ENVIRONMENTAL SUSTAINABILITY
Meaning
Meeting the needs of the present without compromising the ability of future generations to meet their own needs
Importance
To preserve resources for future generations
Clean air
Clean water
Wildlife
Ensuring that human society operates with ecological borders
Planetary boundary (PB) concept
Our Role
Large system to change
SNHU
President, university's Board of Trustees and senior leadership understand that it is the right thing to do
The staff, faculty & students expressed interest in university-wide commitment
92% of college students agreed - Institutions incorporate & promote sustainable development
Ways To Achieve Environmental Sustainable
Clean water and sanitation
●Learn to avoid wasting water
Climate action
●Acting now to stop global warming
Life below water
●Avoide the use of plastic bags to keep ocean
clean
Life on land
●Planting trees
Responsible consumption and production
● Recycling items
Sustainable cities and communities
●Biking, walking or using public transportation
What Can I Do With Environmental Science Degree?
Environmental scientist

Engineer
HUMAN ACTIVITES THAT AFFECT AN ECOSYSTEM
All living things and non-living things
Human actions that affect ecosystem balance
Agriculture
Destruction of wildlife
●Population growth-i fluenced deforestation
Global warming & climate change
Aquatic resources degradation
● Vast amount of phosphorus & nitrogen nutrients i to natural soils, land & water
Deforestation
Forest or stand of trees is removed.
Results in a loss of biodiversity
Increases greenhouse gases within the atmosphere
Overpopulation & overconsumption
Require lots of space
Ecosystem damage
Do not have enough trees ti filter the air, CO2 level increase
Consume large amounts of resources for our own needs
Plastic production
Floating around the world oceans
Emission of carbon dioxide and other greenhouse gases
Methane & hydrofluorocarbons (HFCs)
Global temperatures are on the rise contributing to sea-level rise amd exreme weather
Destruction of the reefs
Water pollution, climate change, overfishing and acidification of marine waters
Reefs provide shelter, productive ground
Production of black carbon
Produced from cooking with solid animal fuels, burning firewoods, diesel car exhausts, burning of trees
Creates heat-absorbing layer(increased global temperatures)
Draining streams / rivers and destruction of critical freshwater qauifer recharge areas
Large amounts of chemical fertilizers, herbicides & other agrochemicals
Increased salt concentration in lakes
Overhunting and overexploitation
Caused a reduction in the number of varied plant and animal species
Caused extinction, destroy natural reserves and breading areas
Genetic modification
Invasive species
Transporting species either intentionally or accidentally from other areas of the world
