Environmental threats

As industrialization has been developing rapidly in the past centuries, the climate has been affected by human-activities, and Global warming is today considered as our biggest global threat. What threatens the environment?

 

Pollution and CO2 emissions

Human activities cause emissions of greenhouse gasses, especially co2 and steam, which has resulted in a global temperature increase. This is called the greenhouse effect which prevents the warmth on Earth to come out so the global temperature rises.

 

Co2 is a gas which occurs naturally on Earth, during the photosynthesis; and this, along with many other factors has caused skepticism about human caused global warming, and believes that the rising temperature is natural. Today, this debate has ceased, because of sufficient evidence that Global warming is a fact. The global temperature has increased more over the last seventy years, than in 1000 years of human history.  Too much CO2 in the atmosphere is dangerous for the global climate and our ecosystems. “Fortunately,” all plants live of this gas, and makes CO2 into oxygen in their photosynthesis. In spite of this advantage, we whale down our forests and the greenhouse effect will only become more extensive.
