My Argument: It is better to be sustainable.

It is better to be sustainable.

I think it is better to be sustainable because if we don't live sustainably we will use all the worlds resources, it stops animals and plants being killed unnecessarily, it will stop as much CO2 escaping into the atmosphere, it is cheaper to live sustainably and because it is better for your health.

Firstly it is better to be sustainable because we will use all the worlds resources of we aren't careful, at the moment if every one carried on as we are now, it would take not one, but five earths to sustain our needs and if we use all the worlds resources now there will be none left for future generations.

Another reason why it is better to live sustainably is because it saves plants and animals from being killed. plants and animals are a vital part of the eco-system and if you destroy just one plant or animal the whole eco-system suffers from it.

Living sustainably also stops CO2 escaping into the atmosphere. CO2 makes ice melt faster than it would on its own and that makes ocean levels rise which makes coastal areas flood. CO2 is also a poisonous gas.

It is also cheaper to live sustainably, because you would grow most of your food, not buy it. you would also reuse more and use things until they wore out, not until you wanted something new.

My last reason on why it is better to live sustainably is because it is better for your health. if you grow your own food using sustainable fertilizers then it will have more nutrients than bought food which is grown using artificial pest controls and fertilizers.

Those are my reasons on why it is better to live sustainably.

Supply and demand

In economics we are learning about Supply and demand. This is a graph about supply and demand, the producer of the goods will want to sell the goods for as high a price as possible however the consumer will want to buy the product for as low a price as possible. the point or price where both the supplyer and consumer are happy is called the equilibrium point.

Eco homes

Imaging being able to live in a completely eco-friendly house like this one here:
Solar heating systems, sustainable resources, it would be wonderful but how can you???
Here are some points you should take into consideration:
  • If you have a stone floor you won't need air-con because the stone absorbs the heat during the day and releases it during the night.
  • Use locally sourced products where possible as it saves transportation.
  • Try to avoid cement because even though it soaks up carbon from the atmosphere it releases more carbon when it is being made than it will ever soak up.

Limestone, Uranium and the Matai islands

In class because we are studying sustainability MrWoody has "discovered" a group of islands of the coast of Raglan and named them the Matai islands (which I don't understand as the islands are not in, or in the area surrounding, Matai bay - they are in Raglan). Each island has two natural resources and on our classes island we have Limestone and Uranium if you know anything we could do with them please comment here
