Humble request to Donate for Good cause
If you are donating a small amount, it will make a great impact with the helpless and needed people.
If you are providing food to a hungry people, at least it will give a temporary relieve, but if you teach or train the people to earn a little amount by themselves, it will be a permanent relieve.
Whoever have a lot of amount and they can invest to buy the rainforest trees and they can save the tree (by making a agreement that not to be logged at least for some years). During this time, the tree's growth will be a little profit, but the impact on the environment will be great. (I am a Greenpeace supporter.)
Whoever have a lot of amount and they can also invest with the agricultural and greenery projects in Africa where the devastating draught and hunger is affecting millions of people.
Whoever have a lot of amount and they can also invest with the R&D projects in medicine for AIDS and life saving drugs. At least they buy these type of medicine in bulk and they can sell to the affected people without any additional profit.
We have to respect the Animal's rights, but I was amazed, when there were some "crazy people left millions of Dollars to a Dog and Cat" while "millions of human still in hunger and poverty".
