Sustainable Use of ResourcesUsing natural resources in a way that doesn’t deplete them Plant a tree for every one cut down Use biofuels Alternative energies
Acid Rain Causes: burning of fossil fuels and factories with smoke stacks release sulfur into the air making precipitation acidic.
Acid Rain Effects Destroys plant tissues Destroys aquatic ecosystems Destroys many statues
Acid Rain on pH scale
Affects of Acid Rain
Acid Rain Solutions Create laws that limit emissions from smoke stacks. Create laws that mandate (force) factory owners to use scrubbers on smoke stacks Use cleaner fuel sources
Most smoke stacks now have scrubbers!
Increase in the average temperature of the biosphereGlobal Climate Change Increase in the average temperature of the biosphere
The Evidence In the past 120 years the average global temperature has risen .5 degrees Celsius The 1990’s was the hottest decade on record
The Projections Computer models suggest that the average global temperatures will increase by 1 to 2 degrees Celsius by 2050.
The Cause of Climate ChangeIncreased amounts of CO2 that enters the atmosphere, from burning of fossil fuels Increased amounts of greenhouse gases like methane.
The Effects of Climate ChangePolar ice caps will melt causing massive flooding
The Effects of Climate ChangeMore severe weather systems or storms
The Effects of Climate ChangeIncreased distribution of insects that carry deadly diseases - MALARIA
The Effects of Climate ChangeThe environmental change favors certain species like rodents, weeds, and insects
The Effects of Climate ChangeIncreased droughts
Solutions for Climate ChangeCreate laws that limit carbon dioxide emissions – The Kyoto Treaty Use hybrid/electric cars Limit your energy consumption Educate people about the issues
Solutions for Climate ChangeUse of alternative energies Wind farms Solar farms Geothermal energy Nuclear energy
Pros and Cons of Nuclear EnergyLittle greenhouse gas emissions Readily available technology Huge amount of energy is generated from one single plant
Pros and Cons of Nuclear EnergyRisk of radioactive disaster Radioactive waste Heats up surrounding water often harming the ecosystem
Ozone Depletion Ozone layer protects the earth from harmful UV rays
Cause of Ozone DepletionEmission of Chlorofluorocarbons (CFC’s) into the atmosphere
Effect of Ozone DepletionIncrease UV rays increases the skin cancer rates
Effect of Ozone DepletionOther species of plants and animals may also be affected by UV radiation. The species’ genes will mutate sometimes causing cancer, death, or infertility.
Solution to Ozone DepletionThe use of CFC’s was banned by international law – Montreal Protocol of 1989

THE HUMAN IMPACT ON ECOSYSTEMS Pollution and Overpopulation can seriously damage the health of an ecosystem (the living and non-living factors in an area).
Earth Science 4.3 Water, Air, Land Resources
Human Impact on Ecosystems
Greenhouse gases in the atmosphere absorb and retain the energy radiated from land and ocean surfaces, thereby regulating Earth’s average surface temperature.
The Greenhouse Effect Presenters: Jaime Pinto & Nathalie Mokuba
Overpopulation ~7 billion people Many natural resources are nonrenewable More people means: –1) More forests removed –2) More resources consumed –3)

Ozone & Greenhouse Effect. What is Ozone? Ozone is a molecule that occurs in the Stratosphere Ozone absorbs harmful UV rays from the sun O 3 + uv O 2.
Greenhouse Effect - Natural Heating of Earth’s surface by certain atmospheric gases.
Pollution. Smog smog – mixture of chemicals that forms a haze in the air (Nitrogen Oxides etc) smoke from cars and factories release the chemicals.
What is Human Impact?. Ecology is the study of the interactions of organisms with its environment. Biodiversity is the variety of life in an area; # of.
The environment is all of our surroundings. This includes the atmosphere, oceans, soil and all living things.
