Describe some climatic changes in the world. What may these changes lead to in the future?
One of the most important climatic changes in the world is the global warming,which refers to an unequivocal and continuing rise in the average temperature of Earth's climate system. This phenomenon is cause by the pollution, mainly caused by the people. The increasing temperature of The Earth can lead to several problems, such as a rise in sea levels and a change in the amount and pattern of precipitation, the expansion of subtropical deserts; more frequent extreme weather events including heat waves, droughts and heavy rainfall; ocean acidification; species extinctions due to shifting temperature regimes; and significant effects to humans including the threat to food security from decreasing crop yields and the loss of habitat from inundation.
Other important climatic change in the world is the Climate change, which is a change in the normal climatic conditions of the Earth over periods ranging from decades to millions of years. It is sometimes caused by global warming. It can be caused too by factors such as biotic processes, variations in solar radiation received by Earth, tectonics plate, and volcanic eruptions. If this phenomenon continues taking place, the planet will suffer a lot of changes in the future, such as an increase in global temperature; an increase in the sea level; endangered in a lot of vegetal and animal species; and impacts on human health.
If we continue polluting, these problems will get bigger and we will destroy the only planet we have to live. The most worrisome is that it seems that people don’t get worried about this. We continue polluting, using the car when it isn’t necessary; building factories that loose a lot of CO2 and other gases, that are harmful for the planet; and destroying forest, that are the principal source of oxygen. I think that all this is because we think that we are the owners of the planet for supposedly being the most intelligent species. But I don’t find nothing sillier than damaging gently the only place we have to live needlessly. Because, for me isn’t necessary to build more houses, towns, factories, shopping centres, etc. And, in my opinion, if people put more effort planting trees than polluting the planet, the Earth would be a better place to live.
However, we have to think too that a lot of remedies exist to end with these climatic problems. Some of these remedies are saving energy, switching off the lights or turning off the faucet when we don’t need it, and having a shower instead of taking a bath; use the car only when it’s absolutely necessary and try to take public transport, or go walking if we can. Moreover all us should recycle our reusable waste and trash.
Maybe all these things take an effort to us. But if we start doing these everyday we will realise that this is something so easy and that is worth. And it will help too to fell better with ourselves.
