Preventing Biodiversity Loss

Most of habitat loss is because of mankind's decisions and some of the affects this had was....

Bio fragmentation

the division of a large habitat area into smaller areas. Affects the amount and type of species that live in the smaller areas.

Deforestation

the action of clearing a wide area of trees.

Overpopulation

The reasons were Natural Resources,Room for food, Room for Infrastructure

Pollution

the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects.

the condition of being populated with excessively large numbers.

What is an "Alien Species" ?

The introduction of species into a habitat that wasn’t originally found in that area.

How is it Harmful?

When a species is brought over from a different habitat, there is a chance that the species will overpopulate and will "take out" the other remaining organisms

What are some examples?

Asian beetles, zebra mussels, water milfoil, buckthorn, carp, domestic cats

What is Air Pollution?

Consists of chemical substances and particles released into the atmosphere, mainly by human activities

What are the causes of Air Pollution?

The major cause of it is the burning of fossil fuels in factory

what is Water Pollution?

the contamination of water bodies

What are the causes of Water Pollution

The most constant cause of water water pollution is Fertilizer that causes Algea blooms

What is Acid Rain?

When pollution hits the air, the rain becomes acidic

How does Acid Rain form?

The pollution of air causes the the rain to have a ph of under 7 that causes it to become acidic

What is Overpopulation?

the condition of being populated with excessively large numbers.

Problems with human overpopulation

habitt loss due to human expansion for buildings,fishing, agricultural use

what is overexploitation?

the basic overuse of animals and land that leads to a decrease in populations.

Problems with overexploitation

Since we hunt animals, we tend to get a head of ourselves and in return, this will cause the species to become extinct

What is Biomagnification?

What is Pollution?

Increase in concentration of a substance as it moves up the food chain

Addition of chemicals, noise, heat, or even light beyond the capacity of the environment

what does biomagnification do?

On a food chain, the last organism has a higher concentration of the toxin

What is Climate Change?

CO2 from burning fossil fuels increases the greenhouse effect

Effects of Climate Change

Decline in cold-adapted species

Melting of glaciers and rising sea levels

Coastal flooding and shoreline erosion

Major crop losses

Changing patterns of precipitation

What is sustainable use?

the use of natural resources in a way that meets the needs of the present and preserves the resources for the future ?

What are Umbrella Species?

A species that, if protected, also provides protection to other organisms by default.

why are Umbrella Spceies important?

The can save more organisms
