Environmental Issues in Latin America SS6G2 The student will discuss environmental issues in Latin America a. Explain the major environmental concerns of Latin America regarding the issues of air pollution in Mexico City, Mexico, the destruction of the rain forest in Brazil, and oil-related pollution in Venezuela

Mexico City, Mexico

capital of Mexico capital of Mexico population over 19 million people population over 19 million people Mexico’s largest city Mexico’s largest city built by the Spanish after they destroyed the original city of Tenochtitlán in Lake Texcoco built by the Spanish after they destroyed the original city of Tenochtitlán in Lake Texcoco located in the Valley of Mexico, surrounded by Sierra Madre mountains located in the Valley of Mexico, surrounded by Sierra Madre mountains

Air Pollution Over Mexico City

Causes population & location contribute to air pollution problem population & location contribute to air pollution problem emissions from factories and automobiles. emissions from factories and automobiles. Wind not strong enough to blow pollution over the mountains, bowl effect Wind not strong enough to blow pollution over the mountains, bowl effect high elevation--less oxygen so fuels don’t fully burn high elevation--less oxygen so fuels don’t fully burn

Surrounded by Sierra Madre mountains

Results of air pollution Pollutants harm eyes, lungs, and the heart. Pollutants harm eyes, lungs, and the heart. creates acid rain creates acid rain

Solutions program limiting how often you can drive your car, promotes public transportation program limiting how often you can drive your car, promotes public transportation testing buses that run on cleaner- burning fuels testing buses that run on cleaner- burning fuels strict inspections of emissions systems on cars strict inspections of emissions systems on cars changing the kind of fuel cars and factories use changing the kind of fuel cars and factories use workshops to teach people about the environment workshops to teach people about the environment

Amazon Rainforest

Destruction of the Amazon Rainforest Before… After… “slash and burn” farming

cattle ranching logging

Results of Deforestation Plants & animals are losing their homes; many are endangered, and some are becoming extinct. Plants & animals are losing their homes; many are endangered, and some are becoming extinct. Loss of trees increases carbon dioxide, a gas that contributes to global warming.

Venezuela

Oil-Related Pollution in Venezuela Oil provides about 50% of government revenue. Oil provides about 50% of government revenue. Oil production has boosted economy, turning the once poor country of Ecuador into one of Latin America’s richest countries Oil production has boosted economy, turning the once poor country of Ecuador into one of Latin America’s richest countries

Oil-related pollution in Venezuela

Causes Oil is the country’s main source of income, so people continue to produce, sell, and burn oil, creating more oil pollution. Oil is the country’s main source of income, so people continue to produce, sell, and burn oil, creating more oil pollution. Occasional oil spills Occasional oil spills

Oil-related pollution in Venezuela

Results creates toxic wastes creates toxic wastes air pollution air pollution occasional oil spillage, seeps into water sources occasional oil spillage, seeps into water sources streams and rivers polluted, hurts fishing industry and shut down tourist resorts streams and rivers polluted, hurts fishing industry and shut down tourist resorts health problems (cancer, skin problems, breathing problems, and digestive tract problems) health problems (cancer, skin problems, breathing problems, and digestive tract problems)

Solutions… People are becoming aware that the cost in the long term may be too great. People are becoming aware that the cost in the long term may be too great. Groups are calling for renewable energy sources and the clean-up and prevention of pollution. Groups are calling for renewable energy sources and the clean-up and prevention of pollution.
