In the last years, the people thought about ways to care environmental because the humans introduced external substances into the environment. If we can't be aware of this, there will be terrible consequences on people and the planet like destruction of the biodiversity, increased mortality of the humans and animal species, etc.
Some examples of contamination in our ecosystem are:
-The ozone layer is the second layer of the Earth’s atmosphere. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals. The ozone layer is getting thinner because the factorie's smoke, car's smoke and nuclear plants have damaged it . ''Ozone holes'' are popular names for areas of damage to the ozone layer but the scientists observed the first signs that the ozone layer starts to recover.
-Natural disasters are extreme, sudden events caused by environmental factors that injure people and damage property. Earthquakes, windstorms, floods, and disease all strike anywhere on earth, often without warning.
-Water Pollution: This example is one of the worst because if we are not aware probably there would not be drinkable water and all the people will die. Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, getting dissolved in them. This degrades the quality of water.
To conclude it's necessary to be aware of what human race is doing to our home and what is the contribution of every one. The world is in danger and we have to take care of it. We are preventing pollution: recycling, throwing away the garbage in the trash can and not using public transport or cars.
