Well, there is no need to highlight the fact that the first environmental danger nowadays is global warming. Our climate changes drastically and it is impossible not to notice that. Yet, we still fail to do much in order to help save the planet. The problem of pollution is closely connected with the issue of global warming as pollution is one of those triggers which has caused the climate to change. However, there are lots of other reasons to mention when it comes to global warming.
Another serious aspect to mention is overpopulation. As a result, we have not figured out how to provide the whole mankind with water, food, shelter as well as basic medical care and educational programs.
What is more, it is important to mention the aspect of natural resources depletion which also presupposes that we should be more focused on using renewable energy sources. Lots of habitats are destroyed due to human activity which leads to loss of biodiversity and deforestation. There is a lot to be done in order to maintain our planet a safe place to live on.
