THE

ENVIRONMENT

Introduction.

Environmental problems:

Acid rain

Hole in the ozone layer

Greenhouse effect and global warming

Conclusion.

ACID RAIN

Acid rain is caused by nitrogen oxids and sulfur dioxide.

Destruction of natural

habitats.

CONSEQUENCES OF ACID RAIN:

Deterioration of

monuments.

HOLE IN THE OZONE LAYER:

It´s caused by chlorofluorocarbons gases (CFC).

CONSEQUENCES OF THE HOLE IN THE OZONE

LAYER:

Increase of skin cancer and ultraviolet

radiation-related diseases.

The evolution of the

hole in the ozone layer:

GREENHOUSE EFFECT AND GLOBAL WARMING:

It´s caused by carbon dioxide and other heat-

trapping gases.

This layer acts as a greenhouse and warms

the earth, causing global warming.

CONSEQUENCES OF GLOBAL WARMING: Decrease of snow cover and sea ice extension.

Rise in global average sea level.

Increase in the frequency of extreme precipitation events.

Increase in the average temperature.

ACTIONS:

Reduce emission of heat-trapping

gases, especially carbon dioxide.

Use energy-efficient appliances.

Use less electricity.

Recycling.

Use of renewable energy sources like wind

and solar.

CONCLUSION: Our stylelife is opposite to preserve the environment.

We buy a lot of things and them generate a lot of waste.

People know they can do but, it isn´t interesting.

Dump electronic
