Energy resources
We have to share these resources with all the others lifeforms on The Earth.
We divide natural resources into renewable and non-renewable. Renewable resources are the ones that will never run out (maybe!!). Resources such as trees, fish, oxygen, and fresh water are renewable resources as they can be continually reproduced. Fresh water from the Earth's recycling process, fresh air from the oxygen produced by plants and trees, and trees and fish which can reproduce themselves
We are destroying the cycle of reproduction of trees and fish by our habits. For example the number of fish extremely decreased after we began with massive worldwide fishing in 20th century. Forests are not destroyed only by massive logging but we destroy them also by regular “logging” of “x-mas trees”. Real wooden trees are still more popular than imitational and ecological trees. For how long?
Industrialization brings big progress and also big pollution!! When people think about air pollution, they usually think about smog, acid rain, and other forms of outdoor air pollution. But did you know that air pollution also could exist inside homes and other buildings? It can, and every year, chemical substances in the air within buildings affect the health of many people.
Renewable resources can become a non-renewable ones. How? Listen: Plants and Animals - When plant and animal species become extinct. Fresh water - When fresh groundwater gets used up and no rain falls, sometimes for years. More then 75% of underground water is non-renewable. From chemical spills is the nature so toxic that the water and surrounding soils are polluted for a lifetime. And think about population growth -70 million people are added to our planet every year. Trees - When a forest of trees is clear-cutted, it can change the soil and the climate of the ecosystem so new trees cannot grow, plants die, and animals lose their habitat and die or leave the area. A natural forest has a variety of trees, plants, and life forms. A natural forest creates climate. These ecosystems evolved over a very, very long period of time and through many geologic and climatic changes. Should humans, then, be allowed to buy whole ecosystems to destroy them for money? That is what happens when a forest is clear cutted.
Oxygen/Clean Air - When forests and plants (on land and in our oceans) are destroyed or die from acid rain and pollution, they can no longer absorb carbon dioxide from the air, and release oxygen into the atmosphere. When rivers are polluted by chemicals and erosion, oxygen is putted away from the water and living things die. Land/Soil - When land is overgrazed or the nutrients in the soil used up from improper farming practices, the soil cannot renew itself and plants and crops cannot grow. Crop rotation is one way to help maintain soil fertility. When natural vegetation is removed from land to clear it for construction projects, mining operations or farmland, the plants and trees are no longer there to absorb rainwater and protect the soil from wind. Erosion occurs and the soil is washed away or soil particles are blown away in the winds. Fish - When land is cleared of vegetation in watershed areas that drain into rivers, lakes, streams, estuaries, etc., soil erodes into the water and the silt smothers the fish and plant life. When pollutants drain into these waters, the toxins kill aquatic life and the pollutants can be carried through the water far distances. Biospheres of living things - When pollution destroys an area, like the devastating Exxon Valdez oil spill and the Chernobyl nuclear accident. Environmental disasters such as these affect whole biospheres and damage all living things for thousands of miles for many, many years. Nuclear contamination can last for longer than lifetimes.
Renewable sources are defined as: "capable of being replaced by natural ecological cycles or sound management practices" So humans need to think that the renewable sources are able to renew only in the right circumstances and within the laws of the balance of nature (allow the natural ecological cycles to remain natural, and "Don't mess with Mother Nature!") Not "Oh well, it's renewable so we can use as much as we want"
Not "It won't matter what we do with our toxic waste, just so we get rid of it"
Not "We can't convert our old factories toxic burning methods- it's too expensive."
Not "It's OK to log these forests - field surveys are not needed." "Renewable" resources become non-renewable due to mis-management by humans and due to pollution of the environment by humans.
HUMANS ARE RENEWABLE - BUT ONLY IN THE RIGHT CIRCUMSTANCES AND WITHIN THE LAWS OF THE BALANCE OF NATURE Such things as fossil fuels (oil, coal, gas) and minerals cannot be reproduced and therefore can be used up. These are called non-renewable resources. Humans are using up natural resources at a great rate and at a great cost to the health of the natural environment and life on Earth.
Fossils are remains or impressions of organisms of past geologic ages. Fossil fuels were formed from organic matter (plants and animals) which were buried millions of years ago. In time, the pressure of the massive weight of rock and mud that covered the organic matter created heat, which changed this matter over a period of several hundred million years to oil (remains of ancient marine organisms), coal (remains of ancient swamps and forests), and natural gas. We use these energy sources as fuel; therefore, they are called fossil fuels. How can natural resources affect our environment unnaturally?
It is not the natural resources by themselves that harm the Earth's environment - it is what humans do with the natural resources that cause the problems to the environment and to the health of living things, including other human beings. The burning of fossil fuels in factories to make products and power, and the fuels used by trucks, automobiles and jet planes have caused acid rain and a great increase in carbon dioxide and pollution in the atmosphere. And forests have been destroyed which used to absorb carbon dioxide. Carbon dioxide traps heat in our lower atmosphere. Scientists believe that human activities such as these have led to global warming.
IS THERE ANY SOLUTION ON HOW TO GET RID OF THOSE PROBLEMS?? YES!!!! Scientists are working very hard on developing new ways to use clean energy sources which come from renewable resources - like wind power and direct solar energy from the sun. Approximately every 40 minutes the sun sends as much energy to Earth as all the people on Earth use in a year! But, we have to get industry to make more products that use the safe environmentally-friendly energy, like solar-powered vehicles, and at a price people can afford. Other technologies, such as fuel cells, are under development to provide energy sources that minimally harm the environment. People need to change their thinking and refuse products that damage the environment.
SOLAR POWER, that's obvious, but the energy in coal originally came chemical energy that was stored in plants millions of years ago.The same goes for Wind and Wave power. Waves occur because of winds, and winds blow because the Sun warms our atmosphere. Warm air tends to rise, and winds are due to other air moving in to replace it. Most power stations burn coal, oil or natural gas to run the generators. Others use uranium, or the flow of water. Electricity is sent around the country using high-voltage power lines. Nearly all of the power we use comes from large power stations, although some places such as isolated farms, or hospitals, have their own diesel generators. From the Sun too. Prehistoric plants stored the Sun's energy in their leaves, and when they died and eventually formed coal seams, that energy was still there. So when we burn coal (or any fossil fuel), we're releasing Nuclear power is generated using Uranium, which is a metal mined in various parts of the world. The first large-scale nuclear power station opened at Calder Hall in Cumbria, England, in 1956. Some military ships and submarines have nuclear power plants for engines. Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you'd get from burning fossil fuels. In Britain, nuclear power stations are built on the coast, and use seawater for cooling the steam ready to be pumped round again. This means that they don't have the huge "cooling towers" seen at other power stations.If something does go wrong in a really big way, much of the world could be affected - some radioactive dust (called "fallout") from the Chernobyl accident landed in the UK. With AGR reactors (the most common type in Britain) there are additional safety systems, such as flooding the reactor with nitrogen and/or water to absorb all the neutrons - although the water option means that reactor can never be restarted.
Your body has natural resources also!!
All parts of your body work together to keep you alive and healthy. What happens if you get an infection in the natural resources of your body? You get sick and don't feel well. The infection is toxic pollution It harms your natural resources. It harms your body's environment. Then you need a special investigator to find out what is making you sick and to help you get well. Your body's special investigator is your doctor. The doctor can tell you what medicine to take to get rid of the toxic infection, so your body can get healthy again.
