I think that overpopulation. There is no bigger threat for human kind than us- humans.
According to Census.gov there are 7.8 billions of us right now on Earth.
We’re growing, drowning our Planet from resources Everyday. Statistically we are taking resources of 1,5 planets now. And it won’t change for better. There’s only one scenario that after 2100 population will start to decline, but it is not certain.
And then, there will be at least 10 billions of us, they predict.
We need to change something, otherwise we will face consequences that no human kind nor our Planet had to face ever before, such as:
1. Unemployment will rise- fewer jobs left because everyone needs to work, if there’s too much people simply more of them will become unemployed.
2. Costs of living will rise- More people will need to eat, live and work, in consequence there will be bigger demand for various essential commodities including food, real estate and healthcare.
3. Less accessible healthcare- it will take longer to get a proper treatment, goverments will be not able to pay enough money to fund
4. Epidemics and pandemics – people will live in more crowded spaces, bigger cities, often in poverty with no real access to the healthcare. Which leads to the emergence of new epidemics and pandemics.
SARS COVID 19 epidemic is probably one of them- it emerged where overpopulation can be observed.
5. Shortage of water – only 1% water on Earth is fresh and accessible. In 2025 humans will need 70% of fresh water available on Earth. Which will lead to massive human migrations, the biggest in the entire human history and extinction of the animals.
6. Lower life expectancy- A large portion of world’s population grow happends in less developed countries, lots of this children won’t survive or will have a short life.
7. Extinction- impact of human activity on wildlife is severe. Their habitats shrinks or they are completely destroyed, for people to be able to farm on it or they’re used for urbanization. At the end of 2100 half of our wild species will be extinct.
8. Depletion of Natural Resources- Currently we’re using more natural resources, than the Earth can produce in sustainable way. Which means we’re destroying our planet to survive. And it is going to be even worse.
9. Global warming-
