Environmental Science
INTRODUCTION
Environmental Science is the systematic study of our environment and our proper place in it.
INTERDISCIPLINES OF ENVIRONMENTAL SCIENCE
PROBLEMS ENCOUNTERED
POLLUTION
It is the introduction of harmful materials in the environment
LOST BIODIVERSITY
It is the extinction of species worldwide and the local reduction of species in certain habitat.
CAUSES OF POLLUTION
Burning of Fossil Fuels
-
Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles
-
Carbon monoxide and nitrogen oxides emission from vehicles
Agricultural Activities
-
Ammonia is a very common by-product from agriculture related activities and is one of the most hazardous gases in the atmosphere
-
Use of pesticides, insecticides and fertilizers n agricultural activities
Exhaust from factories and Industries
-
Manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds and chemicals into the air thereby depleting the air quality
Mining Operations
-
Wherein minerals below the Earth are extracted using large equipments
-
During the process of mining, dust and chemicals are released in the are causing massive air pollution
Indoor Air Pollution
-
Household cleaning agent or products, painting supplies emit toxic chemicals in the air and cause air pollution
-
Suspended Particulate Matter (SPM), refers to the particles afloat in the air and is usually caused by dust, combustion, etc.
EFFECTS OF AIR POLLUTION
Respiratory Problems
Heart Problems
Global Warming
Acid Rain
Eutrophication
A condition in where a high amount of nitrogen present in some pollutants gets developed on sea's surface and turns itself into algae and adversely affect fish, plants and animal species.
Depletion of ozone layer
SOLUTIONS FOR AIR POLLUTION
Use public transportation
Conserve Energy
Understand the concept of Reduce, Reuse, & Recycle
Emphasis on Clean Energy Resources
LOSS OF BIODIVERSITY
Habitat Loss
It is the thinning, fragmenting, or outright destruction of ecosystem's plant, soil, hydrologic and nutrient resources
Overexploitation
The process of harvesting too many aquatic or terrestrial animals or plants, which depletes the stock of some species while driving others to extinction
Invasive Species
It is any nonnative species that significantly modifies or disrupts the ecosystem it colonizes
Pollution
The addition of any substance or any form of energy to environment at a rate faster than it can be rendered harmless
Climate Change Associated with Global Warming
The modification of Earth's climate associated with rising levels of greenhouse gases in the atmosphere over the past one to two centuries
INFLUENCERS
Human Population Growth
Increasing Consumption
Reduced Resource Efficiency
WASTE MANAGEMENT
The process of treating solid wastes and offers variety of solutions for recycling items that don't belong to trash
Landfills
The most popular method of waste disposal. It is the method of burying the waste in the land.
Incineration/ Combustion
The burning of wastes or applying thermal treatment wherein solid waste material are converted into heat, gas, stream and ash.
Recovery and Recycling
The 3R's: Reduce. reuse and recycle.
Composting
The natural bio-degradation process that takes organic wastes
Waste Minimization
