How we do change the world…
We live in a community that has many problems. One of
these problems are the trash on the streets. Currently you cannot walk in the
streets without you may encounter with a
large quantity of waste, due to the lack of concern and awareness of
society on the subject.
Plastic bags, papers, bottles and many other discards
are commonly found on the public streets, roads and vacant lots. This practice
performed by a great number of people, implies very bad consequences to the
environment and cities. For example, the constant floods occurred in large
cities due to the large volume of trash found in culverts. Another problem also
encountered in our daily life is the dumps: large deposits of garbage to open
sky which, despite being more "economic”, aggravate the pollution of the
soil.
For the reduction of this problem, people needs to have more awareness about the subject, may
be diffused through awareness campaigns, is by means of advertisements in
various media, telecommunication (TV, radio and the internet, mainly by social
networks) or by an increase in the investment of funds to the cities. Among the
possible solutions, one of the most widespread nowadays it would be the
recycling that would help with the reduction in extraction of raw material for
natural materials already recycled avoiding the great devastation of the
environment.

CO2 Emissions
The idea that CO2 is the responsible,
or the main, for global warming is easily accepted by most today. But there
isn't evidence shows that CO2 control the Earth's climate, and case control,
the human interference is insignificant in this respect.
This story of global warming, has been present in the past, where global temperatures were higher than today's. Over time there was also a drop in temperature, and this variation is constant in the history of the earth. We note that independent of men, changes in global temperature are inevitable.
Even so, we are often influenced to mobilize to reduce our CO2 emissions, with drastically interfere in our day to day, until well buy expensive products called "green products". But research shows that relative the emitters of CO2 in the atmosphere terrestrial, the human action has an insignificant portion, which makes all this mobilization useless.
So, the CO2 emitted by human activity doesn't interfere significantly in the global climate, but that doesn't mean we can pollute and do whatever they want in relation to the environment. We have that be aware of environment and act politely, to do our role in a healthy lifestyle and a good local climate of urban cities.
Those many errors in this idea of CO2 and human action in the supposed global warming aren't showed, due to the interests of other, more powerful economically. For better explain on the matter, i advise to attend a lecture by Professor da USP Ricardo Augusto Felício, available on Youtube.

The Amazon Deforestation
In recent years the Amazon forest,
located in the northern region of South America, is being severely damaged.
Many loggers are in search of raw material for making furniture, paper and
charcoal. There are also many farmers who are in search of new areas for
breeding and planting. Currently, there is serious concern about the situation
of the forest: the reduction of the forest area and the loss of oxygen
influence on the local climate, affecting the water cycle, without forgetting
the issuance of oxygen will decrease.
Between 1991 and 2011 the area has
greatly increased deforestation and now has about 800,000 km ². Since 2004, the
pace has been decreasing, reaching a record high of minimal. The deliberate
fires are the main causes of deforestation, but the cut is also present.
The deforestation affects local
biodiversity. The animals are left without their habitat. Many species are
becoming extinct every year, animals and plants. Do not forget that most of the
planet's fresh water is there. With fewer trees, water cycle is affected,
thereby decreasing the amount of water present. The Amazon is one of the largest
oxygen responsible for control of the planet. Less trees, less air.
Currently the government has serious
oversight, but there's still plenty to do. Gradually, deforestation is reduced,
and people will be more aware about their own life.
