1Environmental Issues in Latin America SS6G2a. Explain the major environmental concerns of Latin America regarding the issues of air pollution in Mexico City, Mexico, rainforest destruction in Brazil, and oil-related pollution in Venezuela
2Mexico City air pollution Problem: 1 of the world’s worst areas of air pollutionCauses:crowded city – older cars, factoriesCity is built in bowl-shaped crater of extinct volcanothin air because of high elevation – air pollution gets trapped. Sun + dirty air = smogSolutions:Drivers leave cars at home 1 day/weekCar inspections and repairsFactories closed on days of bad pollutionImprove fuelsIncrease cars that burn less exhaust
31. How does geography play a role in Mexico City’s air pollution problem? 2. What are the main sources of air pollution in Mexico City? 3. How is the government trying to reduce air pollution? 4. Which solution is hardest for businesses?
4Brazil Rainforest Destruction More than ½ of Brazil is covered by rainforestHome to 40,000 types of plants and 1000s of animalsValuable:Medicines are made from plantsProducts – brazil nuts, cocoa, rubber20% of oxygen is produced by Brazilian rainforestsIndigenous people live in rainforest
5Problem: threatened by human activity Animals, plants, and people threatened with extinctionSelling timber – deforestation (then grow crops like soybeans/cattle on bare land)200,000 acres lostSolution: laws control number of trees that can be cut BUT… not much money spent on enforcing laws
65. What problems are associated with deforestation. 6 5. What problems are associated with deforestation? 6. Why does deforestation increase when the value of crops and cattle goes up? 7. What is the main crop grown in deforested areas? 8. What does the world get 20% of from the rainforest?
7Use graph on p. 18 of CRCT Test Prep and answer q. 17-20
8Venezuela oil-related pollution Venezuela is 1 of the largest producers of oil and natural gas in the world$$$ from oil sales accounts for ½ the government fundsCaribbean Sea has become polluted with oil from spillsVenezuela produces high levels of carbon dioxide from burning fossil fuels – causes breathing problems for kids and elderly and global warmingLake Maracaibo is sinking 3 inches/year due to oil extraction – dike had to be built to keep the lake from flooding
99. What problems are caused by oil production in Venezuela. 10 9. What problems are caused by oil production in Venezuela? 10. Why doesn’t the government want to stop oil production? 11. Whose breathing is affected most by too much carbon dioxide? 12. What does too much carbon dioxide cause?
