Students express their opinion about climate change and look for their own solutions.

They think that irresponsible human activities, such as burning fossil fuels, cutting down forests and pollution, generate huge amounts of greenhouse gases, in addition to those already naturally present in the atmosphere, thus contributing to the greenhouse effect and global warming. 

Causes of increased emissions • Burning of coal, oil and natural gas • Cutting down trees (deforestation). Trees help regulate climatic conditions by absorbing CO2 from the atmosphere • Nitrogen-containing fertilizers and pollutes • Intensifying animal growth Cattle and sheep produce large amounts of methane during digestion.
