Do you think that man should take better care of the planet?

Sure, but it's a question of benefit and cost. We could reduce the human population to 1/50th its current level and all live a simple agrarian lifestyle, or not do anything and preserve our current population and future growth through technological means without worrying about any impacts to other species. Two ends of a spectrum, we can choose either or something in between or something else.
I think we could fairly easily do a lot better job with what we have and know currently without having to sacrifice much in the way of how we live currently.

Every year temperatures across the globe go up and down to offset each other to result in an average global temperature that doesn't fluctuate wildly. The total energy reaching the earth, and the earth's ability to either keep or get rid of that energy is what impacts the globe's temperature.
But more local conditions can vary wildly. Global ocean currents have a huge impact on local weather, if those change then the total energy gets shifted around, resulting in different local conditions, but the energy doesn't just disappear or get created from nothing, so in general things have to balance.
