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.

Greenhouse Effect and Consequences

It is a process that happens when a part of solar radiation reflected by the Earth's surface is absorbed by gases in the atmosphere. So the heat is retained and as consequence the global temperature will increase. The most dangerous are CFC's.


Climate changes refer to changes in global climate. These variations are relate to changes in temperature, precipitation and others. Such variations can change the weather characteristics according to rating didactic.
So we understand that climate change may be an effect of natural processes or due to human action.
