'' Demand an urgent cap on population explosion globally''

The present population of the world is 7.2 billion approx. and it is estimated to reach 10 billion in 2050. One can imagine how much heavy our mother is today and how much will it become in 2050.
If we don't stand today together, then, nature will do it in the cruellest way possible. Do you think any developmental goal will be achived without first looking into this? I would say every policy, laws or developmental policy should be put to halt and every country should put a cap on population explosion. For example, let's say put one family two child policy globally.
