The document discusses several environmental issues including global warming, climate change, and ocean pollution. It outlines the various human activities that contribute to rising global temperatures such as burning fossil fuels and deforestation. These activities increase greenhouse gases in the atmosphere and disrupt the greenhouse effect. The document also discusses how ocean pollution from land runoff and plastic waste kills millions of seabirds, fish, and other marine life each year. Major oil spills devastate ocean ecosystems, such as the 1989 Exxon Valdez spill in Alaska which killed hundreds of thousands of animals. Solutions proposed include international agreements to limit greenhouse gases, reducing synthetic pollutants, stopping ocean dumping, and supporting environmental protection efforts.
2. Global Warming and causes of Global Warming
• Slowly, the ability of the earth’s atmosphere to absorb heat from the surface has increased and, with it, the temperature
of the atmosphere. This is known as global warming.
• Increase in the amount of greenhouse gasses in the atmosphere attributed mainly to human activity. Which is caused an
unbalanced in the process called the green house effect.
Causes
1. Burning fossil fuels
2. Cutting down trees
3. Burning forest
4. Factories Pollulaion
5. Coal
6. Oil
7. Natural Gases
8. Rising Sea levels
Acid Rain-Toxic Rain Caused
by Industrial Activities
Greenhouse Effect-Rise in the
earth’s temperature from greenhouse Gases
Ozone Layer—Layer of atmosphere
blocking UV radiation
Climate Change and Causes of Climate Change
• Climate change refers to general shifts in climate, including temperature, precipitation, winds,
and other factors.
• Factors are sun’s output, changes in the earth’s orbit and tilt, and volcanic activity etc.
Causes
1. Human Causes
2. Increase green house gasses(emulsion from buning fossils fuels-oil, coal etc)
3. Pollution, smog from factories.
4. Deforestation
5. Increasing Population (More people more CO2)
Solutions
Kyoto Protocol-International agreement on reducing
3. The Ocean, Ocean Pollution & Oil Spills
Quick Facts about the Ocean
Our Planet is made up of 70% water.
There Is 326,000,000,000,000,000,000 gallons (326 million trillion gallons of water on the earth
96% of water on the earth is ocean water
Fourteen billion pounds of garbage, mostly plastic, is dumped into the ocean every year
Quick Facts on Ocean Pollution
Over 80% of the pollution in the ocean is runoff from the Land
Almost 90% of all floating materials in the ocean are plastic
Marine debris, especially plastic, kills more than one million seabirds and 100,000 mammals and sea turtles every year
Dead Zones which are areas of oxygen deficient water were life ceases to exist, have increased drastically over the past decade
Exxon Valdez oil tanker spill dumped 11 million gallons in Prince William Sound, Alaska,
on March 24, 1989
Environment Effects of Exxon Spill
•250,000 Birds
•250 Bald Eagles
•2,800 Sea Otters
•300 Harbor Seals
•Thousands of fish, herring eggs, and crabs
•At least 22 Killer Whales
•Intertidal plants and animals
Environmentalists were outraged: Oil Spills
negatively effects marine animal life. Prevents
Natural selection. A Theory made famous by Charles
Darwin lead the theory on the evolution of plant and
animal life
Solutions to Oil Spills
•Monitoring full tankers via satellite
•Two escort vessels accompanying tankers
while they pass through the entire sound
•Specially trained marine pilots
•Double-hulled tankers
•Yearly drills held for spill scenarios
•New and improved skimming technologies
•More storage space for spilled oil
•More containment booms available
•Oil Pollution Act of 1990
4. Solutions To All These Problems
1. Unite As A community: Because of the global nature
of environmental problems, international agreements
are often used to address environmental issues. We
must stick to agreements like the Kyoto Protocol.
2. We Must Stop The most widespread form of ocean
pollution is the deliberate dumping of oil.
3. We must work to stop Synthetic products causing
major ozone depletion called chlorofluorocarbons (Cfc s)
