The ability to respond appropriately so as to enhance the living environment for all life is not a burden; if anything it is a liberation!
It is also a biological imperative, and it absolutely inhere's to all natural living processes.
The responsibilty of those who refuse to do so, to respond apropriately, for whatever reason, is indeed a burden.
Hence the denial. Hence the ultimate futility of that denial, for it is a prison of one's own making.
In a world of many prisons, that is the one most tractable, the easiest to escape.
Make your way to freedom.
Let ruthless self-honesty be your chain breaker.
Do what you love, it's your gift to universe
