Recently, diseases that are caused or transmitted by insects, rats and contaminated water have reappeared, mainly after the increase in heat from the El Nino phenomenon and global warming, which alter the climate and promote droughts and/or floods.
The El Niño phenomenon was most noticeable between 1997 and 1998, when the increase in temperature (heat) killed thousands of people. people in different parts of the planet, the most affected countries were the European continent, the United States and India.
Climate change does not only affect human lives, rising temperatures at a global level increase the chances of disease occurrence. from bacteria, fungi, viruses and protozoa that establish themselves in hosts of all species distributed throughout the planet, whether aquatic or terrestrial.
Some information on this subject was published in the journal Science 2002, the edition presented a list of possible problems arising from global warming in all biomes and ecosystems. In this context, according to the scientists, corals are the ones that suffer the most from rising temperatures in the oceans, in the years when the El Niño phenomenon was more in decline. evidence occurred the incidence of disease and mortality of molluscs, as well as direct impact on corals constituted by cnidarians in different places of the world. In addition to corals, other marine creatures were affected, especially the most fragile life forms.
Among the many forms of life that can be affected by global warming, there are plants, some of them have immunity to fungi and viruses, however, climate variation can reduce it.
In Hawaii, some species of birds are at risk because of the mosquitoes that host malaria. mosquito only remained in areas of low relief, but with the increase in temperatures they have dispersed to local taller.
All climatic phenomena such as El Niño, La Niña, greenhouse effect and global warming, have in recent years presented negative reflections of what man has done and it still continues to perform in the biosphere, in the face of anthropic actions, even those who are not at fault as animals and plants are harmed, however, man or society as a whole it has not yet awakened to the dimension of climate and environmental problems that can put at risk the proliferation of living beings in which man himself is inserted.
Every action has a reaction, in this way, nature is giving back what we produce.
Do not stop now... There's more after the advertising ;)
