Landfill
A landfill is a local for the disposal of waste materials by burial and is the oldest form of waste treatment. Landfills have been the most common methods of organized waste disposal and remain so in many places around the world.
There is alternatives to landfills are waste reduction and recycling strategies, like anaerobic digestion, composting, mechanical biological treatment, pyrolysis and plasma arc gasification, etc.

Ozone layer
The ozone layer has changed over the past 25 years, as the reduction of its thickness in Antarctica and, more recently, also in the North Pole. This is called the ozone hole.
The main responsability goes to the CFC's and HCFC's, although these are less common.

Imogen Heap - Hide and Seek
"Where are we? What the hell is going on?
The dust has only just began to fall
Crop circles in the carpet, sinking, feeling
Spin me around again and rub my eyes
This can't be happening
When busy streets a mess with people would stop to hold their heads heavy
Hide and seek
Trains and sewing machines?
All those years they were here first
Oily marks appear on walls
Where pleasue moments hung before
The takeover, the sweeping insensitivity of this
Still alive
Hide and seek
Trains and sewing machines?
Oh, you won't catch me around here
Blood and tears they were here first
Mm, what you say?
Oh that you only meant well, well of course you did
Mm, what you say?
Mm, that it's all for the best
Of course it isMm, what you say?
That it's just what we need
You decided this
Mm, what you say?
Mm, What did she say?
Ransom notes keep falling at your mouth
Mid-sweet talk, newspaper word cut outs
Speak no feeling no i don't believe you
You don't care a bit you don't care a bit
You don't care a bit
You don't care a bit
You don't care a bit
You don't care a bit
You don't care a bit."

Air pollution
Air pollution is the emission of polluting gases into the atmosphere. This can cause a degradation of ecosystems due to the launch of numerous substances into the air. This type of pollution can lead to the greenhouse effect, to climate change, to decline in air quality, to health problems in living beings and various respiratory diseases, various types of cancers, among others. One of the measures we can take to stop this serious problem is, for example, the use of public transport.

Soil pollution
The soil pollution affects particularly the top layer of the earth's crust, causing direct or indirect harm to human life, the nature and the environment in general. Is the undue presence in the soil of foreign elements, such as garbage that man produces, which adversely affects the life forms and regulate its development. The pollution of soil can be of two categories: urban and agricultural. One way of dealing with municipal waste is the allocation of places of deposit for them, known as landfills. In these places all the urban waste is deposited, without any form of treatment or recycling. The incineration of garbage is done in special furnaces. The process of incineration, however, involves the use of filters and reducing emission of toxic gases, including carbon monoxide, carbon dioxide and sulfur dioxide.

Noise pollution
Noise pollution differs significantly from other types of pollution in that, the noise is produced everywhere, therefore, it's not easy to control it; differentiates itself by not leave waste on the environment; is only noticed in the proximities of the source; there is more demand for political action on other types of pollution than on noise pollution, and noise, despite not having effects generic cause inconvenience, frustration, is aggressive to the ear and cause nervousness. However, it's a way to combat pollution that is needed.

Deforestation
Deforestation is a common problem in our daily lives that causes many environmental impacts such as the emission of greenhouse gases or the loss of biodiversity on the planet, resulting in a mass extinction of various types of species. One of the solutions is reforestation.

Renewable energy
Renewable energy is a form of energy capable of regenerating. it is an inexhaustible source.. the types of renewable energy are: solar eergy; wind energy; hydropower energy; tidal energy; the wave energy; biomass ans geothermal energy. The advantage of using renewable energy resources that these produce no emissions of nocive and pollutant gases, contrary to what happens with non-renewable energy.

Florestal fires
The causes of florestal fires have, in it's majority, an human origin, either by accident or intentionally. The fires from natural causes account for a small percentage of the total number of fires. The fire causes other major problems, such as global warming. It is for these reasons that we have to take action against the problems. We should not make fires on land located within the woods and do not launch rockets or fireworks, near forests.

Acid rain
Acid rain is a form of precipitation that is, unusually, acidic. the main cause is the presence of sulfur and nitrogen in the atmosphere. to stop this problem, many factories use a filter to prevent the exit of this acids. we can do many things to stop this problem: for example, we can travel by bus or use an energy source less pollutant.
