For thirty years, Peter Singer's Practical Ethics has been the classic introduction to applied ethics. For this third edition, the author has revised and updated all the chapters, and added a new chapter addressing climate change, one of the most important ethical challenges of our generation. Some of the questions discussed in this book concern our daily lives. Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? Am I doing something wrong if my carbon footprint is above the global average? Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research, and euthanasia; political violence and terrorism; and the preservation of our planet's environment. This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think about how she or he ought to live.
If you’ve never listened to the Philosophy Bites podcast, here’s a relevant episode on the status of animals:https://philosophybites.libsyn.com/christine-korsgaard-on-th...
Also here’s a thought: unnecessary harming of an entity is bad for its effect on you, ie one should refrain from killing an insect even if it did not feel pain. Same holds for a nice rock formation.
Some philosophers whose works I've read and enjoyed: Robert Nozick's Anarchy, State and Utopia; Derek Parfit's Reasons and Persons; Peter Singer's Practical Ethics; Graham Priest's In Contradiction; Graham Oppy's Arguing about Gods; Edward Feser's Five Proofs of the Existence of God – that's a rather eclectic and idiosyncratic list, including books by authors which radically disagree with each other (e.g. Feser's book tries to prove God exists, Oppy's book argues all known proofs of God's existence fail) - but you definitely won't find any of that "critical theory" cant in any of them
His Practical Ethics [0] and other books are excellent.
Primarily, I think it's important to very seriously think about our moral obligations to others, especially in today's interconnected world (where we not only can, but inevitably do affect others whether we like it or not).

You could start with this list [1] of resources. I'd like to add Practical Ethics by Peter Singer.
