ENVIRONMENT PROBLEMS
Nowadays, environmental problems are getting worse and worse, it is an international problem. There are many different environment problems, for example: deforestation, bowel movements increases acid, increase in carbon dioxide emissions, destruction of the ozone layer, abuse of pesticides comings and other substances-toxic, destruction of tropical forests and Virgin Lands, drinking water shortage, nuclear waste...
Deforestation
Deforestation
Deforestation is the process of disappearance
of the forests, primarily caused by human activity. It is directly
caused by the action of man over nature, mainly due to logging carried out by
the timber industry, as well as to obtain land for agricultural crops.
Deforestation in the best of cases is a set of
trees placed according to a separation set artificially, among which there is a
herbaceous or shrubby vegetation that does not usually occur in the forest. In
the worst cases, non-indigenous trees that sometimes damage the substrate, as
in many plantations of pine, spruce or eucalyptus are planted.
And the worst of all is much worse than those
things and both may occur, but worst of all is that the improvement of this
forestation is in our hands,so we have to do something in order
to improve things.
Bowel movements increases acid
Acid precipitation, also associated with the
use of fossil fuels, has its cause in the emission of sulphur dioxide and
oxides of nitrogen for thermal power stations and motor vehicles exhausts.
These products interact with the light of the Sun and the humidity of the
atmosphere producing sulphuric and nitric, acids that are transported by
atmospheric circulation and fall to Earth, dragged by rain and snow in the
so-called acid rain, which has become a major global problem. The acidity of
some rainfall in Northern Europe and United States is equivalent to the
vinegar. Acid rain corrodes metals, wears the buildings and monuments of stone,
harms and kills the vegetation and lakes, streams and soils and both things
acidifies more…
So, instead of using so many toxic materials
to the environment, we could use another type of material or use this but with less frequent use and with more awareness
Bestruction of the ozone layer
On the other hand, we have the problem of the
ozone layer: the ozone layer is a region of the atmosphere that protects the
planet from harmful ultraviolet (UV) rays at high altitudes. If there were no
such gaseous layer, which lies about 40 km of altitude above the sea level, life
would be impossible on our planet. In the decades of 1970s and 1980s was found that
human activity was having a negative impact on the thickness of the layer. The
existence of a large hole centred over Antarctica was discovered in 1985. The
studies showed that the layer was being affected by the increasing use of
chlorofluorocarbons
I believe that this is the biggest problem of
all the problems of the environment, because as I mentioned before, if ozone was
destroyed, life would be impossible and would be the end of existence human and
vegetarian existent, for these reasons is very important to care for the environment,
because the future depends on us, and no more.
