping of reserves and waterprofsurfaces)

If it's a construction project, I would suggest the United States Green Building Council (USGB) website - you could become LEED (Leadership in Energy and Environmental Design) accredited and have your project be LEED certified. Basic breakdown is: Water efficiency, sustainable sites, energy and atmosphere, indoor environmental quality, and materials and resources. Even if you don't want to go through all that, their website has lots of great tips and suggestions you may find helpful.

You can write about trees and jungles. They are a natural resources but they are beign destroyed because humans build cities, cut trees,and ect.
how to conserve it? in some countries, any tree they cut, they plant a new one. This is a good way. But in many countries they don't
Or they burn some old trees in a forest to let the younger trees to receive the sun light and to grow.
I hope it can help u

big changes begin in little accions: to wash hands has changed the health of the people in the whole world. Why you do not try a project that changes the life of the home?
