  1. How Humans Impact the Environment and What We Can Do to Help Reduce Our Impact By: 4th Block Honors Biology

  2. Acid Rain Chris, Lewis, Faith 2/19/13 Block 4

  3. Acid rain • Acid rain can wear away metals and stone • It is a weak acid • It contains low ph to 4-6 • It damages buildings, and kills plants • The gases from burning fuels mix with the rain • Acid rain has been around for 200 years

  4. Causes and Effects of Acid Rain • is caused by emissions of sulfur dioxide and nitrogen oxide which react with the water molecules in the atmosphere to produce acids • Human burning fossil fuels • It decays building, statues, and sculptures • Acid rain can kills plants and trees

  5. Possible solutions or sustainable practices • Converse energy • Carpool, walk or bike instead of driving • Alternative energy resources • Clean up smokestacks and exhaust pipes

  6. Habitat Destruction By: Mary Kathryn High, Nick Ellis, Josh Whitley

  7. What is habitat destruction? • Habitat Destruction is when humans or other species take over or destroy the home of another. • It is mainly caused by human activity due to harvesting, natural resources for industry production and urbanization. • Habitat Destruction is one of the main threats to biodiversity.

  8. Causes of Habitat Destruction • Logging • Agriculture • Building Road and Cities • Forest Fires • Dams • Mining • Alien Invasions • Natural Environment Changes

  9. Solutions • Make T-shirts made of hemp • Wear synthetic fabrics • Recycle water bottles to make clothes • Use jeans as house insulation • Use vinyl billboards to make purses • Use pig urine to make plastic plates

  10. Introducing InvasiveSpecies Eynde Frazier, Adan Ruiz, & Courtney Sholar 2/15/2013 Period 4

  11. The Environmental Problem • An invasive species is a non-native species whose introduction does (or is likely to) cause economic or environmental harm or harm to human health • They are harmless plants and/or animals that humans transport around the world either accidently or intentionally; introduced into new habitats, these organisms reproduce rapidly, they increase their populations because their new habitat lacks the parasites and predators that control their population “back home” • because of their lack of a death rate, the domination of their species can potentially damage nature Courtney Sholar

  12. Human Causes • Verify that the plants you are buying for your yard or garden are not invasive • When boating, clean your boat thoroughly before transporting it to a different body of water • Clean your boots before you hike in a new area to get rid of hitchhiking weed seeds and pathogens. • Don't "pack a pest" when traveling. Fruits and vegetables, plants, insects and animals can carry pests or become invasive themselves • Don’t move firewood, clean your bags and boots after each hike, and throw out food before you travel from place to place • Don't release aquarium fish and plants, live bait or other exotic animals into the wild  • Volunteer at your local park, refuge or other wildlife area to help remove invasive species Eynde Frazier

  13. Human causes & Environmental effects • Because they bring them from around the world • Leafy spurge effects millions of grasslands in (Northern Great Plains) by infesting them. Adan Ruiz

  14. Global Warming By: Taylor Davis Juan Borja Joseph Barnes

  15. Information • Global warming is the process of greenhouse gases trapping heat from the sun. This trapped heat causes extreme climate changes. • Global warming first occurred in the 19th century as fossil fueled vehicles were created.

  16. Causes and Effects Cause • Emissions from fossil fuels • Greenhouse gasses trap heat • Deforestation Effects • Sea level rising • Ice caps are melting • Precipitation is increasing

  17. Sustainable Practices • Phasing out fossil fuel energy • Boosting energy efficiency • Managing forest and agriculture • Developing and deploying new low-carbon and zero-carbon technologies • Exploring nuclear energy

  18. Biodiversity loss Kiara Pitt, Brittany Bullock, and Teddy Blume February 19, 2013 Block: 4

  19. Kiara PittResources: www.goggle.com, and www.gloalissues.org • Biodiversity loss means the loss of biomass and biological diversity in an environment. • When biodiversity declines severely, we call the result desertification. • Ex. Fish stocks and dwindling, and forest loss.

  20. Causes and Effects Brittany BullockRainforestconservation.org

  21. SolutionsTeddy Blumewww.google.com and www.ecological-problems.blogspot.com • Stopping deforestation • Reduce environmental pollution • Protecting native species • Stop climate change from running out of control

  22. PESTICIDE OVERUSE! BY: RJ COSIMENO NICK TAYLOR LOGAN FRIESEN

  23. PESTICIDES! • PESTICIDES ARE A REPELLENT THAT KEEPS BUGS OFF OF PLANTS AND WHATEVER ELSE PEOPLE SPRAY IT ON. RJ • DDT IS A PESTICIDE THEY USED THEN HAD TO BAN DUE TO ENDANGERMENT

  24. CAUSES & EFFECTS ON ENVIRONMENT • CAUSES : FARMERS PUT PESTICIDES ON PLANTS TO STOP INSECTS FROM DAMAGING OR DESTROYING CROPS! • USE PESTICIDES ON LARGE FARMS! • EFFECTS : THEY HARM USEFUL INSECTS LIKE BEES! • KILLS WEED AND FUNGI WHILE THEY’RE DOING IMPORTNANT JOBS! • PESTICIDES CAN SPREAD TO OTHER AREAS! • CAN CAUSE PROBLEMS ON ORGANIC FARMS! LOGAN

  25. SOLUTIONS • STOP USING SUCH HARMFUL PESTICIDESPESTICIDES FROM GETTING INTO WATER STREAMS! • HAVE SMALLER BOUNDARIES TO PUT THEM ON! • ! • USE LESS PESTICIDES! • GROW VEGETATION TO STOP NICK

  26. Land Pollution By Chris Tinder, Taylor Battle, Cheyenne Carico

  27. General Research • Land pollution is the deposition of solid or liquid waste materials on land or underground in a manner that can contaminate the soil and groundwater, threaten public health, and cause unsightly conditions and nuisances. Taylor Battle Research: www.britannica.com

  28. Causes and Effects • Land pollution is caused by toxic chemicals, human waste and pest control substances. • This leads to plants dying, soil loses vital nutrient for plant growth, and can kill vital animals and plant species if it gets into water sources. Chris Tinder Resource: www.ehow.com

  29. Possible Solutions • 3 R’s Reduce, Reuse, Recycle. • Reduce the amount of toxic waste that is released into the environment • Find safer pest control substances for the environment. Cheyenne Carico Resource: Library Books

  30. Air Pollution By: Justin Coley, Shy Barnes, KaileyAycock

  31. Why it’s an issue… • Air pollutants- are dangerous things that make the air unclean and come in the form of gases and particles. • Air pollutants are outdoors and in indoors. • In 1952, London England experienced the “Smog Disaster” killing four thousand people in effect of the high concentrations of pollutions.

  32. Causes of air pollution • Burning fossil fuels, coals that release nitrogen and sulfur compounds into the atmosphere create Air pollution. • Another example of a cause of air pollution is house hold cleaning products ore painting supplies people use everyday. • The environmental effects are chemical reaction involving air pollutant can create acidic compounds which can cause harm to vegetation and buildings.

  33. Possible Solutions & Sustainable Practices • Solutions: Stop littering, don’t burn your trash, tires, leaves ect. • Practices: Eat more natural foods, instead of packaged, processed foods. • Carpooling, to burn less gas. • Use recyclable items and eco-friendly light bulbs
