1 Environmental Concerns F. Ciangura

2 What is happening to some animals?  Some animals have become EXTINCT. Dinosaurs F. Ciangura

3  This means that all the animals of that particular species have died out! Some have died out naturally, like the dinosaurs and mammoths Mammoths F. Ciangura

4  Others have become extinct because of mankind. Humans have hunted and killed all of these animals.  This means that these animals can never be seen living again!! Dodo – was killed for food F. Ciangura

5  Some animals are ENDANGERED.  This means that these animals are in danger of becoming extinct! Their number is so small, that if we do not stop killing them and we protect them, these may all die out one day. F. Ciangura

6 Pictures of endangered animals Elephants Bighorn Sheep Californian condor F. Ciangura

7 Blue Whale Chinese River Dolphin Cuban Crocodile F. Ciangura

8 Orangutans Gorillas F. Ciangura

9 Fin Whale Leopard Tiger Red wolf Flat back turtle Leopard F. Ciangura

10  Environmental organisations have come out with a RED LIST, a list that mentions the endangered animals of our times.  ‘CITES’ stands for the ‘Convention on International Trade in Endangered Species of Wild Flora and Fauna’, (Flora = plant, Fauna = animal).  It is a United Nations administered Treaty, also known as the "Washington Treaty", which was set up in 1975 to control the international trade in wild flora and fauna in order to protect against over exploitation through commercial trade. Aye-aye Look up this list on the Internet by clicking on this site To learn about environmental groups that work to protect wildlife click on F. Ciangura

12 What about elephants?  Elephants have been hunted and killed to sell their tusks. These tusks are made of ivory…. A very expensive material that is used to make ornaments, jewellery and statues! F. Ciangura

13 Elephants killed to cut off the tusks that are made of ivory. Tusks are then sold to produce statues and other ornaments IVORY F. Ciangura

14 What is being done to protect elephants?  Conservationist groups like WWF (World Wide Fund) help to raise awareness and money  Ban of ivory in 1990 (it is illegal to buy and sell it)  Educate young children in Kenya to protect elephants F. Ciangura

15  Today, the number of elephants is increasing, but people are still working hard to keep their number stable.  An elephant takes 21 months to reproduce and the baby cannot have an independent life until it is 10 years old! F. Ciangura

16 What about the pollution in the world? F. Ciangura

17 Renewable and Non-Renewable Resources  Renewable means to use again. RENEWABLE RESOURCES are things found in nature that are used to produce energy, heat and electricity and can be used over and over again.  Non-Renewable means cannot be use again. NON- RENEWABLE RESOURCES are things found in nature that are used to produce energy, heat and electricity and can only be used once. F. Ciangura

18 NON- Renewable energy resources CAN BE USED ONLY ONCE  Wood  Coal  Natural Gas  Oil  Uranium (Nuclear Energy) F. Ciangura

19 Oil rig Nuclear power station Wood Coal miner CAN BE USED ONLY ONCE F. Ciangura

20 Do Non-Renewable energy resources cause problems?  Yes, they cause a lot of pollution.  Coal, oil and gas are fossil fuels and when burnt they give out a lot of smoke causing diseases like asthma.  Carbon Dioxide which is very bad because it traps heat around the earth causing world temperatures to rise (Global warming).  Acid rain can also happen. The explosion at the Chernobyl nuclear power station on Saturday, April 26, 1986, was undoubtedly the world's greatest nuclear accident. While only about 3% of the reactor core escaped, it was enough to kill those near it, and damage food and crops worldwide F. Ciangura

21 Global Warming CARBON DIOXIDE in the air traps heat around the world, causing a rise in temperatures F. Ciangura

22 Effects of acid rain SULPHUR DIOXIDE+ rain F. Ciangura

23 Kyoto Protocol Countries signing this Protocol agree to reduce the level of Carbon Dioxide by at least five per cent below the 1990 level by F. Ciangura

24 Renewable energy resources CAN BE USED OVER AND OVER AGAIN  Wind  Tide  Wave  Geothermal  Solar  Water F. Ciangura

25 Tidal energy Dams used for Water energy – HEP Wave energy Wind turbines Geothermal PowerStation Solar panels CAN BE USED OVER AND OVER AGAIN F. Ciangura

26 Do Renewable energy resources cause problems?  No, they do not pollute. They do not produce smoke!!  They are a bit expensive to built at first.  They do not finish…  Example, if you buy a solar water heater, you can get hot water forever without having to pay extra electricity bills and without having to burn oil at power stations to produce electricity. F. Ciangura

27 Oil and the environment On the evening of July 6, 1988, a fire broke out the off-shore oil and gas platform Piper Alpha located in the North Sea. The fire was uncontrollable and evacuation plans inadequate. 167 men died and 62 men were pulled from the sea. F. Ciangura

28  Images From the Exxon Valdez Spill, March,24 th,  /exxon/exxon.html F. Ciangura

29 Where do we get oil? 1. Exploration of new oilfields either under ground or under sea. 2. Oil is reached by drilling into the ground or under the sea. 3. Oil is moved by pipeline or oil tanker to an oil refinery. 4. Oil is stored until it is needed. 5. At the refinery the oil is turned into petrol for cars or refined for use in power stations. F. Ciangura

30 1. Exploration 2. Drilling 3.Transport by pipelines or tankers 4. Storage 5. Refinery F. Ciangura

31 Exploitation of oil harms the environment 3. Visual pollution – Pipelines and refineries are Eye-sores 5. Smell – smoke from refineries 4. Noise pollution – when drilling for oil 2. Water pollution – Oil spills 1. Air pollution – Smoke from refineries F. Ciangura

32 THE END F. Ciangura
