My suggestions are:
1. Grow more creepers in apartments. This initiative can be taken by the apartment owner.
2. Terrace gardening for those who do not have garden space in front of their houses.
3. Grow tall trees with less shooting branches like teak, coconut than Mango and Jackfruit trees. As the branches spreading out of the compound may not be accepted by neighbours.
4. Grow more plants in pots which consume less water, so caring becomes easy.
Lead the leader
Now you are trying to plant a tree for your future generation. Your future generations also would do the same thing that you did now.
Nevertheless, let us plant a tree now and let it grow. We may not be there to see it. We do not know how our future generation would treat the trees?
