There is nothing wrong with that, wishing to support an organization which wants to help to save the environment, the flora and fauna but you also need to do some due diligence on the organizations and agencies before you give away your hard earned dollars to them, you know. There are legitimate ones which operate on a non-profit base and they only use the money for good deeds and to pay for their operating costs, but there are also organizations which take advantage of the good will of people to take as much money as possible and under-deliver on their initial promises.
For example, PETA is one of the most infamous organizations which is supposed to seek for the well being of animals and the wild fauna as well, even though the are one of the biggest ones, their methods are nefarious and frown upon by most of reasonable people on the internet.
So,.do your own investigation and do not give your money to scammers.
