Dear sinister

Its good to hear something from you

The solutions are their but problem is world will never accept it

The main problem of earth is not over population It is mainly population imbalance
On one hand sooth asia china etc are bursting with population

On the other hand countries like Russia,australia,canada etcare controlling vast land resource .If these countries will allow large scale immigration of farmers then food production could go up.But it is not going to happen because ethnic,linguistic,cultural pride is too much.I find it quite surprising when people call themself Humanist but they and speak against religion as it divides humans but hardly any of them speak

against dividing this world in countries.

As far as energy is concerened developed countries should reduce consumption of energy.Just check the retail price of US petrol and india It is around rs.36 in Us while it is rs.47 in India.where every other commodity is expensive their petrol is cheap

why?

Countries like USA should develop public transport ,provide pick up and dropping facilties for employees just like Indian BPO and It companies as it will save much
more oil

But No one is going to implement these solution
