Ecology Challenges & Environmental Issues
Ecology |
study of how living things interact with one another in the Earth’s ecosystem (air, water, land)
|
Ecosystem Threats
Renewable vs Nonrenewable |
Water renewable right now, but not fresh/drinkable
Air renewable right now, but fresh/breathable is not Land is renewable b/c you can make more and if you let it regenerate, but not if we overuse good land |
Ecosystem Threats
Current & Future Pressures |
Exponential growth: of the world's population [certain areas at certain times]
Income Inequality: poor individuals are unable to make resources renewable so they use more than they should and rich people use more than they need |
Global Commons
Tragedy of the Commons |
Shared resources that a group uses collectively
If all individuals attempt to maximize their own private advantage in the short term, the commons may be destroyed and all users lose [individual freedom vs freedom of others to use the resource] Tragedy of the Commons: Freedom in a common brings ruin to all |
Sustainable Development
|
Meets the needs of the present without compromising the ability of future generations to meet their own needs
Eradicate poverty and develop the world economy in a way that doesn't degrade the environment |
Earth's Carrying Capacity
|
world’s resource base is essentially finite and bounded
Ecological footprint: what you need to consume in resources (land/water/food) in order to live
|
Global Environmental Issues
Ozone Depletion |
Protects earth from UV rays - it is being depleted, causes ice caps to melt and messes up the weather because the earth warms
|
Global Environmental Issues
Global Warming/Climate Change |
Increase in green house gases keeps the UV rays in which also warms the Earth
Caused by burning fossil fuels, black carbon, deforestation and beef production. Causes erratic weather, tidal changes and desertification |
Global Environmental Issues
1. Decline of Biodiversity 2. Threats to Marine Ecosystem |
1. Certain species are becoming extinct because mankind is killing them, humans tampering with the food cycle and environment destroying habits.
2. Overfishing, contaminating the water, destroying coral reefs, water temp |
