Is global climate change man-made?

[This no longer has anything to do with my Environmental Science class, as I graduated high school long ago, but I saw plenty of debates online and felt like putting my opinion in here]

In a great part, man is responsible for Global Warming and any other changes in the environment. Inventing more and more machines and industries has been useful, yes, but all these mechanisms have greatly poisoned the environment, filling our planet with toxic gases and heat that cannot be reversed and has caused countless damage, not to mention what is to come. We have already lost so much to Global Warming, and unfortunately, it will not stop there. We will continue to lose frozen paradises, habitat for our animal species, the animal species themselves, the oceans will flood our land...countless damage. However, we do not listen and try harder to change things. The deeds that have already been done to make up for this damage are not enough, not at the rate the planet destruction is going. Grant it, it is also damaged through natural causes, but nature always has a way to repair what it does; be it natural fires, or floods, or droughts, etc. However, mankind does not. Up to date, the rivers, lakes, oceans, jungles, forests, animal species, plants...All these things that have been finished, destroyed, harmed, and contaminated by men have not been fully restored.

It is an outrage that animals have to opt for Zoo or captivity life in order to be somewhat safe, when they could be enjoying life out where they were born from the very beginning. Some animals don’t even know that there’s an outside world that their ancestors belonged in; they were born and raised in captivity. Some would say they have turn into shameful samples of the wild animals that they once were, but it is not the animals’ fault this is so. It’s not the frozen, or tropical paradises’ fault that they have ended. Nature does its best to replenish what has been lost; ocean and land flora and fauna, atmosphere health, and peace. But it is not possible for her to do all the work on her own, especially when we are doing anything but help. (Those organizations and people that ARE doing their best and trying their part are very appreciated, but sadly, it is not enough; we still have LOTS to do)

And most of the problem starts because humanity has started to care more about money and profit than anything else. Than keeping the world clean and beautiful; plant and animal life abundant and peaceful. For what other reason are fishes, seals, tigers, elephants, birds, deer, etc. hunted faster than they can reproduce? For many reasons, which trailed down to the right places and companies, eventually lead to profit; M-O-N-E-Y. Nothing else needs to be said.
