Why I am afraid of the future

There are so many different theories to what will change- for example, people are fearing that the book '1984' will become reality in future years. Also, the fate that 'fahrenheit 451 predicted- I could not live without books! The main thing I am worried about, however, is the bleak and unforgiving future which lies ahead for the human race if we do not change our actions now, it is predicted that the world will be 10 times worse than it is today. A future timeline tells us that by 2050 half of the amazon rainforest would have been cut down. Fish size will have declined by nearly a quarter. By 2059 there will be no more oil. In 2060, 0.5% of animals and plants will go extinct per year- resulting in more carbon dioxide, because of the decrease in trees. Weather patterns will start to change, creating huge cyclones in the Mediterranean and many floods in New York. In 2069 the USA will reach a population of half a billion. Global average temperature would have risen by 4 degrees Celsius in 1970. The world does not look good. It is dangerous. Us humans have ruined our Earth. We have ruined what we were supposed to protect.
