If there are trees on Mars how is there no oxygen there?
The presence of trees alone does not guarantee the presence of oxygen. Trees produce oxygen as a byproduct of photosynthesis, but for there to be a breathable atmosphere with sufficient oxygen, there would need to be a complex ecosystem supporting plant life on a large scale, including the recycling of carbon dioxide into oxygen. Additionally, Mars currently has a thin atmosphere that is not conducive to sustaining life as we know it.
What atmosphere we live on?
The main components of Earth's atmosphere are nitrogen and oxygen. Of these, oxygen is the one we can't live without.
Where did oxygen in the atmosphere came from?
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.

Why were insects so big hundred of millions of years ago?
One of the major factors limiting the size of insects today is the amount of oxygen in the atmosphere. Currently, the atmosphere is about 21% oxygen. At earlier times, the oxygen concentration was as high as 36%. Vertebrates now largely rule as the large land animals.
