Deforestation and Habitat Loss

What can you do about tourists use of natural resources?

Tourists pollute waterways and oceans, they damage the environment

What we can do about it: By governments putting restrictions on holiday resorts and developers, they can prevent resorts being built on wildlife habitats, and also close down or limit the size of resorts already built on wildlife habitats.

  • There must be no pollution into waterways and oceans.
  • Garbage and sewage must be collected and recycled as much as possible.
  • Tourist movements into natural areas must be limited so the numbers don't do any damage to the environment.
  • Building must blend into the natural environment.
  • There must be no illegal deforestation (eg, cutting down rainforests to build a golf course).
  • New resorts and gardens must not put too great a demand on water and other natural resources.

we could put more bins out on the steets.

They use our food, water and land.

Science working models for class 9?

go for hydro power plant

i made this model when i was in ninth

this is very easy

on a thermacol make two houses or hut one road and most importantantly one dam

buy one small motor this is easily available in markets

it will cost you Rs 50

it will hawe a shaft

attach turbine to it made of silver foil which we use for food packaging

take two bulbs use it as light of the huts

make two street lights near roads

while showing its working use battery or cells to light them

you can explain it as when turbine rotates it produces electricity which we ase for domestic or industrial purpuse

i know it will be hard for you to make it without seeing

but i will try to find out a photo graph of my model

other is solar energy in this olso u have to make huts roads and all

as solar cells r very costly u can make them using a mirror

u can also make model on topic circulatary system

make a big diagram of heart and use to pipes and pumps

add blue color in water to show impure blood and red color to show pure blood

What are the advantages of a free market economy?

The advantages of a market economy can be summarized as:

-Buyers are free to buy any commodity which they like and in whatever amounts. The producer can also produce whichever product they want to and also increase the capacity of any individual commodity depending upon the forces of the market. Producers are free to undertake the risks and rewards associated with increase in production. There is no state intervention in the functioning of the forces of the market. -The biggest advantage that a market-oriented economy enjoys is the determination of a unique price determined by the demand and supply in absence of any monopolistic or oligopolistic influences. The decision of what to produce, for whom to produce and in what quantities is taken by the market forces and not determined by the state. -The role of the state is limited to ensuring proper transparency in the prices charged by the sellers of the concerned commodity. Prices also have the function to allocate and distribute a country's resources. -In a "perfect world", free market leads to complete efficiency bringing about the optimal distribution of a country's resources. This would only happen in a state of equilibrium or when demand equals supply and there is a unique price for every commodity in question. But in a practical world which is imperfect by nature, prices are never at equilibrium and very volatile depending upon the vagaries of the market forces. This generally harms people living below the poverty line or those in the low income group. It is impossible for them to pay high prices in cases of demand shortage and thus the free market model is not a viable option in developing countries which has a large number of poor.

-Free market and liberalization with increased competition has increased unemployment levels and poverty in India and China with the growing divide between the rich and the poor. Growing at an average of 10% per year since 1978, increased levels of efficiency and prosperity have not percolated to the grassroots level. Developed economies such as the USA and Canada are also facing limited problems of poverty and unemployment as a result of total free market economy.

-Free market economies, although have been successful in developed economies, will not be so in developing countries and the only recourse for them is the model of the mixed economy or social market economy. The welfare role of the state is retained in a social market economy which cares for the poor. In cases where the poor countries are striving towards a free market economy, there should be certain segments controlled by the state but with prevalence of free enterprise such that efficiency is restored and the country moves towards economic prosperity. Free market economy under centralized political control is the most effective way for these countries
One advantage of the market economy is that the market provides incentives which help the people acquire very useful skills.

What is the advantage of free market economy?

Wikimedia Free Encyclopedia explains: A market economy(also called a free market economy or a free enterprise economy) is an economic system in which the production and distribution of goods and services take place through the mechanism of free markets guided by a free price system. In a market economy, businesses and consumers decide of their own volition what they will purchase and produce. Technically this means that the producer gets to decide what to produce, how much to produce, what to charge to customers for those goods, what to pay employees, etc., and not the government. These decisions in a free-market economy are influenced by the pressures of competition, supply, and demand. This is often contrasted with a planned economy, in which a central government decides what will be produced and in what quantities.

No pure market economy exists. Thus, almost all economies in the world today are mixed economies which combine varying degrees of market and command economy traits. For example, in the United States there are more market economy traits than in Western European countries.

The advantages of a free market economy are for example - supply and demand

A free market economy allows competition. Without competition, prices would be a lot higher. This is due to the fact that companies compete for more customers. A way to gain more customers is lower prices. This is the advantage over having a free market economy rather than a command economy (think communist). In a command economy, there is no one to compete against so you can charge as much as you want for your products. In a free market economy, you can only survive if you lower your prices. This is because consumers have a choice of what company to buy from. This is another advantage of the free market economy.

Birds
Electrical Engineering

Why can birds stand on overhead transmission lines without suffering any harm?

The short answer is they are not grounded. You can hang from a line also and not be harmed, but don't try it as if you do it wrong you can be severely hurt or killed. So what does "they are not grounded" mean? Electric current flows from high voltage to low voltage. The power line is high voltage. The earth, or ground, is low voltage. Anything in contact with the earth is also at the same low voltage. That is why there are insulators between the lines and the poles. The higher voltage the lines, the bigger the insulators. You can see this for yourself by looking at a high voltage tower versus a typical wooden power poll. When the bird lands on the line, it is only in contact with the line. There is no path to the lower voltage ground for the electrical current to flow thorugh. No current flow means no harm to the bird. People get into to trouble with power lines because they are almost always in contact with the pole or the ground when they, or something they are holding, touch the line, which means the current flows through them to the lower voltage. Note that the lower voltage does not have to be zero volts. It just has to be lower than the high voltage for the current to flow. It is not the voltage that kills you. It is the combination of voltage and current. No current or low current, no harm. When you scoot your feet on the carpet on a dry day and touch the door knob, a spark jumps and you feel a small snap. Your skin is charged up to 10's of thousands of volts, but there is very little current flow, so no harm is done. Hope this helps.

Vaccinations

Why use vaccinations?

Vaccinations are important so that if you get that disease, your body will know how to fight it off and you won't suffer. Basically a vaccine is when they are putting the disease into your body but in a much weaker form of the disease so that every human body is capable of fighting it off quickly. This way your body knows how to fight it off and is prepared to fight it off if you get the real disease. This is why vaccinations are important for your body.
