The document discusses several key environmental issues including climate change, acid rain, the hole in the ozone layer, endangered species, and deforestation. It notes that climate change is being caused by human activities like industry and transportation which are warming the planet and raising CO2 and temperature levels. Acid rain occurs when nitric and sulfuric oxides mix with water, damaging vegetation. The hole in the ozone layer was caused by CFCs from sprays destroying ozone particles and allowing harmful UV rays through. Endangered species are at risk due to human destruction of natural habitats and overexploitation of resources. The document encourages more sustainable lifestyles to help address these issues.

1. ENVIRONMENT

2. Environment: set of natural, Cultural and social values. Made up: biocenosis (flora + fauna), Biotope (air, water, soil) and human being. The relationship between them can cause environmental impacts. Environmental impacts: Climate change Acid rain Hole in the ozone layer Endangered species Deforestation Etc.

3. Climate change Natural + anthropic Human activities are warming up the planet (Industry,transport) Consequences: CO2 in atmosphere ( Greenhouse effect ) Temperature increasing ( Global warming ) Ice cap melting Sea level raising

4. Acid rain Nitric and Sulphuric oxides in the air mix with atmospheric water destroying vegetation when it rains.

5. Hole in the ozone layer CFC ( Chlorofluorocarbon )from the sprays destroys the ozone particles in the atmosphere. The hole in the ozone allows the ultraviolet and other harmful rays go through. Consequences : Health problems like skin cancer. Altough CFC was forbbiden it persists for decades.

6. Endangered species Human beings destroy the natural habitat of animals and vegetation, also the natural resources exploitation cause a high risk situation with biodiversity extinction. Deforestation, urbanization of natural ecosystems, non native species, lakes and rivers pollution, are the main responsibles.

7. WHAT CAN WE DO? Be sustentainable in your lifestyle. Think green daily, even at work. Save resources. Reduce, reuse, recycle Don’t waste energy
