Natural resourcesNatural resources refer to anything that

is taken from nature and that can be used by humans in their daily lives.

There are tow types of natural resources :

-Renewable: wood,food…etc.-Non-renewable: Carbon, natural gas…etc.

Energy resources

Energy is a basic resource for humanity, because of this there are a variety of energy sources. In order for an energy source to be useful, it must be easy to obtain, cost-effective and provide energy in forms that can be transported and used.

The energy sources can be classified for their use: conventional or alternative. Or they can be classified in renewable or non-renewable ( depending if they use renewable or non-renewable natural resources).

RENEWABLE

Renewable energy is the energy which is generated from natural sources such as sun, wind, rain, tides and can be generated again and again as and when required. They are available in plenty and by far most the cleanest sources of energy available on this planet. For example: energy that we receive from the sun can be used to generate electricity. Similarly, energy from wind, geothermal, biomass from plants, tides can be used to fulfill our daily energy demands.

NON-RENEWABLE

A non-renewable resource is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas.

Fossil fuels(such as coal, pretoleum and natural gas), and certain aquifers are all non-renewables natural resources.

Human activity

Human activities are responsible for most of the loss in biodiversity throughout the world. With an increasing population, we are consuming more and more natural resources.. We do this by driving more, using more energy in our homes, and buying many more products than we need.

Mainly environmental problems

Global warming

Greenhouse effect

What are drugs?

A drug is any chemical substance that affects the way your body works. Alcohol, caffeine, aspirin and nicotine are all drugs.

A drug must be able to pass from your body into your brain. Once inside your brain, drugs can change the messages your brain cells are sending to each other, and to the rest of your body.

They do this by interfering with your brain's own chemical signals: neurotransmitters that transfer signals across synapses.

What are the consequences of drugs

use?The impact of addiction can be far reaching.

Cardiovascular disease, stroke, cancer, hepatitis, and lung disease can all be affected by drug abuse. Some of these effects occur when drugs are used at high doses or after prolonged use, however, some may occur after just one use.

The drugs also has: kidney, liver, neurological, hormonal … effects.

Types of drugs

Stimulants: These drugs elevate mood; heighten alertness, increase energy and feelings of well being. For example: ecstasy, cocaine, methamphetamine, amphetamines.

Depressants:These form a major group among the various types of illegal drugs. Depressants simply depress the nervous system. For example: marijuana, barbiturates, tranquilizers, heroin, morphine and codeine.

Inhalants:Inhalants are commonly found most in workplaces or homes. For example: markers, glues…etc.

Hallucinogens:Hallucinogens cause alternations in thought, mood or perception. Hallucinogens have a very rich history and have been used by various cultures around the world to induce mystical or religious experiences. For example: Ketamine, madrake…etc.

What can we do to prevent the use of

drugs?These are some examples of how to prevent

drugs use in young people: -Participating in sports activities. -Attending career fairs. -Presentations from colleges and universities. -Opportunities for leadership. -Active involvement of parents.

Is there peer pressure to use drugs?

A common motive for first time drug and alcohol use is peer pressure. Membership of a social group that supports drug or alcohol use encourages people to keep on using these substances. It is also the case that belonging to a group that supports recovery can help the individual escape drug abuse. Peer pressure is an important factor when it comes to using alcohol and drugs.Research confirms that most adolescent drug users are introduced in this behavior by friends.
