Question:We consider Air, sunlight, water etc as a renewable natural resource. But with the increasing scarcity of water especially Drinking Water, do you still think Fresh Water as a non-exhaustible natural resource?

Answers:Here is Michigan it is nearly inexhaustible. Four Great Lakes, 11000+ inland lakes (35000+ bodies of water), many rivers and streams. That said, most of the world has a short supply of water.

Question:I need a two page essay on explaining why air isn't a renewable resource. So, i need a lot of RELIABLE info . thanks!!!

Answers:Air is a combination of several different gasses including nitrogen, oxygen, carbon dioxide, and water vapor...it is difficult to extract the gasses...air doesn't burn either...the oxygen in the air supplies the fuel for combustion, but when the oxygen is exhausted the fire goes out. However, when air moves to become wind it then becomes a renewable resource.

Question:if you could answer any of these questions it would help me so. these are 7th grade questions that need to be answered in 7th grade terms. the help given would allow me to pass this year and go to 8th grade. 1.the ____ rock is the layer beneath the shale where petroleum and natural gas accumulate. 2.any material resources not used as fossil fuels or as sources of metals are nonmetallic ___. 3.ice like substances called methane ____ may provide tremendous reserves of methane. 4.____ energy is derived from burning wood alcohol and garbage. 5. a(n) ___ is a deposit of minerals that is large enough to be mined at a profit. 6.inexhaustible and renewable resources are currently used less than ____ resources. 7.radon is a source of ___air pollution. if you have the answer to any of these please say witch q and the answer. all if any answers would be great.

Answers:1.hard 2. compounds 3. elements 4. Chemical 5. 6. exhaustible 7. radioactive gas

Question:Workable energy resource requirements, Independent of being Renewable: 1)Energy available 24 hours a day, 7 days a week, and 365 days a year. 2)At retail level directly compete with energy resources for today s activity - if not, sellable spin-off benefits to subsidize the cost. 3)Transportable 4)Technology available. 5)No more environmentally harmful than competing energy resources. 6)Supplies close enough to consumer that distribution losses due to capacity doesn't become an issue. 7)Politicians that back any solution be able to explain it to their constituents. The area below the question wasn't answering the question, but the breath of the question. I ve heard you are brilliantly creative. Economically there is at least 1 item more disastrous than investing in renewable energy infrastructure, not having a replacement for fossil fuel. I don't wish to taint your creativity with my solution. The governments have tryed thinking small with little addition to supply. I've gone the opposite route to change the economics of Renewable Energy. Please be as creative as the person was that during WW II came up with running the exhaust through aircraft feul tanks to mitigate possibily of explosition when shot.

Answers:To answer your primary question, it just needs to be less expensive than fossil fuels...oil in particular. 1. Very few "direct" renewable sources are available non-stop. A few would be tidal power, geothermal power and hydroelectric power. There are many "indirect" sources, such as biofuels (ethanol, biodiesel, methane) which are the process of extracting energy from materials. 2. Nothing is really practical (at this point) to compete. Oil is still too cheap. 3. Storage either in liquid fuel form or conversion to electricity offers the two easiest ways to move large amounts of energy. 4. There's many viable technologies available today, but they are under continuous refinement to make them better, more efficient, less costy, and ultimately, more competitive 5. This one is always fun. Wind and hydroelectric don't pollute, but one is blamed for killing migratory birds and the other is hated for destroying habitats surrounding rivers. Both offer the most promise as the next best source of energy compared to fossil fuels. 6. Well, this depends on whether the consumer is in an energy rich or energy poor area. If you live in an area where there's ample sun, good wind, and/or rivers you can dam up, then you're living close to where you can produce it. If you can't produce enough energy from the sources immediately available to you, then you will either need to conserve more or import it. 7. Politicians are likely only going to back solutions that prove to be overwhelmingly beneficial to their constituents. You will get corn belt pols that back ethanol for the obvious positive economic impact that it will have on their areas. Likewise, wind in areas that it could prove beneficial. There is no one magic bullet for every energy need, that needs to be understood. Some sources will win over others, based on the application and its availability. But until oil gets more expensive (like over $100 per barrel) then most alternative sources just simply can't economically compete with today's renewable harnessing technology.

GCSEPod Biology - Humans and the Environment: Negative Impacts :**This is a short sample from GCSEPod Biology - Humans and the Environment: Negative Impacts. The full title is 30 minutes long and includes 6 Chapters. ** We humans are just one of the many different organisms that live on our planet. Unfortunately, our success and rapid population growth have had many negative impacts on the environment. This title starts off by looking at how living organisms are able to interact to live successfully alongside one another in their habitats, and it finishes by looking at how humans have upset this delicate balance. We'll discuss the way organisms compete for resources, and why it's important for them to adapt for survival. Then we'll look at the important relationships between organisms, such as that between predators and their prey. This title also explains how scientists study populations of plants and animals, and discusses the problems associated with the rise of human populations, such as pollution and the exhaustion of resources.
