Kris Willis was very helpful and gave us ideas on saving power. Like having low windows on one side of the room and having high windows on the other, so that when the heat enters the lower windows the heat will rise to the high windows meaning the heat would pass through the whole room saving power.
We had learnt many other ideas.
Thankyou Mr (Kris) Willis
One topic they were discussing about was how we only have 1/32nd of the whole earth to grow our food. this also relates to our maths because our teacher told us to see if they're right, (and if they're wrong we need to prove it with percentages and fractions).
Another subject they were talking about was worm farms and how they help the enviroment so much. The reason worms are so effective to the enviroment is because they will eat your scraps of food besides citrus (e.g. oranges and manderines) and that will cause the worms to run away. 33% of our garbage/ litter thrown out is food, so if all of us have worm farms in our backyards well be saving 33% of our garbage having no food in our dumps (giving more space for us and more time to create more ideas towards sustainability).

Is global warming happening?
Yes. Earth is already showing many signs of worldwide climate change.
• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.
• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.
Are Humans Causing It?
The report, based on the work of some 2,500 scientists in more than 130 countries, concluded that humans have caused all or most of the current planetary warming. Human-caused global warming is often called anthropogenic climate change.
• Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trap heat near Earth's surface. (See an interactive feature on how global warming works.)
• Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can obsorb it.

My eco house is very healthy to the enviroment. See how those examples of eco houses at the top are made out of concrete,plaster and tiles, well my designed house is made with bamboo sticks and normal wood just to be extra eco friendly. Because building materials are poluting our plants/ trees instead of helping the plants to grow, (it's sort of like the eco building materials are encouraging the plants to grow).
My life style is much more simple than modern life now. All my gear and equiptment is also eco friendly, I would obveasly bring a matress and a few other home things (but i would keep my electricity bill down with only bringing about 10-15 electronics). My eco friendly gear would be items like a solar power heaters from the top of the ceiling spreading all around the rooms(to stop the heater running just shove a mat over the solar power heater), and also more items like my own recycling machine at home to prevent some native/ not native birds and other animals being killed by tangling rubbish (damaging their body and limbs, causing them to not catch prey or reach food and other reasons of them dieing).

For humans to live sustainably, the Earth's resources must be used at a rate at which they can be replenished. However, there is now clear scientific evidence that humanity is living unsustainably, and that an unprecedented collective effort is needed to return human use of natural resources to within sustainable limits.
