A healthy Biodiversity means a healthy enviroment

New medicines and cures for diseases can be made

Better resistance when faced with challenges like natural disasters

Water pollution

Water that is polluted by humans and animals. Things that pollute water.. such as ferterlizer

Aquifer

A large place where water is being purified

Desalination

The removal of salt (especially in salt water)

Water purification

Definition; Water purification is the process of removing undesirable chemicals, materials, and biological contaminants from raw water

Watershed

Definition; a ridge of land that separates two adjacent river systems

Impermeable

Surface that does not allow water to get into the ground. Therefore it runs off into storm drains

Erosion

the wearing away of the land surface by wind or water

Runoff

chemicals that go into storm drains and then sent to rivers and streams which then the rivers and streams become polluted.

Wetlands

wetlands are lands on which water covers the soil

Urbanization

Rapid and massive growth of cities

Sources

Non-point sources - sources that cannot be traced back to where they came from

Point source - sources that can be traced back to where the originally came from

Pollutants

Organic pollutants

Inorganic pollutants

Natural Resources

Non-renewable resource definition - Material or energy source that cannot be replaced within a human life span. ex/ minerals, metals

Renewable resource definition - Any material or energy source that cycles or can be replaced within a human life span. ex/ water, sunlight,

Definition; Resources that are produced by nature; found in earth. ex/ wind, steel, food, rocks
