Overexploitation
Habitat Loss
Air pollution causes rain to become acidic below pH of 7
The fertilizers can cause algal blooms
Air pollution causes rain to become acidic (below pH of 7)
Damages the soil
It kills trees and destroys leaves
Lowers pH of lakes, oceans, and killing the organisms
The Wetlands are the natural filter

When humans use natural resources over population and pollution starts to happen.
It usually causes a disruption in the ecosystem.
When humans care about money animal conservation and natural resources happens.
We destroy relationships with other animals for money.

People destroy habitats everywhere some things they destroy habitats is natural resources, places to grow food, and room for infrastructure.
The rabbit populations eat themselves into starvation.
Organisms aren't harmful because of what they are it's because they're happen to be.
The vines grew uncontrollably until it became known as the plant that ate the south .
In Australia, the European rabbits eat many plants that they wipe out the food supply for themselves and other herbivores .
The amount of edible plants effects the population of herbivores.
And the healthy predator population keeps the herbivores from becoming to numerous .
It protects & converses the biodiversity.
Its the use of natural resources in a way that meets the needs of a present
The Umbrella species is a species that if it's protected it also provides protection to other organisms by default.

In the cold adapted species . Ex: Polar bears
Shoreline Erosion
97% of the climate scientists agree that this new tendesty is not caused by the variation of the earths orbit .
It causes very dangerous storms
Human health problems
Crop losses
It causes to have droughts and water shortages
It changes the pattern of the precipitation
Human population is rising fast and there taking up the animals habitats.
If we keep taking up the animals habitats for new homes animals are going to start going extinct.
10 out of the last 13 years were the warmest in record
The people cut the fins off of sharks and release them to a slow and very unpleasant death.
One of the major things in extinction is we hunt some species to oblivion.
We do not know how many sharks are in the ocean but we know that the apex shark have been declined between ninety and ninety nine percent.
Sharks have been targeted by pleats around the world.
Sharks have survived for massive extinction events.
Sharks have been here before dinosaurs.
The air pollution affects the pollution .
It increases in concentration of a substance as it moves up in the food chain .
The DDT is a chemical pesticide .
DDT was very popular but soon it became under scrutiny. It became that this pesticide was having some negative environmental effects .
But the DDT is far more regulated and controlled in its use today .
Biomagnification describes what happens when toxins become more concentrated in the living tissues that go up in the food chain .
A little over 200 years ago the human population was 1/7 of what it is today .
At the moment, it has been estimated that there is possibly 7 billion humans on this earth .
That population can be about 11 billion humans in 2050 .
Today there are 5.3 billion people living in developing nations .
