Transcript of Natural Resources
Our planet is full of the resources we need to survive and create, but with the fast growing population and industries we could find ourselves with a shortage. A shortage of energy, food and clean water.
Natural & Renewable
Renewable resources are everywhere and we will soon need to tap them more and more.
Bio Mass Energy
Compressed Natural Gas
Forest & Trees
Wind energy is converting the force of the wind to make electricity with wind turbines, mechanical movement with wind mills and sails to propel ships.
Natural yet non-renewable
Non-renewable resources are a quick solution but we are running out, soon alternative energy sources will need to be found.
These minerals all refer to metals such as gold, copper and iron ore which all have uses. gold is made into jewelry and inlaid in watches, copper was used to line older ships' hulls and is now used in our currency and iron ore is heated and turned into a purer form, steel or some millionaire's suit.
This category includes salt, stone, clay and sand. Salt is often seen on the dinner table or on an ingredients list, stone or rocks are seen nearly every day, either lying around or for decoration, clay is turned into pots and bowls and beautiful works of art and sand is used to make glass and sand-sculptures.
Oil can be found underground in large or small deposits and is used to power cars, boats, planes and some forms of heating and cooling. When drilling for oil, spills can occur and will devastate the surrounding environment.
Coal is a black or dark brown rock mostly made up of ancient compressed plant material. Coal is highly combustible and a "practical" way to extract thermal energy from the earth and is used in factories and power plants to power the facilities. In some countries the working conditions for harvesting coal are extremely poor, the workers are not receiving good equipment and getting unfair wages. Coal, when burned, releases harmful carbon gases into the air.
Natural gas is highly combustible and occurs underground, often near large oil deposits, and is made up of methane and other hydrocarbons. It is used for powering some street lights and heats many homes.
Natural resources by: S.Saucedo & M.Ram
Solar energy in energy derived from the rays of the sun, people often use it to power their homes while some larger corporations use it to power most of all of the industry. This method of harvesting power only works where there are constant amounts of sun light.
Hydroelectric power is harvested by channeling water under pressure through a small space with a generator, turning it to create electricity. The most common example of this is dams.
Radiant energy is heat that travels over waves or particles, such as is seen in x-rays, lighting and the heat given of by a camp fire.
Geothermal energy is energy derived from the earth and the steam or hot water is used to turn a turbine which generates electricity.
Bio Mass Energy
Bio mass refers to fuel harvested from plant matter, trees shavings and other natural waste residues. To gather energy from the matter it is burned and the heat is then used to power the equipment designed for bio mass energy.
Compressed natural gas
Compressed natural gas is drawn from wells and can be found with oil. Compressed natural gas is most commonly used as an alternative to diesel and gasoline.
Nuclear energy is created when atoms are super heated and split apart, it also releases energy in the form of heat, this heat is used to bring water to a boiling point and create steam, the steam then turns a turbine creating electricity.
Wave power is the harnessing of the oceans waves to generate electricity. The electricity generated from the ocean could soon be used to power your everyday life.
Similar to Wave power, Tidal power uses the ocean to generate energy, mainly electricity. Tidal power however uses the movement of the tide to generate power.
Forests & Trees
Trees, when cut down, can be used to generate thermal energy while being burned and wood chips can be used to make bio mass energy. One of the most common forms of tree resources is paper. We use paper almost
Water power is energy that is taken from the motion or weight and used to drive machinery, such as a water mill.
Hydrogen fuel uses electrochemical cells, or combustion in internal engines, to power cars and electrical devices.
World resources, consumption, and trading
carrying capacity of the Earth
Carrying capacity of the earth is the amount of people the earth is able to sustain. Some scientists believe that the carrying capacity of the earth is between 9 to 10 billion produce due to the amount of food able to be produced, the amount of freshwater and the continuous growth of the human population. There is an estimated amount of around 6 to 7 billion people on earth.
According to BBC these are the top 7 recycling countries:
Austria 49.7 %
U.S.A 31.5% (What are we doing down here!?)
Most other countries are recycling plastic, glass and clothing, turning it into new products and are making a lot of money off this industry.
When YOU recycle...
YOU are giving off less waste...
YOU are conserving our resources...
YOU are reducing pollution...
YOU are giving off less greenhouse gases...
YOU are protecting the wildlife...
YOU are making the world a better place...
The natural gas consumption throughout the world
Coal consumption of the globe
Our oil consumption
every day and when we aren't writing on it we are probably using a paper product.
WHY DO WE PRODUCE THINGS WE CAN'T REUSE?
To answer the question 'Why do we produce things we can't reuse?' we first must answer the question 'What is our human nature?' Our human nature is to find the easiest, simplest and cheapest way to do something, this effects our lives everyday, whether we like it or not. Now how do you think this effects the way we produce our products? Simple, we find the easiest, simplest and/or cheapest ways to do it! So to answer the question 'Why do we produce things we can't reuse?' we simply have to apply human nature and there's our answer! For some corporations create things we can't reuse simply because it's cheaper and others either don't care or don't want to go through the hassle of changing the way they do things.
Recycling products helps keep waste levels down and lowers the demand for raw materials. When the demand for raw materials is low more of a product will made with recycled materials.
When fewer raw materials are needed it lessens the demand for coal and oil to be burned, emitting less greenhouse gases.
The more people recycle, the less greenhouse gases will be given off and pollution will lessen.
Fewer Natural resources will be excavated and used to make new products.
When you were resources are excavated the wildlife and its habitat, which would other wise be taken apart, is preserved.
How can we better use it?
How should we better use our non-renewable resources? We should find cleaner ways to burn coal, oil and natural gas. We should become more aware of the small things like turning the lights off when leaving the room, not idling cars for long periods of time and not wasting money on unneeded "necessities." We should recycle to conserve what we have and lower of the demand for plastic, paper and metals.
Our Big "Carbon" Foot
Everything we buy, use and throw away has a profound impact on the environment. We do all these things without a second thought, we don't realize how big of an impact one person can make. Our carbon footprint is the amount of carbon emission given off due to the use of fossil fuels. The more we buy, the more they make.
Carbon credit is a way to lower carbon emissions on a global scale. One credit is earned when a corporation, for example, has made at least one ton less carbon gases then was originally estimated. One credit is awarded per ton. Carbon credits are used in global trade and some believe it to be the immediate solution to carbon emissions.
"where's my water?"
Water, cool, clear and vital to the survival every living creature. We have always had a dependency on water and we have always had plenty. So what changed? Well, how about our overuse of coal, oil and other pollutants? And are growing carbon footprint and making landfills? Can't we just go outside and get some? No, we have contaminated it. It is our fault water is not as clean as it used to be.
Where is the usable water?
A lot of drinking water comes from either rivers and lakes (surface water) or wells (groundwater). The water taken from these places is then put through a cleaning process and sent to you threw pipes.
Where are we making more usable water?
Since we can know longer drink water straight from the source we must put it through a cleaning process. The water is taken and through a plant that filters out the particles and parasites.
How are we destroying our water?
Rain forests are amazing places, full of life rarely seen anywhere else. They are also our major oxygen producers. But they are shrinking due to over harvesting for timber and population. Most of the rain forests are located around the equator but those are not the only oxygen producers, there are also the huge evergreen forests.
