Predictions by  
Stephen Hawking 
Soaring CO2 emissions are damaging the planet's resources. 
Harvard University biologist Edward O. Wilson, said "If the World population reached 9 billion, this would be unsustainable, based on calculations of the Earth's available resources". 
What if the ozone layer disappeared? The ozone layer prevents most harmful UV wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which are projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. 
Five scientific predictions by Professor Stephen Hawking 
From catastrophic climate change to alien invasion, the theoretical physicist’s thoughts about what might lie ahead were often far from optimistic. 
Gene editing 
In his recently published posthumous collection of articles and essays, Brief Answers to the Big Questions, Stephen Hawking forecast that genetic editing techniques will give rise to a breed of “superhumans”, “a race of self-designing beings who are improving at an ever-increasing rate”. 
Artificial intelligence 
In 2017, the professor told Wired magazine that the AI “genie is out of the bottle”. He was fearful that developments in artificial intelligence will give rise to “a new form of life that will outperform humans”. 
Space exploration 
To ensure humanity’s survival, the theoretical physicist thought we would have to colonise other planets and solar systems. “Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth,” he told an audience at a Norwegian science and arts festival in 2017. 
Climate change 
Hawking also had concerns about climate change, which were amplified by the election of Donald Trump as president in 2016. “Trump’s action (pulling out of the Paris agreement) could push the Earth over the brink, to become like Venus, with a temperature of 250C and raining sulphuric acid,” Hawking told BBC News. 
Alien contact 
He also thought that should we make contact with extraterrestrials the outcome might not be positive. In 2010, he told the Discovery Channel: “If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans.”

Salt-Water Fish Extinction by 2048 
Some of the species most threatened by over fishing currently include Atlantic Halibut, Monkfish, all sharks, and Blue Fin Tuna. Other animals not usually associated with the seafood industry are also affected, with inadvertent by-catches claiming loggerhead turtles, sharks, dolphins and whales. 
In the future removing the fish we eat will result in the deterioration or loss of marine ecosystems around the globe; the oceans become full of algae and jellyfish. The oceanic food web collapses, many birds and sea mammals that eat fish also become extinct and many humans that rely on fish starve. 
Increasing population, mass migration to cities, increasing energy and soaring CO2 emissions damage the planet's resources beyond repair. 
Most alarming; climate-warming, carbon emissions increased 40% in the past 20 years, but two-thirds of that rise occurred in the past decade. 
Researchers say that global ocean water levels on Earth have risen about 19 centimetres in the last century. And the rate of rise is speeding up. The 20th-century average is about 1.7 millimetres per year; since 1993 the average rate has nearly doubled to about 3.2 millimetres per year. 
Core samples, tide gauge readings, and, most recently, satellite measurements tell us that over the past century, the Global Sea Level (GMSL) has risen by 4 to 8 inches (10 to 20 centimeters). 
During the most recent ice age (at its maximum about 20,000 years ago) the World's sea level was about 130 m lower than today, due to the large amount of sea water that had evaporated and been deposited as snow and ice, mostly in the ice sheet. Most of this had melted about 10,000 years ago. 
Around the World two acres of forest are cut down every second. 
It is estimated that within 80 years there will be no rain forests. Agriculture is the leading cause of deforestation. 
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. 
Other predictions, studies show that ongoing climate change and fossil fuel use will render much of the planet too hot for human life by 2300 
Theoretical physicist and futurist, Professor Michio Kaku predicts that in a mere 100 years, humanity will make the leap from a type zero civilisation to a type I civilisation on the Kardashev Scale. In other words, we'll become a species that can harness the entire sum of a planet's energy. Wielding such power, 26th-century humans will be masters of clean energy technologies such as fusion and solar power. Furthermore, they'll be able to manipulate planetary energy in order to control global climate. Physicist Freeman Dyson, on the other hand, estimates the leap to a type I civilisation would occur within roughly 200 years.

2029/2036/2068 approaches 
On April 13, 2029, Apophis will pass Earth closer than geosynchronous communication satellites, but will come no closer than 31,200 kilometres (19,400 miles) above Earth's surface.
