World Environment Day | Giornata mondiale dell’ambiente

The World Environment Day è la giornata mondiale che United Nations ha creato per incoraggiare tutti ad essere più protettivi dell’ambiente. Questo è il messaggio offerto dalle Nazioni Unite:


“This is our moment. We cannot turn back time. But we can grow trees, green our cities, rewild our gardens, change our diets and clean up rivers and coasts. We are the generation that can make peace with nature. Let’s get active, not anxious. Let’s be bold, not timid.”


Ecco alcuni dei problemi:

Climate change

Climate change, also called global warming, refers to the changes in the climate and a rise (un aumento) in the average (media) temperatures on Earth.

Deforestation

Rainforests help to control global warming because they absorb carbon dioxide. In recent years, larges areas have been destroyed, as trees are cut down for wood or burned to clear the land for farming (agricoltura). The burning (la combustione) releases (rilascia) large amounts of carbon dioxide into the atmosphere.

Pollution

Air pollution and climate change are closely linked. Often it is the same gases that create the poor air quality in cities which can cause serious health problems for people living in urban areas. Water pollution is a huge problem and unclean water is a major threat (minaccia) to human health. Soil (terreno) pollution is also a big problem. The use of fertilizer and pesticides can contaminate land and threaten (minacciare) food security.

Recycling

Recycling is the processing of used objects and materials so that they can be used again. About 60% of rubbish from homes and factories contain materials that could be recycled. Recycling saves energy and also reduces damage to the countryside.

Renewable energy

Up until now, most of the energy we used came from coal (carbone), oil and gas. But these will not last forever and burning them is a major cause of climate change. Many countries are now choosing to use renewable sources for their energy needs. Solar energy from the sun, wind power from turbines, hydroelectric energy from rivers and sea water are the main sources of renewable energy.

Public transport

Transport has a large environmental impact. People use cars more, especially in urban areas and this is one of the largest growing (crescente) sources of carbon dioxide in the world. By using public transport (buses, trains, metros) or cycling in cities emissions from urban transport could be cut (ridotta) by more than (più di)  50%.
