PLANET EARTH it took 200,000 years for the population to reach 1 billion, this was in the year 1800, 127 years later it reached 2 billion and only 33 years after that by 1960 it reached 3 billion, and by 2011 it had reached 7 billion, 9 years later in 2020 it's 7.8 billion as of January 2020 according to the most recent United Nations Worldometer.
The Laqucia report projection, the current world population of 7.8 billion is expected to reach 9 billion by 2030, 12 billion by 2060, however by this time Planet Earth will undergo many changes and new threats to the human race.
Coral reef in danger due to sea temperatures rising, over fishing and siltation, however science, new technology and careful planning management systems introduce new types of coral that thrive in warmer temperatures, this all helps but the ocean is in great danger of becoming polluted by 2048.
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. New laws will be introduced trying to prevent over fishing. Governments try to replenish fish stocks, but by 2048 it's a case of too little too late, due to population expansion and despite these new laws many countries ignore the warnings.
Removing the fish we eat resulted in the deterioration or loss of marine ecosystems around the globe; the oceans became full of algae and jellyfish. The oceanic web was in great danger, many birds and sea mammals that eat fish were in danger of becoming extinct and many humans that rely on fish faced struggles to survive.
2020 Earth's population is growing with numerous environmental and social factors such as pollution, malnutrition, overcrowded living conditions, and lacking health care which makes poor communities vulnerable to infectious diseases. Diseases such as tuberculosis, malaria, HIV, and dysentery spread faster in overpopulated areas, and the threat of new viruses posed a big problem in the future.
Earth's environment getting worse, not better, Increasing population, mass migration to cities, increasing energy and soaring CO2 emissions are damaging the planet's resources.
Any solution to rectify the situation will come at a great cost with huge sacrifices needed that will be difficult to put in place.
Most alarming; 2020 climate-warming, carbon emissions increased 40% in the past 20 years, but two-thirds of that rise occurred in the past decade.
Water security is a growing concern in many parts of the world as population and agriculture drives demand, placing enormous stress on freshwater ecosystems and fishing zones.
A decline in freshwater species in tropical areas, which have shown a drop of 70% since 1970.
70% of the Earth's surface is covered by the ocean. The people of Earth sometimes forget how essential the ocean is for the water you drink, the air you breathe, for human activity and for life. Year after year the people of Planet Earth have been pushing the boundaries of the ocean’s sustainability.
The list of the ocean’s troubles is long, but one item demands immediate attention: harmful fisheries subsidies. Nearly 90% of the world’s marine fish stocks are now fully exploited, over-exploited or depleted. There is no doubt that fisheries subsidies play a big role. Without them, it would slow the over-exploitation of fish stocks, deal with the overcapacity of fishing fleets, and tackle the scourge of illegal, unreported and unregulated fishing.
