Presentation :

Natural resources are naturally occurring materials that form our Earth. These materials include air, water, soils, rocks, timber and plants. The Earth is the foundation of all life, so taking care of the Earth and its resources should be a responsibility shared by all. All resources are interconnected, so a deficiency in one area puts pressure on all others.
Our basic needs of air, water, food and ****ter are supplied by these resources. The environment is fragile. If just one of these four basic needs is removed from a habitat, humans, animals and plants suffer. As earth’s population increases, demand on these resources increases and thus their quantity is diminishing.
Some resources are renewable like the sun, but many such as petroleum upon which we rely heavily for energy, are non-renewable or finite. Once these finite resources are consumed, there will no more supplies. Most of this resource use stems from people and industries in developed countries like New Zealand, Australia, the United States and Europe.
With resource use comes waste. Excess food, packaging, products and unwanted materials end up as waste in our landfills. In order to sustain our quality of life, we must conserve our resources through waste reduction, reuse and recycling.
