GMF (Geneticaly Modified Food)
The Geneticaly Modified Food (GMF)are organisms manipulated geneticaly with the objective to improve their caracteristics.
This process had vantages and disavantages.
Some vantages are the big raise of production, incriase the plant resistence, the aliment can be enriched with essential nutrients, production of species with new caracteristics and no implicite spens a lot of money.
Some disadvantages are the inpoverisment of biodiversity, production of new's virus in Nature, geneticaly polution and may be afects the Human Healty.
the scientistss don´t have sure about the dangerous of the GMF, because this kind of studyies can last centuries.
Tourism and Eco-tourism
The impact of tourism reflected in:
-Pollution of the air because of the higher energy consumption and the increase of traffic car
-The increase of pollution of water
-Destruction of Natural Landscape, the Fauna and Flora
-In the degradation of the landscape of historic sites, monuments and areas of scientific value
Ecotourism is a variant of tourism that develops in virgin natural areas in order to admire, study, enjoy the trip, know the plants, seeing and hearing animals, the cultural marks of the past and present areas where it is practiced.
It is practiced in protected areas, so tourists have to meet rules to preserve ecosystems in their natural state and its wildlife.
From the moment the human being intervenes in the natural habitat that affect it.
The preocupation is preserve habitats and develop the local economy at the same time.
Renewable and Non Renewable Energies
The Renewable energies came from natural resorces like sun, water, wind, heat, among others... All of them have two things in commun, they are inexhaustible and clean.
-Solar energy provided from sun, and can be used to produce electrical energy or can be used to warm water.
-Wind energy provide from wind and it´s used to produce electrical energy.
-Energy hydraulic provided from the water pressure and it´s used to produce electrical energy.
-Geothermal energy provided from Earth heat, it´s used to produce electrical energy and heat water.
Nowadays the most of electrical energy is produced by burning fossil fuels, like petroleum or coal, but these methods are polluting.

The Animal Testing
For us, these tests in animals are a crime and should end, because these tests can bring a lot of injuries for the animals and in some cases they can die.
In some cases, these tests are solutions for the developmet of various treatments and will be used by Humans.
The products used in the future like drugs, vaccines and new treatments.
