Well, we may not be alive to see the year 2100, but just imagine that how our next generation will suffer and survive in the future, but the thing is we are currently running with 7 Billion+ populations, by the year 2100 our world population may be 10 Billion+ populations.
No need to think of the year 2100, this generation of 7 Billion populations suffering from poverty, hunger and regular change in the climate with many issues around. Since we have only one planet can we make it safe or simply becoming a part in destroying it?
Development
The development will not decrease in urban countries, as this will become common in building new cities and mega-cities, maybe each city with 10-20 Million populations became more common in those days.
Languages
There will be 100’s of languages disappearance by 2100, as we know that there are more than 7000+ languages all over the world at present, the most common language spoken English will be the top one all over the countries by the time and it will also be easy to communicate with everyone all over the world.
This New Generation
You new born ones or your baby grandchildren will be 60-75 years old by those days, according to today’s general survey, only 20-25% would survive up to 60-80 years.
More growth will be from Africa, its population will go 3.6Billion by 2100, but there are some regions which will have slower growth in population, example like the United States population may grow 311 million to 478 million
There may not be dead soon in the future after 2100, the present lifespan of humans is 65-68 years, and as well many medicines are being invented to prevent diseases which are hazardous for survival of life. If everything goes well as global warming planned humans may leave 70-80 years.
Shortage of Food
Our food may be more expensive in those days, because many people are trying to live a luxury life watching one another, who are going to worry about crops and farm cultivation, maybe the land besides the cities may fall in the real estate business with increase of population.
There may be a shortage of farmer to cultivate the crops and produce food.
Toxins Gaseous may arise
Rise of toxic gases may cause the extension of many species in air and also surroundings too. It is said that Carbon dioxide will rapidly increase if global warming is not kept in control.
