*Loss of biodiversity - Means that species are going extinct.
Extinction rate - 50 species per day - Going into our 6th major extinction period.
Domino effect - The loss of 1 species results in the losses of others that depend on that species.
Habitat Loss - Humans developing native vegetation - Most native prairies are gone.
Overexploitation - Poaching especially endangered species for horns, tusks, bones, gall bladder - Overfishing
Introduced Species - Species that are not native to an area.
*Deforestation - where the tree cover is removed or destroyed. - 3,000 acres/hr of tropical rain forest.
Soil erosion - Topsoil washing into streams and rivers.
*Hazardous waste disposal - We generate a lot of waste with nowhere to put it.
*Environmental Estrogens - BPA - Any chemical that breaks down into "Estrogen like" compounds.
*Water pollution - Dumping our wastes into streams and rivers.
Biological magnification - "Fat soluble" poisons in the environment will increase in concentrations as they move up the Trophic Levels (a food web).
*Acid rain - Precipitation (rain) that contains dangerously high levels of sulfuric acid and nitric acid.
Sulfur dioxide -> turns into Sulfuric Acid in the clouds.
Nitric oxides -> turns into Nitric Acid in the clouds.
Cuticle - The waxy coating on leaves. Gets dissolved.
*Climate Change - An increase in global temperatures (global warming). Decrease humidity, decrease biodiversity, increase drought, milder winters.
Greenhouse gases - Come from burning fossil fuels, from coolants (freon gas), and from industrial by-products.
CO2, methane, nitrous oxides, CFC's - We release 25 billion tons of CO2/year into the atmosphere.
Greenhouse effect - greenhouse gasses acts as a shield/barrier to trap excess heat in the atmosphere.
Drought - It is a lack of rain - we are running out of drinking water and water to use in our households.
