  2. Guide -Natural resources: -Energyresources. -Humanactivity. -Environmentalproblems. -Drugs: -What are drugs. -Effects of drugs. -Types of drugs.

  3. Natural resources • Natural resourcesrefertoanythingthatistakenfromnature and that can beusedbyhumans in theirdailylives. • There are towtypes of natural resources : -Renewable: wood,food…etc. -Non-renewable: Carbon, natural gas…etc.

  4. Energyresources • Energyis a basicresourceforhumanity, because of thisthere are a variety of energysources. In orderforanenergysourcetobeuseful, itmustbeeasytoobtain, cost-effective and provideenergy in formsthat can betransported and used. • Theenergysources can beclassifiedfortheir use: conventionaloralternative. Orthey can beclassified in renewableor non-renewable ( dependingifthey use renewableor non-renewable natural resources).

  5. RENEWABLE • Renewableenergyistheenergywhichisgeneratedfrom natural sourcessuch as sun, wind, rain, tides and can be generatedagain and again as and whenrequired. They are available in plenty and byfarmostthecleanestsources of energyavailableonthisplanet. Forexample: energythatwereceivefromthesun can be usedtogenerateelectricity. Similarly, energyfromwind, geothermal, biomassfromplants, tides can be usedtofulfillourdailyenergydemands.

  6. NON-RENEWABLE • A non-renewableresourceis a resourcethatdoesnotrenewitself at a sufficientrateforsustainableeconomicextraction in meaningful human time-frames. Anexampleiscarbon-based, organically-derived fuel. The original organic material, withtheaid of heat and pressure, becomes a fuel such as oilor gas. • Fossilfuels(such as coal, pretoleum and natural gas), and certainaquifers are all non-renewables natural resources.

  7. Humanactivity • Human activities are responsibleformost of theloss in biodiversitythroughouttheworld. Withanincreasingpopulation, we are consuming more and more natural resources.. We do thisbydriving more, using more energy in ourhomes, and buyingmany more productsthanweneed.

  12. 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.

  13. 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.

  14. 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.

  15. 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.

  16. What can we do to prevent the use of drugs? • These are someexamples of howtopreventdrugs use in youngpeople: • -Participating in sportsactivities. • -Attendingcareerfairs. • -Presentations from colleges and universities. • -Opportunitiesforleadership. • -Active involvement of parents.

  17. 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.
